More Information
Summary:Disclosed are methods and systems for additive manufacturing in a fused filament fabrication process with the application of thermal radiation whereby the thermal radiation is irradiated at an emission spectrum approximately the same as the absorbance spectrum of the modeling material. Three-dimensional objects are formed by depositing modeling material from a print head 104 onto a base 102 while thermal radiation is simultaneously applied through a print heating device 110 and a layer heating device 310 whereby the movements and devices are controlled by control signals from a controller 116. In one embodiment, the print head 104 is cooled by pressured gas and is disposed inside of the print environment while the linear motion guides 112 are disposed external to the print environment.
