Abstract
3D Fused Filament Fabrication (FFF) is improved by heating the deposition nozzle with one or more non-contact heat sources. 3D FFF is also improved by cooling the deposition nozzle with one or more active cooling elements. Temperature control of the deposition nozzle is improved due to the reduction in mass of the nozzle by eliminating conductive heat elements and their associated devices, such as thermal transfer blocks. Responsiveness of the nozzle is improved by using lasers as non-contact heating sources, allow for rapid changes in temperature when necessary.
