Abstract
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.
