摘要： A laser treatment system and method for imparting beneficial residual stresses into a desired part during production thereof by a Selective Laser Sintering or Melting (SLS/SLM) process, the method including repeatedly subjecting the part to an in-situ Laser Shock Peening (LSP) treatment during the SLS/SLM process. The in-situ LSP treatment includes selectively bringing an LSP module in contact with a surface of the part during the SLS/SLM process, and subjecting the LSP module to the action of a first laser beam to impart beneficial residual stresses into the part. The LSP module is movable between a building chamber where the part is being produced for the purpose of carrying out the in-situ LSP treatment, and a separate storage chamber when the LSP module is not used for the purpose of carrying out the in-situ LSP treatment. The invention is also implementable in a corresponding additive manufacturing system and method.

摘要： A method for manufacturing an object including the steps of forming layers by adding successive layers of material to form the object by selective laser melting (SLM), and inducing plastic deformation and residual stress into solidified material of at least one of the successive layers of material to improve mechanical properties and a fatigue resistance of the object, wherein the plastic deformation and the residual stress are induced by a laser.
