Additive Manufacturing (AM) technologies provide new opportunities to enhance some piece-producing processes in the industry: AM offers the possibility to produce complex-shaped parts, and microstructures from Laser Powder Bed Fusion (LPBF) can heavily differ from microstructures usually obtained through traditional processes. In this work, several LPBF preforms were constructed along different directions and then cold rolled at different deformation rates. Two 316L powders that produce two different microstructures were used: one exhibiting columnar grains and the other equiaxed ones. These two obtained microstructures were studied by EBSD, along with a study focused on the tensile properties. The first results show that the LPBF 316L is ductile while being more resistant than the traditional 316L. Furthermore, the material deformation is mostly due to mechanical twinning, which is similar compared to the standard 316L. The final goal of this study is to analyse the potentialities of combining LPBF and traditional manufacturing processes.
