摘要
The invention concerns a method of manufacturing objects by selective laser melting (SLM) in which between the forming of subsequent layers of the object a plastic deformation and residual stresses are induced into the solidified material of at least one of said layers to improve the mechanical properties and the fatigue life of the object. This step is carried out with a laser, as a LSP or WLSP step. The invention also concerns a system to carry out the method.
