    Abstract: The invention relates to an additive method for producing metal parts having an amorphous, crystalline and/or semi-crystalline structure for medical technology, rapid prototyping and rapid manufacturing, rapid tooling as well as all domains, in which RP-technologies are used, rapid manufacturing of lightweight components for the aerospace industry (closed honeycomb structures, etc) and the direct production of special parts and replacement parts (Selective Amorphous Metal Extrusion (SAME)). An amorphous, metallic starting material is heated in an extruder (9) by means of an extrusion method to above the glass transition range for generating a thermoplastic behavior, is extruded, is then selectively applied in two dimensions onto a construction platform (10) in the form of an extruded metal thread, and is subsequently cooled, wherein the two-dimensional application and the cooling of the extruded material thread is continued until the metal part is completed. The installation for carrying out the method consists of a three-dimensionally displaceable kinematic system (8), a construction platform (10) and an extruder (9) arranged on the three-dimensionally displaceable kinematic system (8). The extruder (9) comprises an extruder screw (1) for the amorphous, metallic starting material that is to-be extruded, a heated or partially heated housing (2) and an exchangeable nozzle (3) arranged on the housing (2). According to the invention, an active cooling (4) is directed below the nozzle (3) onto the extruded material exiting the nozzle (3).
