Method and System to Introduce In-Process Local Thermal Modifications to Fused Filament Fabrication 3D Printing for Approved Surface Finish and Dimensional Tolerance

Background Additive manufacturing, also known as 3D printing, is a fabrication process to build 3D objects layer by layer based on computer aided design (CAD) models, or digital 3D models. Current filament or wire feedstock-based technologies, including the fused filament fabrication (FFF), are desirable for printing thermal plastic materials due to...
