Prostate biopsy was performed using 3D models of prostate reconstruction, computer-simulated biopsy, 3D printing, and cognitive fusion biopsy. All patients had received multiparametric 3.0 T magnetic resonance imaging before the biopsy. The MRI DICOM files were imported using medical imaging software for 3D reconstruction modeling to generate a printable stl file for 3D printing, using transparent resin as the raw material. A biopsy of 2 to 3 cores was performed with suspected lesions detected on magnetic resonance imaging. | For the 16 patients in the present study, 3D modeling with fusion-based cognitive targeting biopsy was successful. For a single patient, 1-2 lesions (average: 1.1 lesions) were discovered, followed by 2-6 cores (average: 2.4 cores) added as target biopsy. Systematic biopsies represented a total of 192 cores, with a positive rate of 22.4%; targeted biopsies represented a total of 39 cores, with a positive rate of 46.2%. Among these cases, 10 patients (62.5%) were diagnosed with prostate adenocarcinoma, in which seven were discovered by systematic and targeted biopsy, one was diagnosed by systematic biopsy only, and two were diagnosed by targeted biopsy only. For systematic biopsy, the Gleason score ranged from 6 to 8 (average: 7), while for targeted biopsy, it ranged from 6 to 9 (average: 7.67). Among the seven patients who were diagnosed by systematic and targeted biopsy, three (42.8%) were reported with a higher Gleason score in the targeted therapy than in the systematic biopsy. | The 3D printing technique was applied to aid cognitive fusion in the early diagnosis of prostate cancer, which significantly improved the positive biopsy rate and avoided misdiagnosis of high-risk prostate cancer. This technique proves to be easy and simple. The increased effort in targeted biopsy does not increase the incidence of complications.

The scanning sequence included T1-weighted, T2-weighted, DCE, and DWI. | The prostate is a soft tissue organ, so processing MRI data images is more difficult than that of bones, teeth, and other tissues. In the data modeling phase, a lot of recognition of pelvic anatomy is required, with the help of imaging professionals. Therefore, based on various multiparametric magnetic resonance fusions, targeted biopsy cannot completely replace systematic biopsy. The development of targeted biopsy is based on more sensitive advances and specific imaging technologies. |
| GME2 | Surgical planning biomodels | Biomodels | ME18 | Explore the effect of 3D printing-assisted cognitive fusion on improving the positive rate of prostate biopsy. | From August to December 2014, 16 patients with suspected prostate lesions were detected by multiparametric magnetic resonance imaging (MRI) and included in the study. Prostate biopsy was performed using 3D models of prostate reconstruction, computer-simulated biopsy, 3D printing, and cognitive fusion biopsy. All patients had received multiparametric 3.0 T magnetic resonance imaging before the biopsy. The MRI DICOM files were imported using medical imaging software for 3D reconstruction modeling to generate a printable stl file for 3D printing, using transparent resin as the raw material. A biopsy of 2 to 3 cores was performed with suspected lesions detected on magnetic resonance imaging. | For the 16 patients in the present study, 3D modeling with fusion-based cognitive targeting biopsy was successful. For a single patient, 1-2 lesions (average: 1.1 lesions) were discovered, followed by 2-6 cores (average: 2.4 cores) added as target biopsy. Systematic biopsies represented a total of 192 cores, with a positive rate of 22.4%; targeted biopsies represented a total of 39 cores, with a positive rate of 46.2%. Among these cases, 10 patients (62.5%) were diagnosed with prostate adenocarcinoma, in which seven were discovered by systematic and targeted biopsy, one was diagnosed by systematic biopsy only, and two were diagnosed by targeted biopsy only. For systematic biopsy, the Gleason score ranged from 6 to 8 (average: 7), while for targeted biopsy, it ranged from 6 to 9 (average: 7.67). Among the seven patients who were diagnosed by systematic and targeted biopsy, three (42.8%) were reported with a higher Gleason score in the targeted therapy than in the systematic biopsy. | The 3D printing technique was applied to aid cognitive fusion in the early diagnosis of prostate cancer, which significantly improved the positive biopsy rate and avoided misdiagnosis of high-risk prostate cancer. This technique proves to be easy and simple. The increased effort in targeted biopsy does not increase the incidence of complications. Its application and popularization will surely benefit more patients on a larger scale in the future. | Aesthetics | The material application can intuitively show the location, size, and morphology of the tumor. | The files .stl were printed with a thickness of 0.1 mm. The printing material was transparent resin, and inside the suspicious defect was colored. | Before the biopsy, the operator can observe a 3D model of the tumor from multiple angles, thus evaluating the possibility of sampling by systematic biopsy or cognitive fusion. |

The elastic constants are determined and the influence of the filling percentage on the mechanical strength of the material is evaluated. Elastic finite element modeling of a prosthetic foot subjected to bending. Failure modeling of the prosthetic foot using laminated composite material failure theory. Perform tests on the prosthetic foot to validate the models. | A design of experiments was carried out in order to characterize the properties of the material as a function of the direction and filling percentage. The experiment was conducted in two stages. In the first stage, experiment A, the filling direction was varied and the filling percentage was fixed at 100%. In the second stage, experiment B, the filling percentage was fixed at 33% and the direction was varied. The response variables are: modulus of elasticity, yield strength, and tensile strength. The experimental factors are: printing direction and filling percentage. The material is modeled as linear elastic and transversely isotropic. The elastic constants were used to model the elastic behavior of a prosthetic foot using finite element analysis with the SolidWorks/Abaqus program, and failure models for laminated composite materials were used to predict the mechanical failure of the prosthetic foot. Finally, the modeling of the prosthetic foot is corroborated in a bending experiment at the tip of the foot with the ankle fixed, using a universal testing machine and a mechanical press. | It is observed that the mechanical properties do not vary significantly in the direction of the printing layer and vary significantly in the perpendicular direction of the same, which allows modeling the material as linear elastic and transversely isotropic. The filling percentage significantly influences the mechanical properties of the material, it is observed that there is a linear variation of the properties with respect to the filling percentage. The actual elastic behavior of the foot corresponded to what was predicted by the linear elastic and transversely isotropic model and the finite element simulation. The failure did not occur as predicted by the Tsai Hill/Tsai Wu mechanical failure model for laminated composite materials. | The experimentally characterized the mechanical properties of ABS in the 3D printing process, a transversely isotropic behavior was found, the mechanical properties are significantly different in the layer plane and in the direction perpendicular to it. The elastic constants of the material are: E1=1.700GPa, E3=1.230GPa, v12=0.24, v13=0.24 and G13=0.728MPa. The influence of the filling percentage was evaluated and it was found that the material complies with the law of mixtures of continuous media. The experimental results on the prosthetic foot were consistent with the theoretical modeling for elastic behavior but not for mechanical failure. | see ME82 | see ME82 | see ME82 | see ME82 |

The materials of the strings must be rigid and non-stretchable, but resistant to wear and able to withstand loads without breaking. The socket or coupling with the patient's stump should facilitate adjustments with the stump by thermoforming. | To achieve finger retraction, polyurethane joints are used between the fingers for a strong and precise grip. ABS rigid material is used for the fingers and the rest of the prosthetic body casing to enhance grip. Neoprene adapted gloves are also used to increase friction. The selected strings are 4-strand braided fishing line made of Polyethylene (PE), with a diameter of number 8, capable of supporting a load of 100 Lb. In the case of electromechanical prosthetics, the socket is conventionally manufactured using conventional materials. In the case of electromechanical prosthetics, scaling the print to fit measurements is an option, and/or final adjustments can be made using thermoforming on ABS coupling, but preferably on PLA. | By trial and error, the existing system is modified and improved. |

The work groups interview the patients in order to personalize the client's preferences and incorporate them into the cover design. The groups develop the concepts and manually manufacture them. The evaluation jury, composed of the teacher and the researchers, judge based on general guidelines of aesthetics, concept, personalization of the patient's taste, manufacturability, among other criteria. The best designs are chosen, and they are modeled in 3D and manufactured using 3D printing with ABS material at a reduced scale. Subsequently, covers are manufactured at full scale and some covers are coated with transparent epoxy resin, and then painted with polyurethane paint to verify the aesthetics and final finish. | The students led by the classroom teacher develop and manually manufacture cosmetic covers that reflect the personal tastes of the patients. The best designs combine the best geometries, colors, and simplicity that facilitate and guarantee the feasibility of manufacturing through the 3D printing process. Subsequently, covers are manufactured on a reduced and natural scale, and tests are carried out with resins and paints, further improving the finish and appearance of the covers, obtaining the best results for epoxy coatings and polyurethane paints. | It is concluded that industrial design adds high added value to the covers, not only by reflecting specific tastes of patients by customizing the covers, but also by developing concepts beyond patients' expectations. The combination of colors and geometry gives a better appearance to the cover as a product and ensures simplicity in manufacturing.

The resistance of the joints is tested. | The most economical and fastest manufacturing process is the use of indirect thermoforming by 3D printing with ABS, combined with laser cutting of PETG/High Impact Polystyrene sheet, and the use of standard sizes. The resulting PETG cover does not exhibit the interlaminar weakness of conventionally manufactured printed materials. This cover is ideal for patients/customers with high physical activity, including jumps, falls, and impacts with blunt objects. Among the limitations, it shows an increase in labor and manual work, as well as the presence of a mold, and the restriction of handling size, which reduces customization. The manufacturing process of cosmetic covers by direct 3D printing proved to be feasible for a sufficient wall thickness, reduction of stress concentrators, and the combination of xtc 3d epoxy resin to withstand loads and impacts that would otherwise fracture the ABS cover due to interlaminar weakness. However, it is recommended for patients with intermediate physical activity such as small falls and mild impacts. Another additional advantage is customization without excessive additional costs, but there is a limitation in the manufacturing size dependent on the printer size, which would require in some cases manufacturing in parts. A last intermediate case between the previous two is the thermoforming of PLA printed material, but it is limited by the printing area that limits the developed surface to be printed. It has the advantage that it is printed in a strong printing direction, eliminating the interlaminar weakness defect. However, like the first process, it requires direct intervention and manual work for thermoforming, in addition to the mold and limitations in customization associated with the printing area and specific size. In general, more development is required for the cover fastenings, which do not have sufficient strength. | In general, it can be concluded that there are different methods of manufacturing covers using directly or indirectly 3D printing, each with its advantages and disadvantages and specific application according to the physical activity of the type of patient. | Aesthetic | It should be aesthetic, with low surface roughness, and according to the patient's criteria: it includes conventional shapes and colors similar to the patient's original limb; and on the other hand, extravagant shapes with striking colors, and low relief tattoos according to the patient's taste. | As a master translator, I have translated the provided data into English. Here is the As for the conventional shape, it was designed with reference to the measurements and curved shapes of a normal leg. The cover was printed in ABS using FFF and polished with sandpaper to reduce roughness, apply epoxy resin, and paint with polyurethane. As for the extravagant and personalized shapes, in addition to the conventional shape, customized designs are used, whose concepts were inspired by the tastes of the patients but developed by industrial design students. | Over time, several covers are printed at full scale and different combinations are tested on each of them, without polishing, with tool polishing, manual sandpaper polishing, with epoxy resin, flexible resin, with paint on the resin, with paint without resin, and the texture and appearance result is judged. |

The resulting PETG cover does not exhibit the interlaminar weakness of conventionally manufactured printed materials. This cover is ideal for patients/customers with high physical activity, including jumps, falls, and impacts with blunt objects. Among the limitations, it shows an increase in labor and manual work, as well as the presence of a mold, and the restriction of handling size, which reduces customization. The manufacturing process of cosmetic covers by direct 3D printing proved to be feasible for a sufficient wall thickness, reduction of stress concentrators, and the combination of xtc 3d epoxy resin to withstand loads and impacts that would otherwise fracture the ABS cover due to interlaminar weakness. However, it is recommended for patients with intermediate physical activity such as small falls and mild impacts. Another additional advantage is customization without excessive additional costs, but there is a limitation in the manufacturing size dependent on the printer size, which would require in some cases manufacturing in parts. A last intermediate case between the previous two is the thermoforming of PLA printed material, but it is limited by the printing area that limits the developed surface to be printed. It has the advantage that it is printed in a strong printing direction, eliminating the interlaminar weakness defect. However, like the first process, it requires direct intervention and manual work for thermoforming, in addition to the mold and limitations in customization associated with the printing area and specific size.

In the case of PETG, wall thicknesses above 3mm are recommended. For high impact polystyrene and ABS/PLA, thicknesses between 2mm and 3mm are recommended. | After the covers were manufactured, they were subjected to manual static loads to corroborate the flexibility of the cover. |

ABS printed directly in 3D was selected, as well as PLA printed directly in 2D and thermoformed by 3D molds in ABS. Depending on the thickness, the materials behave rigidly. All materials can be painted, but only ABS can be sanded directly. | An experimental process on specimens and covers, and field tests with the patient, allows us to conclude the influence of interlaminar impact resistance of printed covers as a limitation in the functionality of the cover under loads, promoting the use of materials with high impact resistance, coatings, and thermoforming process to avoid interlaminar weakness of printed material.

The size or size of the cover, the printer, and laser cutter, and its speed limits the number of parts per cover assembly, as well as the number of printers/cutters to meet demand. The demand for prostheses in the country was estimated at 1000 units per year. | For direct 3D printing, contact is necessary and limited to sanding, epoxy resin application, and painting processes. For indirect thermoforming processes, physical contact is much greater. Depending on the size of the cover and the volume of the printer and cutter, the cover will be manufactured in multiple parts or as a single piece. Similarly, the monthly/annual production will determine the number of printers and cutters required to meet the demand. The demand for prosthetics in the country was estimated at 1000 units per year. In the case of 3D printing, around 10 printers would be required. | The type of manufacturing is dependent on the desired level of customization and physical activity requirements of the patient. For maximum customization and low physical activity, 3D printing is ideal and only requires direct contact during painting. The size and production of the cover will control the necessary sizes of printers and cutters and their number in the company. |

The dynamic and mechanical behavior of the prosthetic foot and knee under loads and conditions according to international ISO standard 10328:2006 was modeled and simulated using finite element analysis. Initial prototypes were developed using PC materials for the polycentric two-axis knee (M4B) and dynamic foot in TPU. Universal machine tests confirmed the correct dynamic behavior of the foot. In terms of static strength tests according to international ISO standard 10328:2006, the foot did not suffer any damage, but the knee broke during the flexion test due to the anisotropic behavior of the 3D printed material. The final prototypes were designed and manufactured using the plastic injection process, selecting new materials according to the technical data sheet of injected materials, and verifying failure efforts through modeling and finite element analysis. The final materials used for the knee were nylon 6.6 and for the foot, TPU with a hardness of 75 Shore D (between 90 and 100 Shore A). The foot test according to the standard was successful according to theoretical/numerical modeling. The theoretical/numerical modeling of the knee is also successful (the test could not be performed due to local COVID-19 quarantine). | By means of 3D printing, it was possible to develop a prosthetic foot capable of passing the static tests of the international ISO 10328:2006 standard without suffering damage. As for the prosthetic knee, due to the anisotropy of the material, it experienced mechanical failure during the tests in the weak plane due to manufacturing.

