Fused deposition modeling, also known as fused filament fabrication, creates 3D printed plastic parts by extruding thermoplastic filaments in sequential, back-to-back layers. This 3D printing process delivers high accuracy, durability and consistency, so parts are unparalleled in mechanical, thermal and chemical strength. It is a streamlined and cost effective process that is ideal for running designs, fit and function testing, short production runs, jigs, and fixtures.
