METHOD FOR PERFORMING SELECTIVE LASER MELTING OF METAL POWDER

摘要

A method for performing a selective laser melting of metal powder to manufacture an object (10), comprises the following steps: scanning a metal powder bed by means of a laser beam configured to complete a plurality of melting paths (D) so as to build a plurality of confinement sections (1,3,5,7) each having its own predefined width, said confinement sections (1,3,5,7) delimiting between them a confinement space (C) having a predefined width; scanning a metal powder bed by means of a laser beam configured to complete at least one melting path (P) within the confinement space (C) so as to selectively melt the material present in said confinement space (C) in order to build an intermediate section (2,4,6) having a predefined width.
