This thesis work aims to investigate the possibility to use selective laser melting (SLM) to produce electric cores for a traction electric motor. SLM is a powder bed based additive manufacturing (AM) technique that guar- antees relative structural density of the build part > 99%. This is one of reasons why SLM is among the most interesting processes to research on in the field of electric motors produced by AM. However, this technique is also chacaterized by high residual stress because of the high and repeated temperature gradients during the construction making it similar to a laser welding process. The prediction of residual stress is conducted in this study by performing a thermal-to-structural Finite Element Analysis (FEA) on a commercial software for additive processes ( ANSYS Workbench) on one material available in its library (316 stainless steel).
