Method for manufacturing a part of electroconductive material by additive manufacturing

A method for manufacturing at least one part of electroconductive material by additive manufacturing on a powder bed, including a step of:

• a) by means of a first additive manufacturing machine, manufacturing said at least one part on a support plate, layer by layer, said part being bounded by a portion of an outer contour surface which is facing and spaced from said support plate, and which is connected to said support plate by at least one support material bridge of the part,
• further comprising the steps of:
• b) by means of said first additive manufacturing machine, manufacturing a reference element on the support plate in a predetermined position spaced apart from said part, so that said at least one part is located in the space with respect to said reference element,
• c) mounting said support plate on a second machine for cutting said at least one part, and positioning said support plate on said machine based on the position of said reference element,
• d) using a wire from said second machine to cut by electrical discharge machining said at least one part by passing the wire between said at least one part and said support plate along said portion of the outer contour surface.