Technological transfer of the project through the hiring of a SENA apprentice to support the project. | Through 3D printing, 3D printed materials (FFF) were characterized. The dynamic and mechanical behavior of the prosthetic foot and knee under loads and conditions according to international ISO standard 10328:2006 was modeled and simulated using finite element analysis. Initial prototypes were developed using PC materials for the polycentric two-axis knee (M4B) and dynamic foot in TPU. Universal machine tests confirmed the correct dynamic behavior of the foot. In terms of static strength tests according to international ISO standard 10328:2006, the foot did not suffer any damage, but the knee broke during the bending test due to the anisotropic behavior of the 3D printed material. Final prototypes were designed and manufactured using the plastic injection process, selecting new materials according to the technical data sheet of injected materials, and verifying failure stresses through modeling and finite element analysis. The final materials used for the knee were nylon 6.6 and for the foot, TPU with a hardness of 75 Shore D (between 90 and 100 Shore A). The foot test according to the standard was successful according to theoretical/numerical modeling. The theoretical/numerical modeling of the knee is also successful (the test could not be performed due to local COVID-19 quarantine). | By means of 3D printing, it was possible to develop a prosthetic foot capable of passing the static tests of the international ISO 10328:2006 standard without suffering damage. As for the prosthetic knee, due to the anisotropy of the material, it experienced mechanical failure during the tests in the weak plane due to manufacturing. The redesign of final prototypes to be manufactured by plastic injection ensures that in the theoretical/numerical modeling, the elements do not suffer damage when subjected to tests according to the standard, and this was corroborated in reality for the foot. The manufacturing costs for plastic injection are much lower than those for FFF 3D printing, even at a production rate of 50 for the foot and 100 units for the knee. | Useful Life and Maintenance | support a dynamic load of 1230N for 2x10^6 cycles. | Expected An expected lifespan of between 1 year (2 x 10^6 cycles) for printed materials to 3 years for conventional materials. | Printed materials have lower fatigue and impact resistance than conventional materials. |

Technological transfer of the project through the hiring of a SENA apprentice to support the project. | Through 3D printing, 3D printed materials (FFF) were characterized. The dynamic and mechanical behavior of the prosthetic foot and knee under loads and conditions according to international ISO standard 10328:2006 was modeled and simulated using finite element analysis. Initial prototypes were developed using PC materials for the polycentric two-axis knee (M4B) and dynamic foot in TPU. Universal machine tests confirmed the correct dynamic behavior of the foot. In terms of static strength tests according to international ISO standard 10328:2006, the foot did not suffer any damage, but the knee broke during the bending test due to the anisotropic behavior of the 3D printed material. Final prototypes were designed and manufactured using the plastic injection process, selecting new materials according to the technical data sheet of injected materials, and verifying failure stresses through modeling and finite element analysis. The final materials used for the knee were nylon 6.6 and for the foot, TPU with a hardness of 75 Shore D (between 90 and 100 Shore A). The foot test according to the standard was successful according to theoretical/numerical modeling. The theoretical/numerical modeling of the knee is also successful (the test could not be performed due to local COVID-19 quarantine). | By means of 3D printing, it was possible to develop a prosthetic foot capable of passing the static tests of the international ISO 10328:2006 standard without suffering damage. As for the prosthetic knee, due to the anisotropy of the material, it experienced mechanical failure during the tests in the weak plane due to manufacturing. The redesign of final prototypes to be manufactured by plastic injection ensures that in the theoretical/numerical modeling, the elements do not suffer damage when subjected to tests according to the standard, and this was corroborated in reality for the foot. The manufacturing costs for plastic injection are much lower than those for FFF 3D printing, even at a production rate of 50 for the foot and 100 units for the knee. | Legal Aspects | According to Standard ISO 10328:2006, Comply with the criteria of resistance and durability of the standard, and invima registration along with compliance with other workplace conditions. | Standardized tests are performed in a certified laboratory. | The standard is analyzed, the different tests are synthesized, the necessary tools are managed to reproduce the tests according to the standard, and the test is performed. |

The removal of support material may require the use of a heated chemical solvent, which is difficult to implement in a hospital with limited space and safety concerns. The sparse structure built by the same material (Nylon) and removed by the sanding process with tape is being investigated with reasonable success (This requires further research to optimize the FDMTM process for the AFO). The structural integrity of an AM-manufactured AFO can be tested in three ways: 1) experimental bending test by fixing the foot region and applying a load on the top (near the knee) of the AFO, 2) FEA simulation of this bending condition with assumptions for the boundaries and loading conditions, and 3) a healthy subject using the AFO and exerting high forces on the AFO to test under extreme load. | The thickness depends on the FDMTM machine as well as the flexibility and structural strength of the AFO for patients. The thin contour section of the AFO shell can be filled using the wavy and scattered structure, and it can increase the strength (by increasing the thickness) and reduce the manufacturing time of the AFO. The material property, construction orientation, and tool paths are three key parameters of the FDMTM process for AFOs. Carbon Nylon has the highest strength and was initially selected due to its lightweight capacity. The initial evaluation of the patient's AFO reveals that AFO compliance is critical.

Four key components: 1) digital scanning of the foot and leg geometry using a support with a transparent plate for the foot and an ergonomic procedure for 3D optical scanning, 2) cloud-based design software that allows clinicians to access scanned point cloud data on the geometry of patients' feet, as well as create 3D models for patient-based AFOs, 3) cloud-based manufacturing software that generates tool paths and process parameters for additive manufacturing to fabricate the AFO, 4) evaluation using the inertial measurement unit (IMU) for AFO motion measurement for gait analysis. | This CDAM system helps to shorten delivery and improve the fit and comfort of custom orthoses and prostheses. Traditionally, custom orthoses are made using plaster molds that require multiple patient visits and a lot of time and work for manufacturing. The feasibility of the CDAM system for one-day delivery of AFOs to patients has been demonstrated. | In this work, an application of a CDAM system that has been implemented for practical design and manufacturing, as well as for evaluations of patients with customized AFOs in a clinical environment at UMOPC, was presented. The potential of CDAM to improve clinical services for personalized AFOs and enhance the patient experience by allowing a one-day visit has been demonstrated. The ongoing research aims to demonstrate that this CDAM system is sustainable and reliable in operation. Furthermore, with the use of cloud computing, cybersecurity and privacy issues, including data confidentiality, integrity, and availability, are important for the CDAM system to address. | Legal Aspects | The ISO 22523 standard has outlined the general requirements and test methods for AFOs. Static, fatigue, and impact tests are conducted for AFOs produced by FDMTM to ensure the safety of human participants in clinical evaluation. These tests simulate the load that AFOs experience during various walking conditions. The amount of force, the location of application, and the means to control the force of an orthosis vary from person to person. Therefore, MEF and patient tests are necessary. | The structural integrity of an AF0 manufactured by AM can be tested in three ways: 1) the experimental bending test by fixing the foot region and applying a load on the top (near the knee) of the AFO, 2) the FEA simulation of this bending condition with assumptions for the boundaries and loading conditions, and 3) a healthy subject using the AFO and exerting high forces on the AFO to test under extreme load. | Technical requirements for mechanical resistance. |
| GME3 | Design and manufacture of Prosthetics and Orthotics. | Superior orthosis | 206 | In the study, a 3D printed splint model has been proposed, which replaces the deficiencies of the mold while maintaining its virtues. | The proposed methodology is based on three-dimensional digitization techniques and 3D modeling with reverse engineering software. The work integrates different scientific disciplines to achieve its main objective: improving the quality of life of the patient. In addition, the splint has been designed based on the principles of sustainable development. The splint design is made of polycarbonate using Additive Manufacturing with fused deposition manufacturing technique, and conceived with organic shapes, customizing the openings and closing the buttons with rubber. | The prototype of the designed splint has been successfully printed for testing its optimal fit to the arm. The assembly of the prototype was done using the 3D printed arm model for verification purposes. The final result is a scaled-down 3D printed arm splint prototype using PLA as the material. | The achievements in this work have been the study, design, prototype, and 3D printing with the AM technique of an orthopedic arm immobilization product. This has allowed improving some characteristics of traditional splints such as: Water resistance that improves personal hygiene; Cost reduction due to the choice of material used; Recyclable product; Lightness; Pleasant and innovative aesthetics; An orthopedic product for immobilization that allows visual control of the skin and anticipation in the application of physiotherapeutic treatments during the immobilization period; A biocompatible splint that does not irritate the skin and promotes skin ventilation. | Function | Reducing complications associated with immobilization period due to lack of visual control of the affected area. Possibility of applying physiotherapeutic techniques during the immobilization period for the initiation of patient rehabilitation and to accelerate their functional readjustment. Contribution to improving the patient's quality of life in terms of personal hygiene and skin care. | Design of aesthetic and functional openings, their organic circular shape, and the rubber button as a closing system. Application of three-dimensional scanning techniques and modeling through the use of reverse engineering software. | The presence of the openings allows ventilation and provides the possibility of washing the affected area, improving the patient's recovery period to avoid sweating, allergic reactions, changes in the skin, and allowing visual control of the injured area, favoring the doctor's diagnosis in periodic reviews. In addition, they reduce the risk of pressure syndromes such as Südeck's algodystrophy and, in terms of safety, contribute to the visibility of the limb, avoiding the possibility of hiding weapons in the splint. Venous return and lymphatic drainage are achieved through the design of specific windows for access to lymphatic drainage points. The use of muscle electrostimulation prevents the loss of muscle mass in the affected limb and, consequently, reduces the period of functional rehabilitation. The application of physiotherapy techniques before removing immobilization through the use of iontophoresis, sonotherapy, laser therapy, magnetotherapy, and hydrotherapy. The organic shapes of the holes have been chosen in part for the resistance they provide compared to geometric figures that promote breakage due to the accumulation of stresses at their vertices. In addition, the organic shape is more hygienic compared to those designed with vertices. In fact, they prevent deposits, facilitate cleaning, provide simplicity and lightness, and allow customization, giving a less hospital-like appearance than traditional orthopedic casts. Customization allows for an attractive and personal aesthetic that identifies the splint as a non-orthopedic supplement and prevents the patient from feeling less convalescent or sick. Rubber button and closure system This type of closure represents a cheap and discreet solution. The two pieces that make up the splint are held together by buttons with rubber bands. The rubber button and closure system are very efficient and very easy to use. The proposed closure system does not cause any cleaning problems either. It also allows for the detachable joining of its parts and therefore the occasional removal of the splint to establish visual control in medical reviews. |

Consequently, the structured light digitization technique or active triangulation was chosen using the 3D Spectra™ scanner. The result of an individual patient's scan provides a cloud of that vision, which is processed through what is known as reconstruction, where points that are not of interest for the study must be excluded, and the 3D model of the stump surface can be generated as shown in Figure 1, and converted to the STL format, which is a solid file for printing, to subsequently perform the 3D prosthesis modeling, since the prosthesis design is subject to the anatomy of the amputated stump. | Considering the expertise of the prosthetist and the patient's feedback on discomfort and rubbing. |

With these technologies, it is possible to design and manufacture orthopedic aids quickly and efficiently, which have many advantages for both patients and doctors: low material consumption; automated production; an easy, comfortable, airy, and visually appealing solution for the patient; cost savings; greater precision of orthopedic aids (by shaping the PLA material). | Function / customization | The use of these methods of design and manufacture of an individual orthopedic aid has been found based on a review of the literature in the field of medicine. Currently, the mentioned methods are used, whose choice depends on the case, respectively, on the type and extent of the patient's injury. | 3D Model: An individual orthopedic corset is created using CAD software according to the data obtained through 3D scanning of a model that will be designed and manufactured in the specific shape and size for the particular patient, and can be used after production. 2D Model: An individual orthopedic corset is designed and manufactured in a planar form, meaning it is created as a unfolded 3D model using CAD software based on data obtained through 3D scanning (active triangulation). This model will be shaped (i.e., molded) onto the patient's body after the model is produced. Obtaining the desired 3D digitized model of the body part using active triangulation, editing, and converting it to the STL format (input format for AM). | 3D Model: Variant A was created in Autodesk PowerSHAPE software. In the first step, it was necessary to create curves in the scanning model through a dynamic section. Subsequently, it was possible to create surfaces between the curves. This design and manufacturing variant emphasized minimizing material consumption, saving manufacturing time, and reducing production costs while maintaining device strength and functionality. In variant B, the brace was created using Autodesk Meshmixer software. The surface model from Autodesk PowerSHAPE software needs to be reintroduced into the polygon mesh. 2D Model: The benefits of this variant compared to the previous two '3D' model variants are as follows: lower material consumption, shorter production time, greater accuracy of shapes and dimensions after shaping in the patient's body. |

| GME3 | Design and manufacture of Prosthetics and Orthotics. | Lower limb orthosis | 287 | Design and creation of prototypes through additive manufacturing of a functional splint for the rehabilitation of Achilles tendon rupture. | The custom design of the splint begins with a scan of the limb. The 3D Systems Sense® scanner is used for this purpose. Once the file is generated, it is exported to the 3D Systems Geomatic Design X® CAD (Computer Aided Design) program. This program allows the transformation of the point cloud into a surface (This surface is the base of the solid that constitutes the splint). The surface is exported to the CAD program Rhinoceros 5, specialized in 3D modeling, to solidify the surface, model, and design the orthosis before printing. A splint consisting of 4 pieces is obtained: an inner piece made of flexible material and three outer pieces made of rigid material. Two of these outer pieces make up the body of the splint, and the other is a removable cover for one of the treatment windows. | The result allows for the application of simultaneous rehabilitation techniques during the immobilization stage of the affected limb to minimize possible muscular, articular, and vascular complications derived from the use of traditional retention devices in this phase of treatment. | Technology allows the production of individualized immobilization splints through advanced manufacturing techniques based on additive manufacturing, industrial digitization, and reverse engineering. The rehabilitation treatment performed by additive manufacturing allows integrating the necessary characteristics to use physiotherapy techniques at this stage. The application of physiotherapeutic techniques in the immobilization stage prevents possible muscular, articular, cutaneous, and vascular complications derived from the use of traditional devices. The advantages or improvements in the immobilization stage, thanks to the use of functional splints made by advanced manufacturing techniques, can be summarized in two groups: continuous control and surveillance measures, and active techniques in the field of physiotherapy. | Function/Customization | Provide functional features to a splint for partial Achilles tendon rehabilitation in its initial design. | The custom design of the splint begins with a scan of the limb. Once the file is generated, it is exported to a program that allows the transformation of the point cloud into a surface. This surface is the base of the solid that constitutes the splint. It is divided into different flexible zones for patient comfort, rigid zones for immobilization, windows for accessibility and treatment, a window for the fingers, and a closure system. The treatment is estimated to last 8 weeks, including functional readjustment. Weeks 1 to 4 will be without support, week 5 with assisted support using crutches, and weeks 6 to 8 with autonomous support. The proposed rehabilitation techniques are: cryotherapy, lymphatic drainage, sonotherapy, magnetotherapy, laser therapy, iontophoresis, muscle electrostimulation, and electrotherapy. | The advantages are adaptation, customization, hygiene, materials used, or environmental impact, among others. However, these products also have some disadvantages such as their price, initial investment and training, or manufacturing time. But it is convenient to give more reasons to make decisions that facilitate their application. In this sense, it is proposed as an improvement to provide splints or developed products with a characteristic that takes into account the initial sanitary use for which they were designed. The integration of different characteristics into a splint created by advanced manufacturing methods contributes to providing added value that can be a key decision point for its application. The use of functional splints in the immobilization period of musculoskeletal injuries can provide a reduction in costs, derived from the shortening of the rehabilitation period thanks to the advancement of the application of physiotherapeutic techniques applicable at this stage. In addition, the application of these techniques contributes to the prevention of muscular, articular, and vascular complications caused by the application of retention devices in this phase of treatment. |

