Fused deposition modeling (FDM), also known as fused filament fabrication (FFF) or Material Extrusion (MEX), 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, producing parts with exceptional mechanical, thermal, and chemical strength. It is a streamlined and cost-effective process, ideal for running designs, fit and function testing, short production runs, jigs, and fixtures.
