Beschreibung
Zusammenfassung:	The extruder system includes a supply configured to receive raw material and comprising a heater configured to melt the raw material into extrudable material, an extruder configured to receive the extrudable material from the supply and comprising a screw conveyor configured to convey the extrudable material towards an extrusion nozzle of the extruder and cause an overpressure inside the extruder to allow selective extrusion via the extrusion nozzle. The extruder further includes a plunger arranged at or near the extrusion nozzle and configured to selectively release at least a part of the overpressure and thereby control a flow of extrudable material out of the extrusion nozzle to reduce oozing of extrudable material after stopping the flow.
