Abstract
The invention relates to a method for the additive manufacture of three-dimensional metallic components (12), said components (12) being built layer-by-layer or section-by-section under vacuum conditions by fusing a metallic material with the component (12) at a machining point by means of a radiation source with a high energy density. In order to keep the energy applied to the machining point by the radiation itself relatively low, the metallic material is supplied in the form of a wire (28) which is preheated under vacuum conditions before reaching the machining point.
Claims11
A method for additive manufacture of a three-dimensional metallic component, the method comprising:
- preheating a wire comprising metallic material under vacuum conditions by at least one of (1) direct electric preheating by means of resistance heating and (2 inductive preheating;
- delivering the preheated wire to a processing location;
- fusing the metallic material at the processing location under vacuum conditions by means of a radiation source with high energy density, said radiation source comprised of a laser beam;
- and
- continuously repeating the delivering and fusing steps while maintaining the wire in a preheated state, thereby building up said component in layers or sections.
