Method and device for additive manufacturing of parts out of amorphous or partially crystalline metals by extrusion

Invention is used for additive manufactur-ing of parts out of amorphous or partly crystalline metals with low melting point. This is done with an extrusion method. The used material, metal granulate, is heated up to the glass transition temperature and partly up to the melting temperature. By doing so, the material is moved into a thermoplastic state. After heating, the material can then be extruded by pressure and is selectively placed onto a building platform. The system described in this invention is able to manufacture hollow constructions along with complex parts, all with good mechanical properties. Due to the generating of the part onto the building platform it is not necessary to clean or post process the part as it would be with other methods.
