In fused deposition modeling, the model is produced by extruding filament of material which harden immediately to form layers. A thermoplastic filament that is wound on a coil is unreeled to supply material to an extrusion nozzle head. The nozzle head heats the material and enables a construct layer-by-layer. Typically stepper motors are employed to move the extrusion head and adjust the flow. The head can be moved in both horizontal and vertical directions, and control of the mechanism is typically done by a computer-aided manufacturing (CAM) software, here Repetier Host.
