The charging system has a feed system (8), using which processing material that is returned to the hopper (5) in the opposite direction to the feed direction (Z) as a result of the action of the extruder screw (2), can be conveyed again, together with processing material fed from the material reservoir (3), towards the extruder screw (2).
Method and device for the extrusion of thermomechanically deformable materials, as well as a compact screw extruder. The configuration of the material infeed in a screw extruder, has a significantly smaller length-diameter ratio than known solutions from the fields of injection moulding and additive manufacturing and a crushing tool, located in the funnel-shaped infeed region of the vertically arranged screw extruder which prevents the rotational movement of the material in the funnel, and also thereby forces movement in the conveying direction of the screw extruder in combination with the gradient of the screw flanks. In addition, a portion of the coarse material is crushed, whereby the bulk material density is increased in the region of the screw and less air must be pressed out of the material in the region of the plasticization and homogenization zone.

DEVICE AND METHOD FOR THE EXTRUSION OF THERMO-MECHANICALLY DEFORMABLE MATERIALS IN BULK FORM, AND COMPACT SCREW EXTRUDER
The invention relates to a method and a device for the extrusion of thermo-mechanically deformable materials, as well as a compact screw extruder. The novelty value of the described invention lies in the configuration of the material infeed in a screw extruder, which has a significantly smaller length-diameter ratio than known solutions from the fields of injection moulding and additive manufacturing. The object of the invention is achieved by a crushing tool, which is located in the funnel-shaped infeed region of the vertically arranged screw extruder. The crushing tool prevents the rotational movement of the material in the funnel, and also thereby forces a movement in the conveying direction of the screw extruder in combination with the gradient of the screw flanks. In addition, a portion of the coarse material is crushed, whereby the bulk material density is increased in the region of the screw and less air must be pressed out of the material in the region of the plasticisation and homogenisation zone.
The invention relates to an extruder (7) for a system for the additive manufacture of freely formable metal parts from a composite material with or without a support structure using an extrusion method, said extruder being arranged on a three-dimensionally movable kinematic system (18) with a construction platform (11). The extruder (7) consists of a housing (2) and a worm (4) arranged in the housing (2), and the extruder (7) is provided with a mechanical drive (1) for the composite material to be extruded and a replaceable nozzle (3) which is arranged on the housing (2). The housing (2) is connected to the mechanical drive (1) via suitable means in order to transport the composite material. The housing (2) is divided into • a feed section (5) with an active cooling (9), wherein the housing (2) is designed as a funnel (22), and the material of the housing (2) consists of a material with good thermal conductivity, said worm (4) having a smaller shaft diameter, • a separation zone (6), in which the housing (2) consists of a material with poor thermal conductivity and thermally separates the cooled feed zone (5) from a heated plasticizing and homogenization zone (8), • the plasticizing and homogenization zone (8), in which the housing (2) consists of a material with good thermal conductivity and is provided with an active heating (10), said worm (4) having a larger shaft diameter in the plasticizing and homogenization zone than in the upper zones (5, 6), and • a discharge zone (12), which consists of a replaceable nozzle (3) made of an abrasion-resistant material.
