Abstract
The invention relates to a process for manufacturing a part () comprising a formation of successive solid metal layers (), superimposed on one another, each layer describing a pattern defined from a numerical model (M), each layer being formed by the deposition of a metal (), referred to as a filler metal, the filer metal being subjected to an input of energy so as to melt and constitute, by solidifying, said layer, wherein the filler metal takes the form of a powder (), of which the exposure to an energy beam () results in a melting followed by a solidification in such a way as to form a solid layer (), the method being characterized in that the filler metal () is an aluminum alloy comprising at least the following alloying elements: The invention also relates to a part obtained by this method. The alloy used in the additive manufacturing method according to the invention, makes it possible to obtain parts with remarkable mechanical performance, while still obtained a method of which the productivity is advantageous.