For the last two steps, the Solidwork® and Excel® software were used to parameterize the design to consider the specific measurements of the patient extracted from the computed tomography of the same, the manufacturing was done on a Fab@home machine, with homemade silicone. The methodology can be implemented considering other more precise AM processes and bio-compatible materials. | The result is a stent form approved by doctors. In addition, a parameterization tool was used to modify the overall dimensions of the stent to fit a specific patient. Finally, the final conceptual design was printed using an additive manufacturing technology known as Fab@Home. | Combine and customize various well-known design techniques for their application in the development of tracheal endoprosthesis devices, a new approach to device development in the field of medicine. Other tracheal endoprosthesis devices are customized but not personalized because the design techniques used do not allow detailing the geometric characteristics at this level as the presented approach does. It meets two main requirements: a wavy D shape intended to prevent migration and a thickness of the back wall that can improve tracheal dynamics and prevent obstruction. However, future work is needed to validate the manufacturing technique, material biocompatibility, and the efficiency of the entire process. Consider packaging, sterilization, and labeling at an early stage as they are integral parts of the entire device. | Function | Avoid Migration The ideal would be for the stent to compress slightly once deployed. It should not migrate from its initial position. Migration frequently occurs as a result of insufficient stent diameter or due to tumor involution after treatment. In the trachea, in particular, displacements of up to 20% of cases can be observed if the stent has not been able to withstand. Stents with struts and partially covered metallic stents show lower migration rates than fully covered metallic stents. | A stent with a D-shaped form that resembles the natural geometry of the trachea, a reduced amount of material on the posterior wall that is in contact with the tracheal muscle wall, and a stent with rounded threads on each edge or ring. | There were 12 models after a brainstorming session in a group and the 12 designs were voted on. Manufacturing experts, designers, and doctors made the classification. Finally, only two models were selected. The design process followed an evolutionary approach with many iterations involving the opinions of customers (doctors/patients). Work was done on the final conceptual design until a satisfactory detailed design was produced. |

Consider packaging, sterilization, and labeling at an early stage as they are integral parts of the entire device. | Customization | Coincides with the patient's trachea. The stent should be adjusted to the patient for a better fit during insertion, as well as to avoid any possible migration during high expectoration. Once migration occurs, it is usually managed by extracting the migrated stent and replacing it with a new stent of a more appropriate size. Additionally, any contact pressure due to tumors can be reduced if migration is avoided by changing the position of certain stent features. The number of customization parameters should allow for proper matching between the stent and the trachea, but should not be too numerous in order to avoid complications in the automation of design. | Solidworks R linked with Excel software helped to automatically change the overall dimensions of the design for a particular patient. The selected customization parameters were those that fit the patient's trachea. The design parameters that could be modified were the stent height, internal stent diameter, external diameter, muscular wall thickness, and distance between rings. All the design rules and parameters were saved in the Excel file so that each user could modify them. Finally, with the customized stent parameters in the Excel file, a 3D stent model was created in Solidworks. | A list of attributes was made for the new stent design. They were obtained through interviews with doctors and visits to patients. Mainly, doctors provided detailed answers to the interview questions, but some patients also collaborated in this study and provided important information. Six hospitals collaborated in this study, and information was obtained from about 40 patients. Additionally, 30 doctors from these and other hospitals were interviewed to obtain a list of attributes. In general, the attributes given by the patients complement those proposed by the doctors. In this research, all attributes obtained from patients and doctors were considered equally. The attributes obtained from the interviews were supplemented with references in case not all attributes had been included. However, no other attributes were added apart from those obtained in the interviews. After the interviews, the attributes were translated back into real values that could be increased or decreased as needed. For example, 'dynamic' was expressed as reduced wall thickness. The design methodology for QFD quality was used to establish the customer's WHATs and the solution's HOWs, their respective evaluation, benchmarking of the competition, the level of correlation between the WHATs and HOWs, the positive and negative correlations of the HOWs; Third step, based on the negative correlations of the HOWs (contradictions in the technical aspects of the solution), use the TRIZ inventive problem-solving theory to establish technological solutions for materials and forms, in order to resolve the contradictions of the HOWs; Fourth step, verify if all customer requirements are met; Fifth step, evaluate the proposed solutions and select the best one. |

Easy to insert is defined as the ability of the stent to twist or adapt its shape to be inserted into a surgical instrument before an operation. Also, easy to remove is defined as the ease with which it can be removed from the body once it is no longer needed. Although both silicone and metal stents are easy to maneuver, a rigid bronchoscope often poses a serious obstacle for many endoscopists when it is necessary to quickly and effectively insert a silicone stent. The ideal stent should be removable, especially in cases of benign obstruction. In this sense, silicone stents are superior to metal stents. Metal stents cannot be easily removed because they adhere to the tracheobronchial wall within weeks. If complications arise, patients with metal stents often require multiple laser or electrocautery treatments to treat recurrent granulation caused by an irritating reaction to the metal. | An elastic modulus of 1-15 MPa is required to insert and remove a stent. | A list of attributes was made for the new stent design. They were obtained through interviews with doctors and visits to patients. Mainly, doctors provided detailed answers to the interview questions, but some patients also collaborated in this study and provided important information. Six hospitals collaborated in this study, and information was obtained from about 40 patients. Additionally, 30 doctors from these and other hospitals were interviewed to obtain a list of attributes. In general, the attributes given by the patients complement those proposed by the doctors. In this research, all attributes obtained from patients and doctors were considered equally. The attributes obtained from the interviews were supplemented with references in case not all attributes had been included. However, no other attributes were added apart from those obtained in the interviews. After the interviews, the attributes were translated back into real values that could be increased or decreased as needed. For example, 'dynamic' was expressed as reduced wall thickness.

| GME4 | Parametric customization and individualization. | 53 | This article presents a variety of product design processes for different levels of customization through the use of AM, from processes of elaborate individualization to specific product adaptation. | Basically, the article presents a methodology with 4 criteria for deciding whether to redesign parts of product series using AM (replacing parts produced with traditional manufacturing). 4 cases are presented. The criteria are: Integrated design, which means that there are multiple functions in one or few parts, allowing for a more compact product and a reduced number of parts; Individualization, or customization of parts that allows for meeting customer needs, which implies a greater variation in sizes, but to compensate for this, the parts are divided into standardized and customized ones, with the standardized ones still being manufactured using traditional methods, but the customized ones being manufactured using AM; Lightweight design, if the product is in motion or has dynamic applications, reducing the weight will improve performance; Efficient design, which means improving the product's efficiency in operation. | Examples of redesigned parts for AM are presented: medical device (reduction of parts), individualized pipe inspection element, lighter aerial support, among others. | Among the conclusions, it is highlighted that the redesign should not be focused on a single objective. | - | - | - | - | |
| GME4 | Parametric customization and individualization. | 83 | To contribute to the design of individualized products and answer the following research question: What processes can lead to design through the use of AM for customization? | A systematic literature review is carried out to examine existing approaches to implementing AM. The literature on design processes in custom design, the effects of production on the design phase, the use of AM in production, and the application of AM for customization was examined. After collecting the data, the types of design processes for customization through AM are concluded. The synthesis of the processes results, in particular, in adaptations of the processes of established design approaches. | Standardized individualization is recommended for personalization with AM for components where geometric individualization can increase customer satisfaction, comfort, or product applicability. It is recommended when the shape of the product can be adapted to individuals. It is useful if the contact surfaces are known and specific customer data can be measured. The process for a typical individualization case should be organized, standardized, and capable of automation. The source and type of data, limits of individual geometry, fabricability, and interfaces with other components are taken into account during the development of the recurring personalization process. Specific adaptation, the product can be adapted to customer desires within a fixed solution space or individual adaptations for design or engineering without changing the main attributes of the product or requiring a completely new engineering product. A product structure design for product adaptation is executed: an individualization scope is defined, enclosing the central product structure with customizable features and an open zone for individualization. The disadvantage of specific adaptation is the significant effort required in the structural and conceptual design of the preceding product, in which an independent spectrum of user-independent products and the basic potential of the product are developed. | Possible different customization strategies are possible. With attention focused on the influence in the design process, this document identifies a series of customization characteristics. Two types of customization were presented in the made-to-order manufacturing environment: standardized individualization, with a previous process development, resulting in a defined degree of customization for user participation; specific sample adaptation that the client desires influences the previous steps of the design process. Different levels of customer participation require different design methods and adaptation of individualization processes for differentiation in this field to make sense. It is emphasized that automated processes are required in the design of individualized products, with an emphasis on standards and programs, specific design methods are also required for customized products. | - | - | - | - | |

In a second stage, we move on to a quantitative analysis of the platform data, which indicates that remixing can lead to better design process outcomes in terms of quantity and diversity of designs. | The designers who take advantage of the remixing features are active in more categories and show less specialization than their non-remixing peers.

Remixing designers also create more designs per designer, providing strong evidence for the effectiveness of the remixing mechanism for speed. With regard to quality, a larger proportion of designs created by remixers are printed by community members.

| GME4 | Parametric customization and individualization. | tissue implant | ME24 | We demonstrate how to manufacture the mold of soft prostheses with a low-cost desktop 3D printer. | The manufacturing method used is known as Scanning Printing Polishing Casting (SPPC). First, the anatomy is scanned with a 3D scanner (kinet for Windows), then a tissue casting mold is designed on the computer (Rhinoceros V4.0 software) and printed in ABS with a desktop 3D printer (FFF). Subsequently, a chemical polishing method is used (with acetone, the heater is turned on, the container containing the acetone is heated to a temperature higher than the boiling point of acetone (56.5°C), as it is set to 80°C for the experiment. The heated acetone vapor rises from the container and washes the ABS sample, the acetone will no longer evaporate when the pressure inside the sealed container reaches its saturated vapor pressure. A simple equation (Ideal Gas State Equation) was used to calculate the reasonable volume of acetone) to polish the casting mold, removing the stair-step effect and acquiring a smooth surface. Finally, the last step is to melt medical-grade silicone into the mold (Silicone part A and part B (Dongguan Hongfeng Silicone Materials Co., LTD) were mixed in a 1:1 ratio (weight:weight) and stirred for 2 minutes, and then the mixture was degassed in a vacuum chamber for 10-15 minutes). After the silicone is cured, the soft prostheses can be removed from the mold. Using the SPPC method, soft prostheses with a smooth surface and complicated structure can be manufactured at a low cost. | Manufacture soft prostheses with the help of a desktop 3D printer. The printing costs of the negative mold were insignificant compared to traditional methods. In this report, a cheap and convenient method (SPPC) for manufacturing silicone prostheses is demonstrated. The staircase effect caused by the desktop 3D printer is eliminated. the translation may vary depending on the context and specific language nuances. | As an AI language model, I can help you with translation. Here is the translation of the provided data into English: As a result, the total cost of manufacturing the ear prosthesis is around S30, which is much lower than current methods of manufacturing soft prostheses. the translation may not be 100% accurate, as it is generated by an AI model. | - | - | - | - |
| GME4 | Parametric customization and individualization. | surgical instrument, instrument prototype | ME74 | This concept of custom surgical instruments was investigated as a pilot demonstration of mass customization and on-demand manufacturing by a team from the Naval Postgraduate Dental School (Bethesda, MD), Stratasys (Eden Prairie, MN), and the Defense Advanced Research Projects Agency (Arlington, VA) Service Chiefs Fellowship Program. Spring devices for custom orthodontic brackets and customized pivot pliers were digitally designed, manufactured, and evaluated using a surgical simulator. | The digital models of a spring clamp and a central pivot clamp were created in the SolidWorks 2012 computer-aided design (CAD) software. The models were parameterized with key dimensions (arm lengths, finger loop positions, etc.). Custom designs were generated simply by changing the values of the key dimensions within the CAD application. The instruments were sized to fit the hands of a clinician and tailored to express personal preferences and preferred technique. It was necessary to adapt the designs to accommodate the characteristics of currently available materials; this involved thickening the cross-sectional area of the clamp arms and redesigning the simple pivot hinges to provide the appropriate mechanical strength and rigidity. A Stratasys ABSi-Ag development material was used to print examples of the instruments. This material is currently being developed as a potentially biocompatible and bacteriostatic material for medical applications. Custom tissue forceps and a needle driver were designed, manufactured, and tested according to the physician's personal specifications. A subjective evaluation was performed by performing surgical procedures and suturing an incision on a surgical simulator of a cut suit. | A one-piece, spring-style tissue forceps design was created in CAD. The design was custom-made to fit the hand of a clinician, and later adapted in stiffness to provide the desired sensation with palm pressure. Interlocking triangular teeth were added to the tip of the instrument, according to the clinician's preference. Simple grip and hold tests were performed to evaluate the design; the information provided by the clinician led to further modifications. The stiffness of the arms, the length of the arms, and the angle of the arms in closure were modified at the request of the clinician. The change in the material deposition pattern in the material extrusion process affected the instrument's sensation as reported by the clinician. A two-piece hinge pivot forceps design was also created in CAD. A standard pivoting arm design, common to hemostats, was modified for production in ABS plastic. A 'T'-shaped pivot key and a tapered slot joined the arms. Handling dimensions included arm length, arm section, jaw length, jaw section, finger loop diameter, and position. The clinician expressed a desire for an instrument that could be picked up, manipulated, and dropped from a gloved hand with minimal manual articulation. The serrated jaws were sized for dissection and holding tasks. A closing zipper tooth was added to the back of the arm handles for closure; the zipper was operated by palm pressure. A basic surgery kit was printed on the FDM device, including tissue forceps, hemostat, and needle holders; the printing time was just over 6 hours. Successful laparotomy, ligation, splenectomy, and suturing were performed in the cutting suit using the custom instruments. | The instruments of spring and pivot pliers were designed according to the specifications of a clinical test, adapted to the dimensions of the hand, personal preference for the instrument's feel, and preferred surgical technique. The instruments were 3D printed on demand using a material extrusion 3D printer and then successfully used to complete surgical procedures on a realistic human simulator. With the development of new biocompatible materials for additive manufacturing, it will be possible to 3D print custom surgical instruments on demand. With design and manufacturing cycles of just a few hours, it will be feasible to quickly develop new instruments tailored to new surgical techniques and procedures. | - | - | - | - |

Previously, the effectiveness of sterilization of PLA with glutaraldehyde had been tested [ref. 11]. The sole extrusion temperature during manufacturing, which is 240°C, is sufficient to sterilize the instruments if combined with sterile conditions during manufacturing. Chemical sterilization left bacterial bodies on the instruments that were still detectable by the test, further research is required in that regard. |

