A metal part with a wall thickness less than 5 mm includes a preform made from a flexible composite sheet, a flexible composite sheet segment, and an appended insert including a fastening portion that is sandwiched between a rear end of the preform and the flexible composite sheet segment. The flexible composite sheet segment encloses the fastening portion of the appended insert.

Method for making a metal part with a complex geometry with a thin wall

A method for additively manufacturing a part of a nacelle of an aircraft propulsion unit such as an exhaust conduit portion a step of depositing a compound including a TiAl-based powdery intermetallic alloy and consolidating the compound by sintering, without melting the compound.

Additive manufacturing process of a part for an aircraft propulsion unit nacelle

A method for producing a thin-walled metal part with complex geometry includes mixing a metal powder with a polymer binder in order to obtain a composite mixture, producing a flexible composite sheet from the composite mixture, cutting, in the flexible composite sheet, a preform based on a contour of the metal part, applying the preform in a mold having a surface configured with a relief of the metal part, and debinding and sintering the preform in order to obtain the metal part.
