The material in this process is a polymer filament that is supplied by a roll. A print head liquefies the material in a manner similar to a hot-melt glue gun. As a result, components are created layer by layer out of liquid polymer. A second print head adds support material, which it deposits into cavities and at overhangs, for example, because the component has to be supported in these areas during the printing process. This support material is removed after the component is finished.
FUSED FILAMENT FABRICATION
Evonik collaborates with leading technology providers to develop new ready-to-use filament materials suitable for the FFF technology.