Our 3D printer is available for $2199 and 1 kg of PLA is available for $27.99 including shipping. Since each retractor weighs 16 g, we can make 61 retractors/kg, which calculates to $0.46 of PLA per instrument. We would need to print 95 retractors to cover the cost of the printer and make each unit cost the same as the stainless steel version, $23.48. If our printer operated at 95% efficiency during the following week (168 h), the printer would pay for itself. Even if these instruments were used only once, they would still be less expensive than the cost of damage or theft of the steel instruments. In addition, 3D printers are quite durable. Our printer has completed a moderate 2000 h of printing without significant hardware failures and standard regular maintenance. If we were to spend the last 2.7 months, approximately 2000 h, printing retractors at 95% efficiency, we would have 950 retractors with a unit cost of $2.77. Not only does the low cost of this new technology make it accessible, but the potential cost savings can make it fiscally responsible. |

All samples were subjected to binary load testing using polymerase chain reaction (PCR) amplification of the V1-V2 region of the 16s rRNA gene as a measure of intact bacterial DNA. Briefly, 200 mL of sterile phosphate-buffered saline solution was added to each sample and vortexed. Two microliters of buffer were used as a template in a PCR consisting of 4 minutes at 98°C followed by 30 cycles of 98°C for 10 s, 68.8°C for 30 s, 72°C for 30 s. The PCR reagents were obtained from the Applied Biosystems real-time PCR master mix (Grand Island, NY) with 2 U of Phusion polymerase (New England Biolabs Incorporated, Ipswich, MA). The forward primer sequence was: AGAGTTT GATCMTGGCTCAG and the reverse primer sequence was: CYIACTGCTGCCTCCCGTAG. Two microliters of the resulting PCR product from each reaction were analyzed on an agarose gel to determine if an anticipated PCR product had formed. Negative controls consisting of purified water were included to monitor reagent contamination. A positive control containing Escherichia coli genomic DNA was included to demonstrate the success of the procedure. The sole extrusion temperature during manufacturing, which is 240°C, is sufficient to sterilize the instruments. If combined with sterile conditions during manufacturing, chemical sterilization left bacterial residues on the instruments still detectable by the test. Further research is required in this regard. |

Once the template is printed, the screw insertion site and its ideal trajectory are preoperatively confirmed. This resulted in an increase of over 20% in the rate of acceptable screws (reduction in pedicle cortex perforations). | Combination of reverse engineering and modeling. Commercial software for this process includes MIMICS, Ziostation, UG Imageware, and Freeform [45]. The guide template is placed on the posterior vertebra to guide the placement of the pedicle screw.

The objective of the demonstration was to show that, upon request, manufacturing in remote locations of a variety of sterile surgical instruments is a real possibility with current technology. | The following instruments were modeled in SolidWorks: Kelly Hemostat, needle holder, tissue forceps, retractor, scalpel handle, and Metzenbaum scissors. A parametric 3D CAD model was created and modified for each instrument based on adaptations of stainless steel instruments. Key dimensions were identified and then defined as driving dimensions. The team chose to follow an evolutionary design approach due to time constraints.

The instruments were printed in ABSi-Ag, a silver-loaded ABS plastic resin under development by Stratasys. Samples were tested for sterility by immersing them in 20 mL of autoclave-promoted microbial growth medium, tryptic soy broth. The devices were cultured overnight at 37°C on an orbital shaker (at 170 rpm) to promote microbial growth. The instruments were initially tested by dissecting and suturing fried chickens obtained from a local grocery store.

| GME5 | Surgical tools and prototypes | surgical instrument, instrument prototype | ME74 | This concept of custom surgical instruments was investigated as a pilot demonstration of mass customization and on-demand manufacturing by a team from the Naval Postgraduate Dental School (Bethesda, MD), Stratasys (Eden Prairie, MN), and the Defense Advanced Research Projects Agency (Arlington, VA) Service Chiefs Fellowship Program. Spring devices for custom orthodontic brackets and customized pivot pliers were digitally designed, manufactured, and evaluated using a surgical simulator. | The digital models of a spring clamp and a central pivot clamp were created in the SolidWorks 2012 computer-aided design (CAD) software. The models were parameterized with key dimensions (arm lengths, finger loop positions, etc.). Custom designs were generated simply by changing the values of the key dimensions within the CAD application. The instruments were sized to fit the hands of a clinician and tailored to express personal preferences and preferred technique. It was necessary to adapt the designs to accommodate the characteristics of currently available materials; this involved thickening the cross-sectional area of the clamp arms and redesigning the simple pivot hinges to provide the appropriate mechanical strength and rigidity. A Stratasys ABSi-Ag development material was used to print examples of the instruments. This material is currently being developed as a potentially biocompatible and bacteriostatic material for medical applications. Custom tissue forceps and a needle driver were designed, manufactured, and tested according to the physician's personal specifications. A subjective evaluation was performed by performing surgical procedures and suturing an incision on a surgical simulator of a cut suit. | A one-piece, spring-style tissue forceps design was created in CAD. The design was custom-made to fit the hand of a clinician, and later adapted in stiffness to provide the desired sensation with palm pressure. Interlocking triangular teeth were added to the tip of the instrument, according to the clinician's preference. Simple grip and hold tests were performed to evaluate the design; the information provided by the clinician led to further modifications. The stiffness of the arms, the length of the arms, and the angle of the arms in closure were modified at the request of the clinician. The change in the material deposition pattern in the material extrusion process affected the instrument's sensation as reported by the clinician. A two-piece hinge pivot forceps design was also created in CAD. A standard pivoting arm design, common to hemostats, was modified for production in ABS plastic. A 'T'-shaped pivot key and a tapered slot joined the arms. Handling dimensions included arm length, arm section, jaw length, jaw section, finger loop diameter, and position. The clinician expressed a desire for an instrument that could be picked up, manipulated, and dropped from a gloved hand with minimal manual articulation. The serrated jaws were sized for dissection and holding tasks. A closing zipper tooth was added to the back of the arm handles for closure; the zipper was operated by palm pressure. A basic surgery kit was printed on the FDM device, including tissue forceps, hemostat, and needle holders; the printing time was just over 6 hours. Successful laparotomy, ligation, splenectomy, and suturing were performed in the cutting suit using the custom instruments. | The instruments of spring and pivot pliers were designed according to the specifications of a clinical test, adapted to the dimensions of the hand, personal preference for the instrument's feel, and preferred surgical technique. The instruments were 3D printed on demand using a material extrusion 3D printer and then successfully used to complete surgical procedures on a realistic human simulator. With the development of new biocompatible materials for additive manufacturing, it will be possible to 3D print custom surgical instruments on demand. With design and manufacturing cycles of just a few hours, it will be feasible to quickly develop new instruments tailored to new surgical techniques and procedures. | - | - | - | - |

The selection of materials is done using a weighted average matrix and the final material is defined by verifying wedge stresses and deformations during surgery impact load and autoclave sterilization using finite element simulation.

| GME5 | Surgical tools and prototypes | Surgical guides | ME52 | Computer-assisted planning and patient-specific 3D printed instrumental guides provide excellent assistance for these two steps, respectively in correcting post-traumatic limb deformity (osteotomy). | At the end, the corrective closing wedge osteotomy was chosen. The authors believed that it was the one that could best improve the overall alignment of the lower limb, relieve pain, and preserve the remaining range of motion. Unnecessary complications of RTC could also be avoided. In view of the anticipated difficulties (fracture with previous implants), computer-assisted 3D planning was used with the help of computed tomography. The malformed femur (accident) was virtually reconstructed and the deformity was measured. Computed tomography images and 3D reconstructions of the contralateral limb were also obtained as mirror reference. From the surgeons' point of view, the technique required in the planning of the corrective osteotomy was similar to the traditional method. Deformities in the coronal and sagittal planes were corrected by two osteotomy cuts, while rotational deformity was corrected by rotation during the final opposition. Data including the apex, angle of the planned cuts, planned hinge, and translation were entered into the computer, which provided real-time virtual images of the corrected femur. These images allowed for easy adjustment of the planning. The planned cuts that generated the virtual image that most closely resembled the ideal alignment based on the contralateral limb image were the chosen cuts. The subsequent fixation with a locking plate was planned based on the corrected alignment of the femur (Figure 5). 3D models of the distal femur (both pre-osteotomy and post-osteotomy), the marking guide, and custom-made osteotomy guide models for the patient were 3D printed (Figure 6). The patient was placed under general anesthesia and positioned supine on a radiolucent drop table. Previous implants that would hinder subsequent procedures were removed and a lateral approach to the distal femur was performed. The 3D printed guide for bone resection and osteotomy was sequentially and temporarily fixed to the distal femur with multiple Kirschner wires (Kirschner wires). Subsequently, screw holes for definitive fixation were made and the bone was cut accordingly (Figure 7). The alignment of the femur was corrected by opposing the planes of the osteotomy, which was then fixed with a locking compression plate with pre-drilled screw holes through the guide before the osteotomy. Therefore, the cut bone surfaces would oppose each other and the alignment would be corrected according to preoperative planning by applying the plate and tightening the screws. During the application of the locking compression plate, it was observed that interfragmentary compression could not be achieved using the previously drilled screw holes, so a proximal screw was inserted into an eccentric hole to achieve axial compression at the site of the osteotomy. | Surgical uncertainty, subjective judgment, radiation exposure, and operation duration were reduced compared to traditional methods. Alignment was confirmed radiologically and clinically, after which autogenous and synthetic bone grafts were added as supplements. The operation proceeded smoothly and largely as planned, without surgery-related complications. *The patient was allowed to walk on the ground immediately after the operation for 4 weeks, followed by another 4 weeks of partial weight-bearing and then full weight-bearing. *At 7 months post-operation, the patient enjoyed a stable and pain-free left knee, with a static range of motion (10°-20°, same as preoperative range) and strength (4/5 according to the Medical Council Research scale, same as preoperative strength). They resumed walking without assistance and returned to their previous work. *Radiologically, progressive union and consolidation were observed in the osteotomy area (Figures S and 9). An 18° correction in varus malalignment and a 14° correction in flexion were observed on the X-rays. This alignment matched the preoperative planning and remained consistent throughout the union process. Due to the correction of alignment in the coronal and sagittal planes, the shortening of the left lower limb improved with a 1.5 cm increase in length. | In the past, corrective osteotomy planning was mainly based on 2D radiographs with the help of marking markers on transparencies. It was a difficult task even in the most experienced hands, especially in cases with multiplanar deformities due to the complexity of the correction. With these limiting factors, overall accuracy was often unsatisfactory. In summary, preoperative planning, intraoperative execution, postoperative rehabilitation, and recovery were smooth and the functional outcome was satisfactory. During the operation, surgeons encountered some difficulties in manipulating the two ends of the bone after osteotomies. In retrospect, we think that an osteotomy guide with better design or a greater number of guides could provide temporary stability and refine the operative steps. Pre-drilled locking screw holes also hindered the application of interfragmentary compression. We believe that this experience will help us fine-tune the planning in subsequent cases. Traditional alternatives for deformity correction, including the Ilizarov technique and the use of the Taylor spatial frame, remain irreplaceable. They provide an alternative for gradual correction of the deformity, especially in severe deformities where soft tissue tolerance is a major concern. In addition to recent advances in preoperative planning, intraoperative execution can now be assisted by computer-assisted surgery, which is often used in total knee arthroplasty and tumor resection. Theoretically, computer-assisted surgery improves the accuracy of bone cuts and shortens the operation time. With the popularization of 3D printing technology in orthopedic surgery, more precise and accurate operations are expected. 3D-printed patient-specific instrumentation (PSI) has great versatility of application. In our case, the proper application of the PSI guide was facilitated by the identification of a well-formed osteophyte, while stable fixation was achieved using multiple Kirschner wires. In cases where a reliable bony landmark is not available, computer navigation could be helpful. | - | - | - | - |

From the virtual model of the implant and its 3D printed model (FFF), rigid molds are designed and manufactured using 3D printing, and flexible molds are manufactured using flexible silicone molding. The selection of materials is done using a weighted average matrix, and the final size is defined by verifying stresses and deformations of the molds during implant manufacturing using finite element simulation. Subsequently, the implants were fabricated in PMMA and tested for fit with the printed bone model of the corrected skull. Software was developed to automate the design of rigid molds through 3D printing. | The implant made from the rigid mold had problems in demolding. The implant made from the flexible mold did not present any inconveniences in demolding, dimensionally complying with the tolerances and adjustments corresponding to the model of the corrected skull. The mold did not suffer any damage as predicted by the numerical simulations. A program was developed to automatically design the printed rigid mold based on the external measurements and the digital model of the implant.

In the case of standard implants, the size chosen by the surgeon does not adapt perfectly to the patient's biomechanics, and there will be a higher probability of bone resorption since this standard implant does not adequately transfer loads to the nearby bone tissue. Avoid manual adjustment of the standard implant during surgery. When deformed, the implant has been damaged as the material has undergone plastic deformation. This deformation produces local strengthening while reducing ductility, leading to a change in implant behavior. This is especially critical in long-term prostheses that support cyclic loads, as this plastic deformation can reduce fatigue and the overall durability of the implant. The implant has undergone a very damaging deformation equivalent to many cycles under normal conditions of use. The second drawback is that corrosion may occur because plastic deformation can break the passive layer of the contact area (pitting corrosion). |

