Beschreibung
Zusammenfassung:	A nozzle assembly for a printer head of a 3D printer includes a guide held in a fixed position relative to the printer head and extending from a first end to a second end along a longitudinal axis. A drive mechanism extends from a feed end to a discharge end along the longitudinal axis. The feed end defines a feed opening for receiving a filament from a feed system, and the discharge end defines a discharge opening for discharging the filament from the nozzle assembly. The drive mechanism is movable relative to the guide, and the drive mechanism includes a drive surface for engaging the filament and causing the filament to move from the feed opening to the discharge opening, in response to the drive mechanism moving relative to the printer head. The nozzle assembly further includes a motor for moving the drive mechanism relative to the printer head.
