FIELD: machine building.
SUBSTANCE: invention relates to an apparatus and method of making part by selective melting of powder. Installation comprises a means producing a beam, for example a laser beam or an electron beam, and a means moving a point of impact of beam over a layer of powder. Collecting element splashes molten powder (24) formed during local melting of powder with beam (11), comprises hole (15) for passage of beam (11).
EFFECT: installation incorporates means of moving said collecting element (14) together with beam (11) over layer of powder.
