Costing, health and environmental
Here are the summarized general rules (RG) of design, categorized by common topics. The competitive and innovative advantages are highlighted in bold, and their application is illustrated with Figures or Tables.
Process chain costing model.
The guidelines require a specific evaluation of costs to make decisions. The following describes the guideline for quantifying FFF process chain costs.
RG-CP-14. The costs should include per service and service time, whether 3D printing, or any other conventional process combined. It should also include the cost of the material, whether printed or any other.
The service costs include machinery depreciation, energy consumption, depreciation of computers and software licenses with their energy consumption and internet service, and skilled labor.
Assessment of health and environmental impacts.
Health and environmental impacts associated with extra materials and processes should also be quantified. A guideline for this purpose is presented below.
RG-CP-15. It is recommended that health and environmental impacts be evaluated using a matrix of weighted criteria, and qualified according to the material safety data sheets, using the GHS (Globally Harmonized System, see Figure 2) scale or the NFPA (National Fire Protection Association, see Figure 3) scale, preferring GHS values for being more specific in terms of risks and hazards.