In the case of a structural analysis, the solution shows a distribution in a three-dimensional map with the level of stress (strain, displacement, etc.) along the geometry. | Custom implants could reduce the negative effect of protection against stress. Shielding against stress refers to the reduction of bone density (osteopenia) as a result of the elimination of normal bone stress by an implant (e.g., the femoral component of a hip prosthesis). According to Wolff's law (Wolff, 1986), the bone of a healthy person or animal remodels in response to the loads it is subjected to. Therefore, if the bone load decreases, the bone will become less dense and weaker because there is no stimulus for the continuous remodeling required to maintain bone mass. During the custom implant design process, shielding against stress can be taken into account and minimized through different designs and structural FEA analysis to achieve. |

| GME6 | Implants | - | ME38 | Three-dimensional printing (3DP) is gaining increasing recognition as a technique that will transform the landscape of surgical practice. It allows for the rapid conversion of anatomical images into physical objects, which are being used across a variety of surgical specialties. It is not clear which groups are leading the way in finding novel ways to use the technology and what the technology is specifically being used for. The aim of this article was to review the current applications of 3DP in modern surgical practice. | A electronic search was conducted in MEDLINE, EMBASE and PsycINFO for terms related to 3DP. These were then examined for their relevance and the practical applications of the technology in surgery. | Results: Initially, 488 articles were found, and these were finally reduced to 93 full-text articles. It was determined that there were three main areas in which technology is being used for printing: (1) anatomical models, (2) surgical instruments, and (3) implants and prostheses. | The different specialties are at different stages in the use of technology. The costs of implementing technology and the time it takes for printing are important factors to consider before widespread use. In the foreseeable future, it is an exciting and interesting technology with the ability to radically change healthcare and revolutionize modern surgery. | - | - | - | - |
| GME6 | Implants | - | ME53 | In recent years, the use of three-dimensional printing (3DP) technology has gained momentum in spinal orthopedic surgery. Although research on this topic is still mainly limited to case reports and small cohort studies, it is evident that there are many avenues for 3DP innovation in the field. This review article aims to examine the current and emerging applications of 3DP in spinal surgery, as well as the challenges of 3DP production and the limitations of its use. | Literature review | The models of 3DP have been presented as useful tools for patient education, medical training, and preoperative planning. Intraoperatively, 3DP devices can serve as guides and surgical implants for the specific patient that improve surgical outcomes. However, the time, cost, and learning curve associated with building a 3DP model are significant barriers to its widespread use in spinal surgery. | Considering the costs and benefits of 3DP along with the various risks associated with different spinal procedures, 3DP technology is likely most valuable for complex or atypical cases of spinal disorders. Further research is justified to better understand how 3DP can and will impact spinal surgery. | - | - | - | - |
| GME6 | Implants | tissue implant | ME24 | We demonstrate how to manufacture the mold of soft prostheses with a low-cost desktop 3D printer. | The manufacturing method used is known as Scanning Printing Polishing Casting (SPPC). First, the anatomy is scanned with a 3D scanner (kinet for Windows), then a tissue casting mold is designed on the computer (Rhinoceros V4.0 software) and printed in ABS with a desktop 3D printer (FFF). Subsequently, a chemical polishing method is used (with acetone, the heater is turned on, the container containing the acetone is heated to a temperature higher than the boiling point of acetone (56.5°C), as it is set to 80°C for the experiment. The heated acetone vapor rises from the container and washes the ABS sample, the acetone will no longer evaporate when the pressure inside the sealed container reaches its saturated vapor pressure. A simple equation (Ideal Gas State Equation) was used to calculate the reasonable volume of acetone) to polish the casting mold, removing the stair-step effect and acquiring a smooth surface. Finally, the last step is to melt medical-grade silicone into the mold (Silicone part A and part B (Dongguan Hongfeng Silicone Materials Co., LTD) were mixed in a 1:1 ratio (weight:weight) and stirred for 2 minutes, and then the mixture was degassed in a vacuum chamber for 10-15 minutes). After the silicone is cured, the soft prostheses can be removed from the mold. Using the SPPC method, soft prostheses with a smooth surface and complicated structure can be manufactured at a low cost. | We proposed to manufacture soft prostheses with the help of a desktop 3D printer and achieved this goal. The printing costs of the negative mold were insignificant compared to traditional methods. This report demonstrates a cheap and convenient (SPPC) method of silicone prosthesis manufacturing. The stair-step effect caused by the desktop 3D printer is eliminated. | As an AI language model, I can help you with translation. Here is the translation of the provided data into English: As a result, the total cost of manufacturing the ear prosthesis is around S30, which is much lower than current methods of manufacturing soft prostheses. the translation may not be 100% accurate, as it is generated by an AI model. | - | - | - | - |
| GME6 | Implants | Bone implant | ME25 | The purpose of this work is to investigate the use of medical-grade polymethyl methacrylate (PMMA) in fused deposition modeling (FDM) for manufacturing customized freeform porous structures for various applications, including craniofacial reconstruction and orthopedic spacers. It also aims to examine the effects of different manufacturing conditions on the porosity and mechanical properties of PMMA samples. | The parameters for construction and procedures for properly and consistently extruding PMMA filament in FDM to build 3D structures were determined. Two experiments were conducted to examine the effects of different manufacturing conditions, including the cleaning frequency of the nozzles, layer orientation, and air gap (AG) (or distance between filament edges) on the mechanical properties and porosity of the fabricated structures. The samples were characterized using optical micrographs, and measurements of sample weight and dimensions were used to calculate porosity. The yield strength, deformation, and modulus of elasticity of the samples were determined through compression tests. | The results show that both the cleaning frequency of the tip (cleaning after every layer or cleaning after every ten layers) and the orientation of the layers (transverse or axial with respect to the applied compression load) used to manufacture the scaffolds have effects on the mechanical properties and resulting porosity. Samples manufactured in the transverse orientation with high frequency of cloth at the tip have higher compression strength and higher modulus than samples with low frequency of cloth at the tip (compression strength: 16 ^ 0.97 vs 13 ^ 0.71 MPa, modulus: 370 ^ 14 vs 313 ^ 29 MPa, for high vs low frequency of cloth at the tip, respectively). Additionally, samples manufactured in the transverse orientation have higher compression strength and modulus than those manufactured in the axial orientation (compression strength: 16 ^ 0.97 vs 13 ^ 0.83 MPa, modulus: 370 ^ 14 vs 281 ^ 22 MPa; for samples manufactured with one cloth per layer in the transverse and axial orientations, respectively). Overall, stiffness and yield strength decreased as porosity increased (compression strength: 12 ^ 0.71 to 7 ^ 0.95 MPa, modulus: 248 ^ 10 to 165 ^ 16 MPa, for samples with porosity ranging from 55 to 70 percent). As a demonstration, FDM is successfully used to manufacture patient-specific three-dimensional PMMA implants with variable densities, including the repair of cranial defects and femur models. | The necessary construction parameters for the successful manufacturing of FDM with medical grade PMMA filament (1/1600Ø) were developed using an FDM 3000. It was found that a liquefaction temperature and a wrap temperature of 235C and 55C, respectively, as well as a 60 percent increase in the model feed rate, were necessary to properly and consistently extrude the PMMA filament. Structures with different porosities and manufacturing conditions (tip scanning frequency and layer orientation) were produced, and their compression mechanical properties were examined. The results showed that both the tip cleaning frequency (cleaning every layer or every ten layers) and the layer orientation (transverse or axial with respect to the applied compression load) used to manufacture the structures, as well as the porosity (50-70 percent) of the structure, had an effect on the mechanical properties. Overall, the compression strength results of the porous PMMA structures manufactured (seven to 16 MPa, with a porosity of 50-70 percent) were in the range of trabecular bone (three to 15 MPa with a porosity of 70-90 percent). It is expected that as the porosity of the manufactured samples decreases, the compression strengths will approach those of molded PMMA bone cement (85-100 MPa), allowing for properties closer to cortical bone (130-180 MPa). Like other AM technologies, FDM allows for the ability to rapidly manufacture complex geometries with controlled architectures, and in the present case, the processing of PMMA in FDM will allow for the direct manufacturing of a variety of medical implants from medical imaging data. To demonstrate the success of manufacturing patient-specific PMMA 3D FDM models with variable densities, a model of a structure to repair a cranial defect and a model of a femur were manufactured. Implants for cranial repairs can be directly manufactured in FDM from medical imaging data and are designed with specific and controlled porosities. This methodology represents an alternative to the current use of PMMA in cranial reconstruction. The demonstrations showed the possibility of using FDM for the direct manufacturing of customized PMMA structures with variable and controlled porosities, and therefore adapted mechanical properties. Many additional opportunities will be enabled when this work is expanded to other biocompatible thermoplastic materials such as polypropylene, polycaprolactone, polyethylene, and other derived compounds that can be used to enhance mechanical properties and bioactivity. | Function | Use of PMMA filament for the design and manufacture of patient-specific implantable 3D models to repair cranial defects can be directly fabricated in PMMA from medical imaging data.

These spacers preserve the tension of soft tissues and reduce dead space at the fracture site, and PMMA material can be combined with antibiotics to provide local antibiotic delivery and fight infection (Eufinger et al., 1995; Frutos Cabanillas et al., 2000; Pelletier et al., 2009). |

It is expected that as the porosity of the manufactured samples decreases, the compression strengths will approach those of molded PMMA bone cement (85-100 MPa), allowing for properties closer to cortical bone (130-180 MPa). Like other AM technologies, FDM allows for the ability to rapidly manufacture complex geometries with controlled architectures, and in the present case, the processing of PMMA in FDM will allow for the direct manufacturing of a variety of medical implants from medical imaging data.

Experiment I analyzed the effect of tip rubbing frequency and construction orientation on the mechanical properties of the fabricated structures, while Experiment II evaluated the mechanical properties of samples with different porosity percentages. Each experimental condition consisted of six samples of square prisms with design dimensions of 7 x 7 x 13.5 mm. The scaffold structures were designed with a raster width of 0.406 mm, an SH of 0.254 mm, and a raster angle of 0°/90°. Air gap was varied to achieve different ranges of porosity. | Compression tests were performed on an Instron 5866 system (Instronw, Norwood, Massachusetts) following the guidelines provided in Zein et al. (2002) based on ASTM F451-08 standard. A 10 kN load cell was used, and a crosshead deformation rate of 1 mm/min was applied. Compression stress calculations were performed by dividing the applied force by the cross-sectional area of the original specimen. Strain was defined as the ratio of axial deformation to the height of the original sample. Compression stress-strain graphs were created from which various mechanical properties were obtained. Compressive yield strength was defined as the stress after which the initial linear region deviated from linearity; yield strain was defined as the stress associated with the compressive yield strength. Stiffness was defined as the elastic modulus, E, and was calculated from data representing the slope of the initial linear region. For all experiments, student t-tests were performed to compare the mean values of independent samples with a significance level of 0.05. Additionally, an ANOVA was conducted for the specimens used in Experiment II to compare the mean values of RW from six independent samples with a significance level of 0.05. The data shown in the graphs represent the means ± standard deviation. P values less than 0.05 were considered significant. The specimens for Experiment II were observed and imaged using a stereomicroscope (Leica MZ16, Leica Microsystems, Inc., Bannockburn, Illinois) equipped with a CCD camera (Retiga 2000R Fast 1394, QImaging Corp., Canada). Measurements for RW, AG, and SH were taken from digital images. Multiple images were captured to obtain at least five measurements per dimension per sample. |

It was found that a liquefaction temperature of 235°C had the best mesh surfaces and minimal evidence of material residue for this wrapping temperature. Various wrapping temperatures were tested and it was found that 55°C was the best for minimizing material residue and improving mesh surfaces. Material feed rates were determined by running the default calibration method provided by Insight V3.5 cutting software (Stratasys, Inc.) until the appropriate raster widths corresponding to the diameter of the extrusion tips were achieved. | Through a trial and error process, different parameters of bed temperature, extruder temperature, and feed rate were tested: FDM extrusion mainly depends on the temperature of the liquefier, the temperature of the enclosure, and the feed rate of the material. Simple square prisms with T16 tips were fabricated, with an enclosure temperature of 75°C and various liquefaction temperatures, while closely monitoring the construction process. Relatively low temperatures, 180-210°C, failed to properly extrude PMMA as the filament would audibly break before entering the liquefiers. A temperature of 225°C allowed for the extrusion of PMMA but created extremely rigid rasters that did not adhere properly to the support material (ABS P400 R), causing the models to detach before being properly completed. Higher temperatures around 270°C created grids with visible wavy surfaces and caused excessive material residues that affected the geometry. Additionally, an excess of material flowed from the extrusion tips while the FDM system was not being constructed. |

The section of the skull damage was selected using CAD software (PowerSHAPE, Delcam, UK) that allows for the manipulation of triangular meshes. From the definition of the contour of the lesion, the patient's head wireframe was drawn and used as a reference to establish the curvature of the implant, which became its external surface. Then, the thickness of the implant was established using the conical surface procedure (Min and Dean, 2003). This gradual decrease method comprises, first, the generation of a surface; second, an internal surface is added, which is smaller and parallel to the external one. Finally, both surfaces are merged, creating a third one that will be in contact with the skull. Each design parameter was determined by the specific anatomy of the patient. In addition, the implant CAD was evaluated to ensure its assembly to the patients' anatomy. For this purpose, both the implant and the lesion were manufactured in polycarbonate using the FDM 400 mc Stratasys machine. The next step in this manufacturing process was the design of the mold that would replicate the implant's geometry. To simplify the mold design process, a model lesion was studied and its corresponding mold was designed in CAD. A two-piece core and cavity mold was created by extruding the CAD model of the implant from a solid rectangular prism, resulting in a hollowed block that adopts the shape of the implant. The parting line was defined, considering that the central part of the mold contains 100% of the required thickness of the implant to apply pressure to the mold cavity. This consideration was made to avoid trapped air and therefore the appearance of porosity in the implant. At this stage of the process, the 3D-CAD data of the mold is ready to be manufactured. |

Although there are custom-made cranial prostheses available in the market with high technological level and cutting-edge materials, they are not always accessible to the general population in developing countries. | Computed tomography data was used to create a three-dimensional (3D) model of the patient's lesion by reconstructing Digital Imaging and Communications in Medicine (DICOM) images into a Standard Tessellation Language (STL) file, which was then used to design the corresponding implant using CAD software. Consequently, a two-piece core and cavity molds were also designed to replicate the implant's geometry in CAD. The 3D-CAD data was sent to an Additive Manufacturing (AM) machine, and the molds were fabricated using polycarbonate as a thermoplastic material. A reactive mixture was poured into the molds to produce PMMA directly, and it was allowed to polymerize until cured. Finally, a clear case study of a bubble-free PMMA implant was obtained. | The manufacturing of CAD-designed molds with AM, replacing the production of the injury model, resulted in a 45% reduction in the manufacturing time of PMMA. Additionally, the implant showed a better fit than that produced by the conventional process. The use of AM molds for the manufacturing of PMMA implants has demonstrated a reduction in waiting time, which potentially can reduce patients' waiting time. | The joint use of CAD technology and FDM as an AM method to produce molds for PMMA implants for cranio-maxillofacial reconstruction seems to have many advantages, as it replaces several steps in the production of conventional PMMA implants, opening the possibility of minimizing dimensional errors due to handling. The use of polycarbonate molds manufactured with FDM for the direct manufacturing of PMMA implants, in the reported clinical case study, reduces the waiting time from 5 weeks (including delays in third-party services and the time needed for the patient to obtain economic resources) to 15 hours (a time reduction of 45.5% compared to the process currently used by HGM), which potentially can reduce the waiting time for patients being treated at the General Hospital of Mexico 'Dr. Eduardo Liceaga'.

Displacement and stress analysis were performed using finite element analysis software (SolidWorks, Dassault Systèmes SolidWorks Corporation, USA), applying a pressure of 220 KPa on a polycarbonate assembly of 100-100 mm [Figure 6(b)], which represents the size of the mold for this case study. The tensile strength and tensile modulus of the polycarbonate reported by the manufacturer are 68 and 2,300 MPa, respectively. The objective of this analysis was to determine the minimum thickness of the mold required to achieve a maximum deformation of 80 m at its center, which was 12.5 mm. | A static analysis of the mold assembly was carried out to determine that the applied pressure would not break or deform the polycarbonate mold.

The PMMA used for the manufacture of the implants was a commercial radiotransparent two-component bone cement (NicTon, Mexico). Polyvinyl alcohol (PVA) was used as a separation medium. | The material selection for the FDM-manufactured mold was based on the maximum temperature that the PMMA polymerization reaction can reach. Vallo (2000) reported a maximum temperature of 131.79°C for commercial PMMA bone cement with a cement thickness of 8 mm; in this study, the average implant thickness was 7.4 mm. Polycarbonate was the chosen model material within the available Stratasys Fortus 400 mc, as it has a heat deflection temperature of 138°C and is also chemically resistant to methyl methacrylate monomer. The mold was fabricated using breakaway support material (PCS) and a layer height of 0.254 mm (T16). The powder component consisted of PMMA powder, initiator (benzoyl peroxide), and other elements such as plasticizers, opacifiers, and pigments. Consequently, the liquid component was methyl methacrylate monomer, which may also include crosslinkers and stabilizers (Lee et al., 2002). The volume ratio used in the PMMA casting formulation was 2:1 powder/liquid. Polyvinyl alcohol (PVA) was used as a release medium. Each mold part was immersed in PVA for 1 minute, and the film was air-dried at room temperature (25°C) for 45 minutes. This procedure was repeated five times to achieve a homogeneous film with a thickness of 0.17 ± 0.02 mm, which was measured using a digital thickness gauge (model 700-118, Mitutoyo, Japan). Additionally, 15 ml of PMMA reaction mixture was prepared at room temperature and hand-mixed for 30 seconds. The reactive mixture was poured into the molds and closed with a 'C'-shaped clamp; two metal plates were placed between the clamp and the mold to evenly distribute the applied force. The molds containing the PMMA mixture were placed in an oven at 90°C for 3 hours. Once the curing time was completed, the PMMA pieces were manually removed from the mold and polished. |

The integration of this manufacturing process into the production of PMMA implants for craniofacial reconstruction reduced the production time of PMMA implants by decreasing the number of steps from six to four. The production time of the implant for the case study was five weeks by the traditional method and 15 hours by the mold-based manufacturing process produced with AM.

