TOOL FOR MANUFACTURING A PART BY SELECTIVELY MELTING A POWDER

摘要

An installation for fabricating a part by selectively melting powder, the installation including a mechanism producing a beam, for example a laser beam or an electron beam, and a mechanism moving a point of impact of the beam over a layer of powder. The installation further includes a collector element for collecting projections of molten powder produced during local melting of the powder by the beam, the collector element including an opening for passing the beam, and a mechanism configured to move the collector element jointly with the beam over the layer of powder.
