Abstract (en)
[origin: WO2021198598A1] The invention relates to a method for the additive manufacturing of a wall (10) for a turbine engine, the wall (10) comprising a first cooling aperture (40). The manufacturing method comprises the additive manufacturing of the wall (10) by selective melting or selective sintering on a powder bed. The wall (10) is manufactured at least partially around the first cooling aperture (40) with at least one lower region (19a) that has a minimum length (La) of between 0.01 and 0.4 mm and/or with a lower region (19a) that has a total thickness (ea) of between 0.06 and 0.22 mm.