The technological progression of 3D printing can further improve wound healing by creating larger skin patches and covering wider areas of the wounds with the hope of being used in future clinical trials. New advancements will require new biomaterials, optimization of scaffold design, and a better understanding of cell functioning. 3D printing technology is also a promising and developing approach for polymer processing and manufacturing of cardiovascular stents. The application of 3D printing aids in the structural design process for stent manufacturing, ultimately influencing the technical properties of the stents. Biocompatible materials with the right balance between mechanical properties and degradation rate are still needed. The fields of otorhinolaryngology and dentistry were the first to implement 3D technology in their manufacturing methods; this technology has allowed them to produce customized hearing aids and dental aligners in a serial production. In addition to these two medical devices already on the market, there are several 3D printed implants such as the trachea, ear, and nose replacements that have already been implanted in humans and have shown promising results.

Facilitate location during medical check-ups. | The first layer of the Absorb stent is composed of poly (L-lactide), which serves as the base polymer, and has the shape of a tube with zigzag rings connected by bridges. The next layer is a drug mixture, poly(D, L-lactide) (PDLLA), which serves as the drug-releasing layer, and then, on top, additional features are included such as a pair of radiopaque platinum markers that aim to assist in locating the stents during angiography and the balloon delivery system. | The implanted stent keeps the artery open, allowing blood to reach the heart. However, the placement of the stent in the coronary artery can cause injury to the vessel, triggering the formation of neointimal tissue inside the stent and an inflammatory response, leading to restenosis (recurrent narrowing of the coronary artery). As a result, repeated procedures are required, which are often associated with decreased patient well-being and increased healthcare costs (Kleinedler et al., 2012). To address this problem, advances have been made in the development of stents, including drug-eluting stents, polymeric stents, and stent manufacturing methods (Ramadugu and Latha Alikatte, 2016; Foerster et al., 2016). |

The latest advances in 3D printing of artificial skin are described, with a focus on the treatment of burn wounds. The chapter also examines the methods and materials being used for 3D printing of stents, including computer-printed metal, biodegradable polymers, self-expanding stents, and drug-eluting stents. Otorhinolaryngology is a specialized area where AM has also been successfully used for implant manufacturing. Examples of implants, such as hearing aids that are already on the market, and 3D printing techniques that can be used to create implants to replace middle ear bones (ossicles) when damaged or to reconstruct the entire ear, are examined. Finally, dental implants in the research and development stage are reviewed. | Literature review | The application of 3D printing for the manufacturing of skin substitutes for wound treatment has proven to be effective and has accelerated the healing processes. The ability to create multiple complex geometries and use a wide range of biomaterials and cells has great value for skin manufacturing. The technological progression of 3D printing can further improve wound healing by creating larger skin patches and covering wider areas of the wounds with the hope of being used in future clinical trials. New advancements will require new biomaterials, optimization of scaffold design, and a better understanding of cell functioning. 3D printing technology is also a promising and developing approach for polymer processing and manufacturing of cardiovascular stents. The application of 3D printing aids in the structural design process for stent manufacturing, ultimately influencing the technical properties of the stents. Biocompatible materials with the right balance between mechanical properties and degradation rate are still needed. The fields of otorhinolaryngology and dentistry were the first to implement 3D technology in their manufacturing methods; this technology has allowed them to produce customized hearing aids and dental aligners in a serial production. In addition to these two medical devices already on the market, there are several 3D printed implants such as the trachea, ear, and nose replacements that have already been implanted in humans and have shown promising results. Clinical trials are currently being conducted to demonstrate the safety and efficacy of these implants in order to comply with all regulations. | Although the application of 3D printing in the biomedical field has reached the market for the aforementioned applications, the technology is still in the development process. Ongoing research seems promising to make it used as a standard manufacturing method in both clinics and industry. | Material | Ears (external implant): It must be a biocompatible material, It must be a strong, hard and water-resistant material like ABS. | While the LS seemed more promising as it used nylon. In 2002, a biocompatible material developed by Dreve materials in Germany suitable for SLA became available, and the hearing aid company Widex (https://www.widex.es/audifonos/tipos#formato) began implementing this technology. The material was a resin composed of a monomeric dimethacrylate, a urethane methacrylate, an aliphatic monomeric dimethacrylate, and the photoinitiator (Klare et al. 2004).

A post-processing step of spray coating and immersion coating has been included in the process to smooth the stent surface and allow for the incorporation of drugs in the future. Another 3D printing technique that has been investigated for stent manufacturing is extrusion. Park et al. (2015) successfully produced bioresorbable and drug-eluting PCL stents using this technique. Cabrera et al. (2017) fabricated a cardiovascular stent using FDM. Computer-designed stents were manufactured using a commercially available copolyester polymer that has been shown to biodegrade through hydrolysis. | After printing (extrusion), the stent was coated with the immunosuppressive drug followed by implantation in the artery and no complications were indicated. By optimizing the process parameters, it was possible to adjust the geometry of the stents, including the diameter, width, and thickness of the stent. The resulting mechanical properties were similar to those of nitinol stents. |

Clinical trials are currently being conducted to demonstrate the safety and efficacy of these implants in order to comply with all regulations. | Although the application of 3D printing in the biomedical field has reached the market for the aforementioned applications, the technology is still in the development process. Ongoing research seems promising to make it used as a standard manufacturing method in both clinics and industry. | Costs and deadlines | Increase production speed, reduce medical check-ups. Settling times similar to conventional ones. | Invisaling uses digital dentistry and SLA technology to manufacture around 220,000 aligners per day, almost 8 million per year (McCue 2017). Infrequent check-ups at the clinic. Usually once every 3 months. On average, Invisalign treatment lasts from 4 months to 1.5 years. It depends on the complexity of the case and, consequently, the type of Invisalign system used. Prices range from 2266 to 3690 USD. | A study conducted at Texas A&M University showed that there were no significant differences at any time between the two methods, indicating that lnvisalign and traditional appliances may have similar treatment outcomes, as well as similar settling during 6 months of retention (Preston 2017). |

The chapter examines recent advances in 3D printing technologies for biomedical implants. The latest advances in 3D printing of artificial skin are described, with a focus on the treatment of burn wounds. The chapter also examines the methods and materials being used for 3D printing of stents, including computer-printed metal, biodegradable polymers, self-expanding stents, and drug-eluting stents. Otorhinolaryngology is a specialized area where AM has also been successfully used for implant manufacturing. Examples of implants, such as hearing aids that are already on the market, and 3D printing techniques that can be used to create implants to replace middle ear bones (ossicles) when damaged or to reconstruct the entire ear, are examined. Finally, dental implants in the research and development stage are reviewed. | Literature review | The application of 3D printing for the manufacturing of skin substitutes for wound treatment has proven to be effective and has accelerated the healing processes. The ability to create multiple complex geometries and use a wide range of biomaterials and cells has great value for skin manufacturing. The technological progression of 3D printing can further improve wound healing by creating larger skin patches and covering wider areas of the wounds with the hope of being used in future clinical trials. New advancements will require new biomaterials, optimization of scaffold design, and a better understanding of cell functioning. 3D printing technology is also a promising and developing approach for polymer processing and manufacturing of cardiovascular stents. The application of 3D printing aids in the structural design process for stent manufacturing, ultimately influencing the technical properties of the stents.

| GME7 | Tissue engineering | Scaffolding for fabric. | ME8 | Here is the translated data in English: We present a new technique for manufacturing double-pore scaffolds for various tissue engineering applications, in which 3D printing of poly(vinyl alcohol) (PVA) filament mold is combined with salt leaching process to control the geometry and dimensions of structured and random pores, respectively. | The sacrifice molds for structured and double-pore scaffolds were 3D printed using a Replicator 2X 3D filament deposition printer (MakerBot Industries, LLC, Brooklyn, NY, USA). In summary, a 3D cube (L 25 mm × W 25 mm × H 10 mm) was designed using SolidWorks 2013 CAD 3D design software (Dassault Systems, SolidWorks Corp., Waltham, MA, USA). The design was exported in STL format to the 3D printing software (Makerware 2.4.1) for G-code generation and mold printing. Poly(vinyl alcohol) (PVA) soluble in water filaments (MakerBot, USA) were used to print the sacrificial molds. The printing was done at 200 °C nozzle temperature and 40 °C bed temperature. PVA molds with various porosities (fillers) were used directly for the fabrication of structured pore scaffolds. For the fabrication of double-pore scaffolds, PVA molds were printed with 40% filler. 10 g of NaCl crystals (Sigma-Aldrich Corporation, St. Louis, MO, USA) (size 300-600 μm) were mixed with 1 ml of ultrapure water from a Milli-Q® water purification system (Millipore Corporation, Billerica, MA, USA) and manually packed into the PVA mold. The salt-filled molds were dried in an oven at 60 °C for 1 h. The small amount of water was used to form interconnections between the salt crystals, as well as between the salt crystals and the PVA filaments. Both PVA molds for structured pore scaffolds and salt-PVA molds for double-pore scaffolds were replicated in polydimethylsiloxane (PDMS) (Sylgard 184 elastomer kit, Dow Corning Corporation, Midland, MI, USA). The PDMS base was thoroughly mixed with the curing agent in a ratio of 10:1 and the mixture was degassed in a vacuum desiccator to remove air bubbles. The PDMS mixture was then poured into the mold, and the container with the mold covered with the PDMS mixture was transferred to the vacuum desiccator for 2-3 h to ensure complete infiltration of PDMS into the mold. The PDMS was cured at 60 °C in an oven for 4-6 h. After curing, the excess PDMS around the molds was removed to expose the PVA or salt-PVA structures. This was done to allow subsequent dissolution of PVA and salt in water. The complete PDMS structures of the molds were immersed in water until the PVA and salt were completely removed (around 6-12 h), releasing the PDMS scaffolds with structured or double-pore architecture. Various physical and mechanical properties of the double-pore scaffolds were compared with control scaffolds with only structured or only random pores, fabricated using previously reported methods. | The scaffolds with double pores showed intermediate mechanical properties compared to scaffolds with structured and random pores. The compression modulus of the structured pore scaffolds was similar to that of our previous study presented with similar type scaffolds. The result of the mechanical test indicates that the mechanical properties of the double pore scaffolds can be easily modified by combining random and structured pores. Since the elastic moduli of human organs and tissues are very diverse, the stiffness of the fabricated double pore PDMS scaffolds can be adjusted by changing the porosity of the scaffolds or the degree of crosslinking, i.e., the ratio between the PDMS base and the curing agent [36]. As mentioned earlier, the manufacturing technique presented in this document can be applied to other materials besides PDMS, such as the biomaterial PCL (supplementary material Fig. S5), which provides an additional way to fine-tune the stiffness of the scaffolds according to the needs of in vivo tissues. The double pore scaffold with highly interconnected structured pores combined with adjacent random pores was superior to the other two types of scaffolds as it combines a high number of cells, metabolic activity, and albumin secretion with a uniform distribution of live cells throughout the scaffold volume. | A method for manufacturing double-pore scaffolds by combining 3D filament printing of a water-soluble sacrificial PVA mold for the primary structured pores and salt leaching to create random pores within the bulk scaffold. The method allows for control of pore geometry and dimensions, as well as the mechanical stiffness of the structured and random pores of the double-pore scaffold. Using PDMS as the scaffold material, the manufacturing process was demonstrated to be fast, inexpensive, and scalable for generating scaffolds of a size relevant to thick tissues. Sacrificial molds printed with PVA can also be used with different biodegradable natural polymers (e.g., gelatin and silk) combined with lyophilization to provide scaffolds with a wide range of mechanical properties. Human hepatoblastoma cells (HepG2) were cultured on different types of scaffolds for 16 days, monitoring their adhesion, distribution, proliferation, viability, metabolic activity, and albumin secretion, and cells were cultured on double-pore scaffolds with cells cultured on scaffolds with only structured or only random pores. The double-pore scaffold with highly interconnected structured pores combined with adjacent random pores was superior to the other two types of scaffolds as it combines a high number of cells, metabolic activity, and albumin secretion with a uniform distribution of live cells throughout the scaffold volume. In conclusion, the described manufacturing technique is fast, inexpensive, scalable, and compatible with different polymers, making it suitable for engineering various organs/tissues on a large scale. | Function | Manufacture double-pore scaffolding for tissue engineering, with controllable pore size, uniform and random distribution, and interconnection, all in as automated a process as possible. | 3D printing of a poly(vinyl alcohol) (PVA) mold is combined with the salt leaching process. | In this technique, the sacrificial PVA mold, which determines the architecture of the structured pores, was filled with salt crystals to define the regions of random pores of the scaffold. After crosslinking the melted polymer, the combined PVA and salt mold was dissolved in water. The dual-pore scaffold is superior to the other two types of scaffolds as it combines a high number of cells (Fig. 5A), metabolic activity (Fig. 5B), and albumin secretion (Fig. 5C) with a uniform distribution of live cells both in (Fig. 6C) and in the scaffolds (Fig. 7C). |

