Additive manufacturing, or 3D printing, has been a popular method of creating prototypes since the 1980s and is quickly becoming the fastest, most affordable way to create custom consumer goods as well. But how does this trendy technology work? There are several different methods of 3D printing, but the most widely used is a process known as Fused Deposition Modeling (FDM). FDM uses the extrusion process to build 3D models. FDM printers use a thermoplastic filament, which is heated to its melting point and then extruded, layer by layer, to create a three dimensional object.
