Abstract (en)

[origin: WO2023281176A1] The present document relates to a method (200) for additive manufacturing of a turbomachinery part, said part having a primary axis and at least one inclined portion extending in a secondary direction forming a non-zero angle with the primary axis, comprising the steps of: a) for each inclined portion: a1) providing (202) a target roughness of an outer surface of said inclined portion, a2) providing (202) a mechanical lowering of said inclined portion, a3) determining (204) a maximum roughness of the outer surface of said inclined portion depending on the mechanical lowering of said inclined portion; b) determining (206) an overall maximum roughness depending on the maximum roughness of the outer surface of each inclined portion; c) determining (208), depending on the overall maximum roughness, an orientation of the primary axis of the part to be manufactured with respect to a plane of a manufacturing platen of an additive manufacturing device; and d) producing (212) the part by additive manufacturing.