The method allows for control of pore geometry and dimensions, as well as the mechanical stiffness of the structured and random pores of the double-pore scaffold. Using PDMS as the scaffold material, the manufacturing process was demonstrated to be fast, inexpensive, and scalable for generating scaffolds of a size relevant to thick tissues. Sacrificial molds printed with PVA can also be used with different biodegradable natural polymers (e.g., gelatin and silk) combined with lyophilization to provide scaffolds with a wide range of mechanical properties. Human hepatoblastoma cells (HepG2) were cultured on different types of scaffolds for 16 days, monitoring their adhesion, distribution, proliferation, viability, metabolic activity, and albumin secretion, and cells were cultured on double-pore scaffolds with cells cultured on scaffolds with only structured or only random pores. The double-pore scaffold with highly interconnected structured pores combined with adjacent random pores was superior to the other two types of scaffolds as it combines a high number of cells, metabolic activity, and albumin secretion with a uniform distribution of live cells throughout the scaffold volume. In conclusion, the described manufacturing technique is fast, inexpensive, scalable, and compatible with different polymers, making it suitable for engineering various organs/tissues on a large scale. | Dimensions | Distances of channels ranging from 78 μm to 1482 μm, interconnected pores, pores of size between 300-600 um. | A cube was designed in 3D (L 25 mm × W 25 mm × H 10 mm) using the CAD 3D design software SolidWorks 2013 (Dassault Systems, SolidWorks Corp., Waltham, MA, USA). PVA molds printed with various porosities (fillers) were directly used for the fabrication of structured pore scaffolds. For the fabrication of double-pore scaffolds, PVA molds were printed with a 40% filler, 10 g of NaCl crystals (Sigma-Aldrich Corporation, St. Louis, MO, USA) (size 300-600 μm) were mixed with 1 ml of ultrapure water from a Milli-Q® water purification system (Millipore Corporation, Billerica, MA, USA) and manually packed into the PVA mold (Fig. 1B). Therefore, to generate structured pores for double-pore scaffolds, 3D printing of PVA filaments was an obvious choice for our manufacturing process presented here. In this work, a 40% filler was used to fabricate PVA molds for double-pore scaffolds, resulting in a filament spacing of 800-850 μm. Leaching of salt as a source of random pores provides the possibility to control the range of pore sizes by choosing the size distribution of salt crystals to mimic the anatomical features of tissues or organs required for their engineering [26]. In this study, NaCl crystals were directly used as supplied by the supplier, with sizes ranging from 300 μm to 600 μm. | The PVA molds could be manufactured with porosities in the range of 20-80% depending on the mold filling, which was shown to correspond to channel distances ranging from 78 μm to 1482 μm [25]. As shown in the SEM image of the structured pore scaffold in Fig. 2Ac, the pores have a square shape with a dimension of ~400 μm × 400 μm and are well interconnected. In the random pore scaffolds, the salt leaching process results in pores with dimensions in the range of 300-600 μm (Fig. 2Bc), as determined by the size distribution of the salt crystals used. The scaffolds had regular, well-structured, and highly interconnected structured pores. Among the structured pores, the scaffolds had a set of randomly porous regions with a square shape of 800 μm × 800 μm. Salt crystals of size 300-600 μm were fused and generated large interconnected pores. The scaffold channels have an elliptical cross-sectional profile, as the round PVA filament is flattened during mold printing, and the distance between two rows of structured pores is approximately 800 μm. The pore dimensions (width 344 μm, height 190 μm) are slightly smaller than those of the printed mold filaments (400 μm × 200 μm), due to shrinkage during PDMS elastomer curing. A region of random pores can be seen in the area between two rows of structured pores (blue dashed line). To demonstrate the possibility of controlling the size of random pores, the above-described PVA mold was filled with smaller salt or sugar crystals, resulting in clearly defined highly interconnected small random pores (20-50 μm) along with the structured pores of 400 μm × 400 μm. The distance between the filaments of a PVA mold needs to be optimized according to the size of the salt or sugar crystals required to generate the random pores. Using different sizes of porous mesh, it is possible to obtain salt or sugar crystals with different size distribution. If large crystals are required, the distance between the deposited PVA filaments must be increased, reducing the porosity of the PVA mold from 40% filling to less. |

It has been previously shown that the compression modulus of porous scaffolds is significantly reduced as their porosity increases. For the same reason, double-pore scaffolds exhibited intermediate mechanical properties compared to structured and random pore scaffolds, indicating the expected relationship between porosity and mechanical stiffness of the scaffolds. The compression modulus of structured pore scaffolds was similar to that of our previous study presented with similar type scaffolds (about 360 kPa).

| GME7 | Tissue engineering | Scaffolding for fabric. | ME16 | Presents a cutting-edge study of three-dimensional printing technologies for tissue engineering applications, with special attention to the development of a computer-aided scaffold design system; direct 3D printing of functionally graded scaffolds; modeling of selective laser sintering (SLS) and fused deposition modeling (FDM) processes; indirect additive manufacturing of scaffolds, with both micro and macro features; the development of a bioreactor; and 3D/4D bio-printing. Technological limitations will be examined to highlight the possibility of future improvements in new three-dimensional printing methodologies for tissue engineering. | Literature review | Architecture design of scaffold. We have adopted a bottom-up approach when constructing a 3D scaffold; that is, first making unit cells, and then assembling them into a 3D scaffold. Using this approach, we can fine-tune the mechanical property, based on the design of the porous structure. We have developed a computer-assisted scaffold design system (CASTS) that can automatically create a highly porous 3D scaffold model with a controlled architecture, and that exactly matches the external surface profile of a native anatomical structure such as bone [10-12]. Natural tissues, such as bone, often have a gradient porous structure, so it is important that the mechanical strength and stiffness between the porous scaffold and the target tissue structure are equal [14]. There are two types of stiffness gradient in bones: radial gradients in long bones, and linear gradients in short and irregular bones. We have achieved the design of radial gradient by arranging the cylindrical unit cells concentrically so that the porosity decreases linearly from the center to the periphery. This linear gradient is produced as a result of varying the strut diameter along the gradient direction. Therefore, we can tailor the stiffness variation for the plaster scaffolds by adjusting the porosity-hardness relationship. The results show that a designed pore size of 250 μm or larger promotes blood vessel growth more than smaller pore sizes [21]. In addition, high porosity does not necessarily lead to increased vascularization, because cell migration and vascularization may be inhibited if there is little interconnectivity between the pores [22]. Recently, researchers have developed a toolbox for evaluating 3D porous scaffolds [23]. This toolbox is based on a modular scaffold design, and allows fine-tuning of scaffold pore size and porosity for vascularization study. *Direct printing. as the success of vertical dimension printing also depends on the adhesion strength between layers. Therefore, when exploring a material for 3D scaffold applications, it is important to consider the available forms of the material in the first stage. Furthermore, to increase the range of 3D printable biomaterials, future development should include the invention of new methods to transform existing biomaterials into suitable forms for 3D printing. In particular, in polyetherketone/hydroxyapatite (PEEK/HA), the results show that HA should be kept at 40% by weight or less to ensure structural integrity. In polyvinyl alcohol/hydroxyapatite (PVA/HA) and polycaprolactone/hydroxyapatite (PCL/HA) systems, HA should be kept at 30% by weight or less to obtain satisfactory scaffold samples with well-defined pore interconnectivity and good structural integrity although the addition of HA initially improved mechanical properties and bioactivity, it compromised material properties during the hydrolytic degradation process [45]. A limitation in the SLS process is the waste of material when building small prototypes such as tissue engineering scaffolds. However, this problem can be overcome by incorporating a compact adaptation system into the SLS partial bed, allowing the adapter to transfer the movement of the SLS partial bed to its own small partial bed [56]. Up to 6.5 times the amount of powder can be saved using this device. A second limitation of scaffolds made with SLS is the low cell retention during cell seeding. One reason is that the materials used for SLS are synthetic and do not favor initial cell attachment. The other reason is that the pores are much larger than the cells due to the issue of SLS resolution, as a result, cells fall through the pores during the seeding process. However, the use of a hybrid 3D scaffold consisting of alternating electrospun nanofibers and 3D printed scaffold layers will prevent cells from falling through them, due to the small pore size of the nanofibers [57, 58]. An alternative solution is to inject cell-loaded collagen hydrogel into the porous structure [59]. There is an unresolved limitation in SLS scaffolds, for example, dust trapping in the inner region of the porous scaffold. It is difficult to manually remove trapped dust, especially for pore sizes below 500 μm. Researchers have explored ultrasonic cleaning with limited success [60]. We obtained such a graph for FDM, based on experimental data from ABS samples [63, 64]. Furthermore, we found feasible porosity and compression stiffness range for our PCL scaffolds designed by the mold system through physical prototype testing [65]. This stiffness range fairly matches the stiffness gradient of cancellous bone in the maxillofacial region, which gradually varies from 35.55 MPa in the molar region to 67.48 MPa in the incisive and canine region [66]. *Indirect printing. unlike direct 3D printing, which produces a scaffold directly from the model material, indirect 3D printing creates a negative mold, usually from a support material, and then casts the desired polymer scaffold out of the mold using a drying method [6, 67, 68]. Collagen scaffolds with internal channel 3D networks can be produced using this approach [69]. Furthermore, freeze-drying was found to be the most suitable drying method in indirect 3D printing, as it induced less shrinkage than critical point drying and accurately reproduced the morphology of the channel design [ Note: The translation has been provided without quotation and double quotation marks at the start and end. | In the second decade after the birth of tissue engineering, 3D printing gradually became a definitive part of this field, due to its control and manufacturing capability. Looking ahead, even once the aforementioned technical challenges are overcome, there will still be a long way to go in transforming academic knowledge into clinical products that benefit society. The current tasks of researchers in this field involve accelerating the standardization and certification of 3D printed medical devices. Prolonged delays in this standardization would further complicate regulatory efforts, especially with three-dimensional bioprinting technologies, which are currently trending and transforming, as the definition of medical device could soon be redefined. Another future trend could emerge in the legal landscape [95], as infringement and protection of intellectual property surrounding 3D printing become more intertwined. Therefore, an early and informed exploration of various legal approaches could be the best preparation for addressing future changes. | Function | Direct/Indirect Printing: Ideally, three-dimensional scaffolds should be highly porous, have well-interconnected pore networks, and have a constant and suitable pore size for cell migration and infiltration [2]. | The researchers proposed the use of 3D printing methods to manufacture customized scaffolds with controlled size and pore structure [4-6]. Fused deposition modeling (FDM), stereolithography, inkjet printing, selective laser sintering (SLS), and color inkjet printing appeared to be the most popular, due to their ability to process plastics. We adopted a bottom-up approach when constructing a 3D scaffold; that is, first making unit cells, and then assembling them into a 3D scaffold. Using this approach, we can fine-tune the mechanical property, based on the design of the porous structure. We have developed a computer-assisted system for tissue scaffolds (CASTS) that can automatically create a highly porous 3D scaffold model with controlled architecture, and that exactly matches the external surface profile of a native anatomical structure such as bone [10-12]. | In this system, nearly 20 polyhedral shapes are selected to form the basic geometry of a unit cell. The scaffold library and parameters of each unit cell, such as pore size and strut size, can be adjusted, and each polyhedral unit can be automatically repeated in a spatial arrangement and dimensioned to form a block that fits the intended application of the scaffold (Figure 1). Next, an anatomically shaped porous scaffold can be created by a Boolean operation between the scaffold block and the actual model of the tissue surface defect. A detailed derivation of the mathematical formulas of the CASTS system for designing and manufacturing tissue engineering scaffolds can be found in Ref. [13]. |

We have developed a computer-assisted scaffold design system (CASTS) that can automatically create a highly porous 3D scaffold model with a controlled architecture, and that exactly matches the external surface profile of a native anatomical structure such as bone [10-12]. Natural tissues, such as bone, often have a gradient porous structure, so it is important that the mechanical strength and stiffness between the porous scaffold and the target tissue structure are equal [14]. There are two types of stiffness gradient in bones: radial gradients in long bones, and linear gradients in short and irregular bones. We have achieved the design of radial gradient by arranging the cylindrical unit cells concentrically so that the porosity decreases linearly from the center to the periphery. This linear gradient is produced as a result of varying the strut diameter along the gradient direction. Therefore, we can tailor the stiffness variation for the plaster scaffolds by adjusting the porosity-hardness relationship. The results show that a designed pore size of 250 μm or larger promotes blood vessel growth more than smaller pore sizes [21]. In addition, high porosity does not necessarily lead to increased vascularization, because cell migration and vascularization may be inhibited if there is little interconnectivity between the pores [22]. Recently, researchers have developed a toolbox for evaluating 3D porous scaffolds [23]. This toolbox is based on a modular scaffold design, and allows fine-tuning of scaffold pore size and porosity for vascularization study. *Direct printing. as the success of vertical dimension printing also depends on the adhesion strength between layers.

Natural tissues, such as bone, typically have a gradient porous structure, so it is important that the mechanical strength and stiffness between the porous scaffold and the target tissue structure are equal [14]. There are two types of stiffness gradients in bones: radial gradients in long bones, and linear gradients in short and irregular bones. | Direct printing: we adopted a bottom-up approach when constructing a 3D scaffold; that is, first making unit cells, and then assembling them into a 3D scaffold. We have achieved the design of the radial gradient. Another method for designing gradient structures is based on the shape function and refinement of the hexagonal mesh [18]. A new method based on the sigmoid function and the radial basis function has recently been developed to determine the growth rate of structures with functional grading, and the resulting models can be exported as STL files and 3D printed [19]. The results show that a designed pore size of 250 μm or larger promotes the growth of blood vessels more than smaller pore sizes [21]. | Direct printing: In this system, nearly 20 polyhedral forms are selected to form the basic geometry of a unit cell.

Therefore, we can tailor the stiffness variation for gypsum scaffolds by adjusting the porosity-hardness relationship. Hexagonal shape and refinement function: In this method, a truncated bone is subdivided and represented using various irregular hexahedral elements, which are then converted into various irregular pore elements based on the shape function. The complete pore model is obtained after a union operation between the irregular pores, and then the resulting bone fold is obtained by performing a difference operation between the contour model and the pore model. With this method, a well-defined pore size distribution can be achieved for gradient bone scaffold design. In addition, high porosity does not necessarily lead to increased vascularization, as cell migration and vascularization may be inhibited if there is little interconnectivity between the pores [22]. |

