A method for additive manufacturing of metal components

A method for additive manufacturing three-dimensional metallic components (12), wherein the components (12) layer or partially under vacuum conditions by fusing a metallic material with the component (12) to a processing station by means of a radiation source having a high energy density can be constructed. In order to keep by the radiation itself to the processing site registered energy is relatively low, wherein the wire is pre-heated under vacuum conditions before reaching the processing station that the metallic material is supplied as a wire (28) is proposed.
