Aspects of devices in which plastic is extruded for a three dimensional printer. Novel designs for components of a high performance fused filament extrusion head are disclosed within, a novel “heat-break” and wear resistant “feed tube”. The feed tube serves as a path for filament as it is fed from the cold end into the hot end. The heat-break rigidly connects the cold end to the hot end while providing resistance to the flow of heat.
