Zusammenfassung:	An additive manufacturing assembly 10 is disclosed, for an additive manufacturing extruder 1 comprising a filament passageway defined by a heat sink 5 (Figure 8), a heated nozzle tip 14, and a filament tube 16 separating the nozzle and the heat sink. The extruder may further comprise ventilation means such as a fan or an air knife/jet 24 mounted on the sides and a flow passageway 25 limiting heat convection between the heat sink and nozzle. A resilient spring 13 may also keep the sink and nozzle apart. The filament may be driven through the extruder by a pair of opposed drive wheels, motor, and gear assembly (Figure 14). The assembly may be incorporated in a housing 2 (Figure 2) and mounted using a mounting pin MP (Figure 1).
