|Title:||ENHANCED LAYER ADHESION ADDITIVE IN MANUFACTURING BY USE OF MULTIPLE HEATING STEPS|
Provided are systems and methods for additive manufacturing, which systems and methods yield parts having improved interlay er adhesion. In the disclosed technology, additional heating steps are applied on the upper surface of the already printed workpiece so as to offset the dropping temperature of that surface during part fabrication. These heating steps elevate the temperature of the surface to a value that results in a molten interface with subsequently-applied build material, leading to improved interlayer adhesion. This technology is applicable to a variety of additive manufacturing processes, including but not limited to selective laser sintering, fused filament fabrication, and large format additive manufacturing approaches.
