Abstract

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.
