FDM (Fused Deposition Modeling) 3D Printers melts plastic and extrudes it in a pattern, building up a 3D shape layer by layer. The pattern is determined by a digital 3D model, which the software “slices” into layers. The printers can print in a variety of materials: most frequently PLA, a softer but somewhat brittle corn- or sugar-based plastic, or ABS, which is a stronger and more pliable plastic used in high-force applications. These prints finish quickly and with minimal post processing, which makes them fantastic for everyday printing and rapid prototyping applications.
