Abstract
A method for manufacturing a mechanical component by additive manufacturing which includes at least one layering sequence of depositing a powder material and locally melting and resolidifying the powder material. In each layering sequence, a solid layer of solidified material is formed, wherein the solid layers jointly form a solid body. An annealing sequence subsequent to at least one layering sequence includes, locally heating at least a region of the solid body in effecting a local heat input to the immediately beforehand manufactured solid layer which was formed by the immediately precedent layering sequence, with temperature being is maintained below a melting temperature of the material.
