Abstract
Fused deposition modeling (FDM) systems and methods may be improved via laser pre-heating of the target substrate ahead of the extrusion nozzle. Higher interface temperatures lead to improved wetting, diffusion, and randomization, thus improving the bond between filaments and between layers, and reducing anisotropy in the resulting finished part.
