Abstract

L'invention concerne un procédé de fabrication d'une pièce par fusion sélective de lits de poudre par faisceau de haute énergie comprenant les étapes suivantes : (a) On fournit un matériau sous forme de particules de poudre (60), (b) On dépose une première couche (10) de poudre du matériau sur un support de construction (80), (c) On balaye au moins une région de la première couche (10) avec le faisceau (95) de haute énergie de façon à chauffer localement la poudre de cette région à une température supérieure à la température de fusion de cette poudre, de telle sorte que les particules de la poudre ainsi fondue forment au moins un premier élément (15) d'un seul tenant, (d) On dépose une deuxième couche (20) de poudre sur la première couche (10), (e) On balaye une région de ladite deuxième couche (20) par le faisceau (95) de façon à chauffer la poudre de cette région à une température supérieure à la température de fusion de cette poudre, de telle sorte que les particules de la poudre ainsi fondue forment au moins un deuxième élément (25) d'un seul tenant, (f) On répète les étapes (d) et (e) pour chaque nouvelle couche de poudre à déposer au dessus d'une couche précédente dont une région a déjà été préalablement fondue, et ce jusqu'à la formation complète de la pièce. Les étapes (b) à (f) sont réalisées à l'intérieur d'une enceinte de fabrication (100) étanche dans laquelle règne une dépression de gaz.The invention relates to a method of manufacturing a part by selective melting of powder beds by high energy beam comprising the following steps: (a) providing a material in the form of powder particles (60), (b) deposits a first layer (10) of powder of the material on a construction support (80), (c) At least one region of the first layer (10) is swept with the high energy beam (95) so as to heat locally the powder of this region at a temperature above the melting point of this powder, so that the particles of the powder thus melted form at least a first element (15) in one piece, (d) A second layer (20) of powder on the first layer (10), (e) A region of said second layer (20) is swept by the beam (95) so as to heat the powder of this region to a temperature above the melting temperature of this powder, so that the particles of the powder have If molten form at least one second element (25) in one piece, (f) Steps (d) and (e) are repeated for each new layer of powder to be deposited on top of a previous layer, one region of which has already melted, until the complete formation of the part. Steps (b) to (f) are carried out inside a sealed manufacturing enclosure (100) in which there is a gas depression.
