Abstract

L'invention concerne un procédé de fabrication d'une pièce métallique (1) comprenant au moins les étapes suivantes : la formation (étape E1) d'une ébauche (10) de la pièce sur un support (20), la pièce brute étant formée couche par couche à partir d'une poudre métallique par un procédé du type fabrication additive, la pièce brute comprenant une partie utile (1) correspondant à la pièce à fabriquer et une portion sacrificielle (14, 16 ; 14', 16') s'étendant entre le support (20) et la partie utile, et la séparation (étape E2) de la partie utile (1) de la pièce brute (10) ainsi formée du support (20). L'étape de séparation de la partie utile de la pièce brute du support comprend la découpe au jet d'eau de la portion sacrificielle de la pièce brute.The invention relates to a method of manufacturing a metal part (1) comprising at least the following steps: forming (step E1) a blank (10) of the part on a support (20), the blank being formed layer by layer from a metal powder by a process of the additive manufacturing type, the blank part comprising a useful part (1) corresponding to the part to be manufactured and a sacrificial portion (14, 16; 14 ', 16') extending between the support (20) and the useful part, and the separation (step E2) of the useful part (1) from the blank (10) thus formed from the support (20). The step of separating the useful part of the blank from the support comprises the water jet cutting of the sacrificial portion of the blank.
