Abstract: The invention relates to an extrusion nozzle comprising at least one core (21-25). Said extrusion nozzle is also provided with a plurality of flow channels (11-19) for melt streams, said channels merging inside the extrusion nozzle to form the desired profiled element. The inventive extrusion nozzle consists of a plurality of plates (1-7). The flow channels (11-19) are separated from each other for all plates comprising at least one core (3-7), with the exception of the last plate (7), such that the at least one core (21-25) is connected to the remaining plate by the connecting elements (34-38) between the flow channels (11-20). When the flow channels (11-19) in the last plate (7) are continuously interconnected, the at least one core (21-25) of the last plate (7) is screwed onto the corresponding core or cores of the adjacent plate (6). When the flow channels (11-19) in the last plate (7) are interconnected only over part of the height thereof, the at least one core (21-25) of the last plate (7) is connected to the remaining plate (7) by means of the remaining connecting elements.

Abstract: A single screw micro-extruder for a 3D printer includes a feed chamber with an opening for receiving solid plastic pellets. An extrusion barrel extends from the feed chamber and has an inner conically shaped bore between input and output ends. The bore has a mouth at the input end and an exit opening at the output end with a melt section therebetween. A rotatable screw is attached to a torque drive of the printer, and extends through the feed chamber and conical bore of the barrel. A constant or tapered diameter of the screw root core, from the input end toward the output end of the barrel, forms a decreasing channel root depth in a helical path for compression between a root core surface and an inner surface of the bore for pressurizing melt in the melt section of the barrel to exit an extrusion nozzle.
