Beschreibung
Zusammenfassung:	The invention relates to a method for producing, by additive manufacturing, a part comprising at least one surface (61; 63) that must be held during the manufacturing, said method including: a step of forming a raw part by additive manufacturing, said raw part comprising a support (64) including a pillar (66) and a head (67) which is an alveolar element connecting the pillar (66) to the surface to be held (61, 63); and a step of detaching the support (64) from the rest of the raw part. L'invention concerne un procédé d'obtention par fabrication additive d'une pièce comportant au moins une surface (61; 63) devant être soutenue durant la fabrication, incluant: -une étape de formation par fabrication additive d'une pièce brute comprenant un supportage (64) incluant un pilier (66) et un chapiteau (67) qui est un élément alvéolaire raccordant le pilier (66)à la surface à soutenir (61; 63); -une étape de désolidarisation du supportage (64) du reste de la pièce brute.
