This page serves as a framework, database, knowledge base, and design and manufacturing methodology for those designing, manufacturing, or using Fused Filament Fabrication (FFF) or Fused Deposition Modeling (FDM) technology. You will find basic knowledge about the process, parameters, design rules and models on the DF-FFF page. Likewise, Medical & personalization page assist in the design of medical and customized products. The Process Chain page contain information about combines FFF with other conventional manufacturing processes to enhance the FFF process. Lastly, Failure Theory page helps predict and improve the mechanical properties and strength of parts manufactured with FFF.
