A module for an aircraft turbine engine including at least one annular casing of an annular combustion chamber, at least one sealing ring for a turbine wheel, and at least one annular bearing support, wherein this module is made in one piece.

Module of an aircraft turbine engine

A method for producing, by additive manufacturing, a part including at least one surface that must be held during the manufacturing, the method including: a step of forming a raw part by additive manufacturing, the raw part including a support including a pillar and a head which is an alveolar element connecting the pillar to the surface to be held; and a step of detaching the support from the rest of the raw part.

Optimization of supports for the additive manufacturing of a component

A method for obtaining, by additive manufacture, a component including at least one recess, this method including: a step of forming, by additive manufacture, a one-piece blank component, in which the at least one recess contains a support including a core in the form of a block of material and cellular elements that connect the core to the recess; and a step of detaching the support from the rest of the blank component in order to expose the recess.

Method and apparatus for optimisation of the supports for the additive manufacturing of a component with a recess

A bearing support for an aircraft engine, manufactured, in one piece, by powder-bed additive manufacturing from a manufacturing platform, including a cylindrical element including an annular stiffener with a cross-section that changes along its circumference, this stiffener being formed with alternating portions having a &#x393;-shaped cross-section, needing to be supported during the manufacture, and portions having a Y-shaped cross-section that are not supported during the manufacture.
