Abstract
A method for laser additive manufacturing of a mechanical part includes providing a laser beam the operation of which will be controlled by a computer into which is introduced a CAD computer file which is cut into one or more strata which, once superimposed, allow to form the structure of the desired mechanical part, disposing a substrate in a manufacturing enclosure wherein an atmosphere of a neutral gas is created, depositing on the substrate at least a first layer of a powder of a first metallic material to be melted, levelling the first layer, subjecting by means of the laser beam the first layer to a selective melting step, if necessary, depositing on the substrate a second layer, levelling the second layer and subjecting this second layer to a step of selective melting, removing the excess material and cleaning the assembly and subjecting the part to finishing operations.
