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...

A Laser-Based Local Preheating Process to Enhance the as Built Strength Isotropy of the Fused Filament Fabrication (FFF) Part

Fused filament fabrication (FFF) is a 3D printing process that adds material layer-by-layer to form a 3D object. Today, 3D printing can produce a range of objects from simple children’s toys to fully-functioning human hearts. However, the products created by FFF still contain a significant amount of error in terms of structural variability during...
