摘要： A method and an apparatus for extrusion of fiber-reinforced plastic material for the additive manufacture of a component is disclosed. The fiber-reinforced plastic material is supplied to the extrusion apparatus and heated in a heating zone of the extrusion apparatus in order to then supply the fiber-reinforced plastic material to an extrusion nozzle of the extrusion apparatus, at which a material thread comprising fiber-reinforced plastic material is extruded for the component to be manufactured. In order to convey the fiber-reinforced plastic material through the heating zone, a screw conveyor of the extrusion apparatus is utilized, which has a length-diameter ratio of less than a set value. In the heating zone a maximum volume is provided for the fiber-reinforced plastic material and a rotational speed of the screw conveyor is limited to a maximum of speed.

摘要： A charging system for feeding processing material to at least one extruder screw including a hopper configured to conduct the processing material along a feed direction to the extruder screw, and a material reservoir for the gravity-driven feeding of the processing material to the hopper. The charging system also includes a feeding device via which processing material recirculated at the hopper against the feed direction by action of the extruder screw can again be conveyed in the direction of the extruder screw together with processing material fed from the material reservoir.
