Post processing operations in selective laser melting (SLM) are becoming increasingly important to be able to have components with maximum performance. With this paper, the authors present the first results relating to microstructural modifications obtained after a femtosecond laser shock peening treatment (f-LSP) with a pulse duration of 165 fs and energy per pulse varying between 200-600 μJ. The samples produced with SLM were obtained by varying both the energy and scanning parameters and the surfaces treated with f-LSP are both parallel and orthogonal to the build direction.