We have adopted a bottom-up approach when constructing a 3D scaffold; that is, first making unit cells, and then assembling them into a 3D scaffold. Using this approach, we can fine-tune the mechanical property, based on the design of the porous structure. We have developed a computer-assisted scaffold design system (CASTS) that can automatically create a highly porous 3D scaffold model with a controlled architecture, and that exactly matches the external surface profile of a native anatomical structure such as bone [10-12]. Natural tissues, such as bone, often have a gradient porous structure, so it is important that the mechanical strength and stiffness between the porous scaffold and the target tissue structure are equal [14]. There are two types of stiffness gradient in bones: radial gradients in long bones, and linear gradients in short and irregular bones. We have achieved the design of radial gradient by arranging the cylindrical unit cells concentrically so that the porosity decreases linearly from the center to the periphery. This linear gradient is produced as a result of varying the strut diameter along the gradient direction. Therefore, we can tailor the stiffness variation for the plaster scaffolds by adjusting the porosity-hardness relationship. The results show that a designed pore size of 250 μm or larger promotes blood vessel growth more than smaller pore sizes [21]. In addition, high porosity does not necessarily lead to increased vascularization, because cell migration and vascularization may be inhibited if there is little interconnectivity between the pores [22]. Recently, researchers have developed a toolbox for evaluating 3D porous scaffolds [23]. This toolbox is based on a modular scaffold design, and allows fine-tuning of scaffold pore size and porosity for vascularization study. *Direct printing. as the success of vertical dimension printing also depends on the adhesion strength between layers. Therefore, when exploring a material for 3D scaffold applications, it is important to consider the available forms of the material in the first stage. Furthermore, to increase the range of 3D printable biomaterials, future development should include the invention of new methods to transform existing biomaterials into suitable forms for 3D printing. In particular, in polyetherketone/hydroxyapatite (PEEK/HA), the results show that HA should be kept at 40% by weight or less to ensure structural integrity. In polyvinyl alcohol/hydroxyapatite (PVA/HA) and polycaprolactone/hydroxyapatite (PCL/HA) systems, HA should be kept at 30% by weight or less to obtain satisfactory scaffold samples with well-defined pore interconnectivity and good structural integrity although the addition of HA initially improved mechanical properties and bioactivity, it compromised material properties during the hydrolytic degradation process [45]. A limitation in the SLS process is the waste of material when building small prototypes such as tissue engineering scaffolds. However, this problem can be overcome by incorporating a compact adaptation system into the SLS partial bed, allowing the adapter to transfer the movement of the SLS partial bed to its own small partial bed [56]. Up to 6.5 times the amount of powder can be saved using this device. A second limitation of scaffolds made with SLS is the low cell retention during cell seeding. One reason is that the materials used for SLS are synthetic and do not favor initial cell attachment. The other reason is that the pores are much larger than the cells due to the issue of SLS resolution, as a result, cells fall through the pores during the seeding process. However, the use of a hybrid 3D scaffold consisting of alternating electrospun nanofibers and 3D printed scaffold layers will prevent cells from falling through them, due to the small pore size of the nanofibers [57, 58]. An alternative solution is to inject cell-loaded collagen hydrogel into the porous structure [59]. There is an unresolved limitation in SLS scaffolds, for example, dust trapping in the inner region of the porous scaffold. It is difficult to manually remove trapped dust, especially for pore sizes below 500 μm. Researchers have explored ultrasonic cleaning with limited success [60]. We obtained such a graph for FDM, based on experimental data from ABS samples [63, 64]. Furthermore, we found feasible porosity and compression stiffness range for our PCL scaffolds designed by the mold system through physical prototype testing [65]. This stiffness range fairly matches the stiffness gradient of cancellous bone in the maxillofacial region, which gradually varies from 35.55 MPa in the molar region to 67.48 MPa in the incisive and canine region [66]. *Indirect printing. unlike direct 3D printing, which produces a scaffold directly from the model material, indirect 3D printing creates a negative mold, usually from a support material, and then casts the desired polymer scaffold out of the mold using a drying method [6, 67, 68]. Collagen scaffolds with internal channel 3D networks can be produced using this approach [69]. Furthermore, freeze-drying was found to be the most suitable drying method in indirect 3D printing, as it induced less shrinkage than critical point drying and accurately reproduced the morphology of the channel design [ Note: The translation has been provided without quotation and double quotation marks at the start and end. | In the second decade after the birth of tissue engineering, 3D printing gradually became a definitive part of this field, due to its control and manufacturing capability. Looking ahead, even once the aforementioned technical challenges are overcome, there will still be a long way to go in transforming academic knowledge into clinical products that benefit society. The current tasks of researchers in this field involve accelerating the standardization and certification of 3D printed medical devices. Prolonged delays in this standardization would further complicate regulatory efforts, especially with three-dimensional bioprinting technologies, which are currently trending and transforming, as the definition of medical device could soon be redefined. Another future trend could emerge in the legal landscape [95], as infringement and protection of intellectual property surrounding 3D printing become more intertwined. Therefore, an early and informed exploration of various legal approaches could be the best preparation for addressing future changes. | Manufacturing and Assembly | Direct/indirect printing: The results show that a designed pore size of 250 μm or larger promotes the growth of blood vessels more than smaller pore sizes. | FDM/SLS/ translated into ingles is FDM/SLS/. | - |

| GME8 | Medicines | Controlled/ sustained release medications | ME5 | This study tests the hypothesis of whether 3DP (FDM) can be used to create a zero-order drug release dosage form for carbamazepine. The aim of this study is to design and investigate 3D printed scaffolds with different pore parameters to determine the optimal parameters that can release carbamazepine in a zero-order manner. | The Rhodamine B (drug substitute) and sodium dodecyl sulfate (SDS, 99%; used as a dissolution medium) were obtained from Alfa Aesar (Massachusetts, MA). The phosphate-buffered saline (PBS, 10, Ultra Pure Grade; used as a dissolution medium) was obtained from Vivantis (Selangor Darul Ehsan, Malaysia). The analytical grade carbamazepine was obtained from Sigma-Aldrich (St. Louis, MO). The Tegretol 200 tablets (carbamazepine) were obtained from Novartis (Basel, Switzerland). The scaffolds were designed to have a cup-shaped body, with a cover that would seal it after packing the drug inside (Fig. 1). The three-dimensional model of the scaffolds was created using AutoCad 2015 (Autodesk, San Francisco, CA). Edges were constructed on the scaffolds to secure the cover to the body of the scaffold. The purpose of this design was to allow the scaffold to be sealed after packing the Rhodamine B into the body of the scaffold, so that the only way to release the drug into the environment was through the holes, thus ensuring a constant surface for interaction. The 3D models were printed using a Da Vinci 1.0 3D printer and XYZware software (XYZprinting, CA). The printing filament used by the 3D printer was a 1.75 mm diameter acrylonitrile butadiene styrene (ABS) filament. The printing settings used were the highest density (90%), the finest layer height (0.1 mm) for the highest resolution, and the standard printing speed defined by the software. Two scaffold designs were 3D printed with ABS, one with the holes positioned on the side and another with the holes positioned on the top/bottom. Both designs had a diameter of 17 mm, a wall thickness of 1 mm, and a base thickness of 1.5 mm. To account for the 3D printer's resolution, the scaffold cover was designed with a diameter of 14 mm to fit snugly into the body of the scaffold. The thickness of the cover was 1.5 mm. A thin layer of paraffin film was used to cover the small gaps between the cover and the body of the scaffold to ensure that drug release into the medium only occurred through the designed holes. All lengths were measured from the 3D model of the scaffolds. 3D models of the scaffolds were constructed with different positions (side vs. top and bottom), hole diameters (1.5 and 2 mm), and number of holes (4, 5, 8, 12). Dissolution tests and high-performance liquid chromatography analysis were performed. | The scaffolds with holes on the side exhibited a zero-order dissolution kinetics representative of a sustained-release tablet. The results showed that scaffolds with 12 holes and 1 mm diameter produced the most linear profiles. The scaffold design was able to release drugs reproducibly at a constant rate after 5 minutes. It was observed that all scaffolds had drug and excipient residues after 8 hours of testing, so we extrapolated that the disintegration and dissolution process lasted at least 8 hours. Overall, increasing the hole diameters increased the release rate of carbamazepine from the scaffolds while maintaining the linearity of the drug release profile. There was no clear association between the number of scaffold holes and the release rate of carbamazepine, except in the group of scaffolds with a hole diameter of 2 mm. Using rhodamine B as a drug substitute, our study demonstrated that placing the holes on the side resulted in more linear release profiles than holes on the top and bottom of the 3D-printed scaffolds. Of the 3 scaffold configurations (holes on the top, holes on the side, and holes on both the top and bottom), scaffolds with side holes produced a considerably better linear release profile than the other 2 configurations, with an R2 of 0.917 compared to 0.776 and 0.808. Other changes in the scaffolds with side holes, in terms of the number and diameter of the holes, also demonstrated good linearity, except in the scaffold with 8 holes of 1.5 mm diameter and the scaffold with 12 holes of 2 mm diameter. In all scaffolds using carbamazepine, good linear release profiles of carbamazepine were observed, with an R2 value of at least 0.91. Overall, increasing the hole diameters increased the release rate of carbamazepine from the scaffolds while maintaining the linearity of the drug release profile. | This study has shown that 3DP is a useful technique for designing scaffolds that have linear release profiles after 5 minutes, with carbamazepine as our drug of choice. This study has also demonstrated that the diameters of the holes in the printed scaffolds have a positive relationship with the release rate of carbamazepine, but not with the number of holes. The scaffold design described in this study forms a basis that can be further optimized for zero-order release dosage form, to reduce CNS dose-dependent side effects of carbamazepine. The ultimate goal of this research is to benefit epilepsy patients by achieving the therapeutic doses necessary for seizure control through minimizing DEA side effects, and improving patient compliance through a dosage that provides a zero-order drug release profile. | Function | Drug container for sustained release, zero release formulations, at a specific rate for treatment. | 3D printing has the potential to manufacture zero-release formulations with complex geometries. 3D printed scaffolds were designed with different hole positions (side and top/bottom), hole numbers (4, 8, and 12), and hole diameters (1, 1.5, and 2 mm). Dissolution tests and high-performance liquid chromatography analysis were performed. | The fluctuations in drug serum concentrations are reduced, thus reducing the side effects. The usual dose of carbamazepine for epilepsy in adults is 800-1600 mg/day, which corresponds to a release rate of 0.56-1.11 mg/min. The maximum rate obtained in this study was 0.0126 mg/min, which would not be sufficient to reach the therapeutic dose. However, this study has shown that an increase in the diameter of the scaffold holes can lead to an increase in the drug release rate. Therefore, future studies can explore the optimal size of the holes that will produce the desired drug dissolution rate. The low drug release rate can also be avoided by increasing the amount of carbamazepine in the scaffold. |

Recent studies have shown that ABS scaffolds are biocompatible for cartilage regeneration and nucleus pulposus tissue regeneration, as well as ear-shaped scaffolds for skin cell culture. Although ABS is not bioresorbable, it can potentially be used in pharmaceutical applications due to its biocompatibility and strong chemical resistance, allowing it to safely exit the body like most foreign bodies. However, further studies are needed to address current concerns about the possible leaching of acrylonitrile monomers, which can be carcinogenic. In addition to ABS, various polymers have also been used in the pharmaceutical industry for 3D printing of drug delivery systems using the FDM technique. An example is the use of polylactic acid as a drug eluting implant for slow and partial release of nitrofurantoin and hydroxyapatite antibiotics. Polyvinyl alcohol has also been used as a drug carrier for investigating the effects of geometry on drug release from 3D printed tablets. In fact, poly(vinyl alcohol) has been used as a drug carrier for modified release tablets of aminosalicylate, extended release tablets of prednisolone, and modified release tablets of budesonide. Furthermore, ethylene vinyl acetate has been used as a novel drug carrier for a 3D printed T-shaped intrauterine drug delivery system for indomethacin. In a similar study, polycaprolactone has also been used to deliver indomethacin in a controlled manner in a 3D printed prototype of an intrauterine T-shaped implantable system based on polycaprolactone. Considering the wide variety of polymers that can potentially be used for drug delivery systems, we encourage future studies to also explore these polymers for drug scaffold designs, such as carbamazepine. |
| GME8 | Medicines | Controlled/ sustained release medications | ME5 | This study tests the hypothesis of whether 3DP (FDM) can be used to create a zero-order drug release dosage form for carbamazepine. The aim of this study is to design and investigate 3D printed scaffolds with different pore parameters to determine the optimal parameters that can release carbamazepine in a zero-order manner. | The Rhodamine B (drug substitute) and sodium dodecyl sulfate (SDS, 99%; used as a dissolution medium) were obtained from Alfa Aesar (Massachusetts, MA). The phosphate-buffered saline (PBS, 10, Ultra Pure Grade; used as a dissolution medium) was obtained from Vivantis (Selangor Darul Ehsan, Malaysia). The analytical grade carbamazepine was obtained from Sigma-Aldrich (St. Louis, MO). The Tegretol 200 tablets (carbamazepine) were obtained from Novartis (Basel, Switzerland). The scaffolds were designed to have a cup-shaped body, with a cover that would seal it after packing the drug inside (Fig. 1). The three-dimensional model of the scaffolds was created using AutoCad 2015 (Autodesk, San Francisco, CA). Edges were constructed on the scaffolds to secure the cover to the body of the scaffold. The purpose of this design was to allow the scaffold to be sealed after packing the Rhodamine B into the body of the scaffold, so that the only way to release the drug into the environment was through the holes, thus ensuring a constant surface for interaction. The 3D models were printed using a Da Vinci 1.0 3D printer and XYZware software (XYZprinting, CA). The printing filament used by the 3D printer was a 1.75 mm diameter acrylonitrile butadiene styrene (ABS) filament. The printing settings used were the highest density (90%), the finest layer height (0.1 mm) for the highest resolution, and the standard printing speed defined by the software. Two scaffold designs were 3D printed with ABS, one with the holes positioned on the side and another with the holes positioned on the top/bottom. Both designs had a diameter of 17 mm, a wall thickness of 1 mm, and a base thickness of 1.5 mm. To account for the 3D printer's resolution, the scaffold cover was designed with a diameter of 14 mm to fit snugly into the body of the scaffold. The thickness of the cover was 1.5 mm. A thin layer of paraffin film was used to cover the small gaps between the cover and the body of the scaffold to ensure that drug release into the medium only occurred through the designed holes. All lengths were measured from the 3D model of the scaffolds. 3D models of the scaffolds were constructed with different positions (side vs. top and bottom), hole diameters (1.5 and 2 mm), and number of holes (4, 5, 8, 12). Dissolution tests and high-performance liquid chromatography analysis were performed. | The scaffolds with holes on the side exhibited a zero-order dissolution kinetics representative of a sustained-release tablet. The results showed that scaffolds with 12 holes and 1 mm diameter produced the most linear profiles. The scaffold design was able to release drugs reproducibly at a constant rate after 5 minutes. It was observed that all scaffolds had drug and excipient residues after 8 hours of testing, so we extrapolated that the disintegration and dissolution process lasted at least 8 hours. Overall, increasing the hole diameters increased the release rate of carbamazepine from the scaffolds while maintaining the linearity of the drug release profile. There was no clear association between the number of scaffold holes and the release rate of carbamazepine, except in the group of scaffolds with a hole diameter of 2 mm. Using rhodamine B as a drug substitute, our study demonstrated that placing the holes on the side resulted in more linear release profiles than holes on the top and bottom of the 3D-printed scaffolds. Of the 3 scaffold configurations (holes on the top, holes on the side, and holes on both the top and bottom), scaffolds with side holes produced a considerably better linear release profile than the other 2 configurations, with an R2 of 0.917 compared to 0.776 and 0.808. Other changes in the scaffolds with side holes, in terms of the number and diameter of the holes, also demonstrated good linearity, except in the scaffold with 8 holes of 1.5 mm diameter and the scaffold with 12 holes of 2 mm diameter. In all scaffolds using carbamazepine, good linear release profiles of carbamazepine were observed, with an R2 value of at least 0.91. Overall, increasing the hole diameters increased the release rate of carbamazepine from the scaffolds while maintaining the linearity of the drug release profile. | This study has shown that 3DP is a useful technique for designing scaffolds that have linear release profiles after 5 minutes, with carbamazepine as our drug of choice. This study has also demonstrated that the diameters of the holes in the printed scaffolds have a positive relationship with the release rate of carbamazepine, but not with the number of holes. The scaffold design described in this study forms a basis that can be further optimized for zero-order release dosage form, to reduce CNS dose-dependent side effects of carbamazepine. The ultimate goal of this research is to benefit epilepsy patients by achieving the therapeutic doses necessary for seizure control through minimizing DEA side effects, and improving patient compliance through a dosage that provides a zero-order drug release profile. | Manufacturing and Assembly | The technique used should be cost-effective and widely available. | FDM | FDM is often the cheapest of all 3DP techniques and therefore more affordable for the general public. In addition, the materials used are usually inert polymers that offer great mechanical strength. For 3DP to achieve large-scale therapy customization, the technique used would have to be cost-effective and widely available. FDM seems to be a suitable option for this purpose. Therefore, this study tests the hypothesis of whether 3DP (FDM) can be used to make a zero-order drug release dosage form for carbamazepine. |
