TOOLING FOR MANUFACTURING PARTS THROUGH SELECTIVE FUSION OR POWDER BED SELECTIVE SINK, AND ASSOCIATED METHOD

摘要

The invention relates to a tool (1) for the manufacture of a workpiece (4) by a selective melting process or selective sintering on a powder bed, comprising: a production plate (8) having a working surface (8b) a laser source (10) capable of emitting a laser beam (10a) of predefined wavelength towards the work surface of the production plate, and a protective element ( 11) covering the work surface and made of a material transparent to the wavelength of the laser beam, said protection element having a horizontal face (11a) opposite the working surface. The invention also relates to a method implementing such tooling.
