This paper shows the residual stress distributions over the depth of a dice out of 1.2344 produced as an additive structure. Because of the layer structure (obtained by SLM) it gives two interesting directions (along with the layer and perpendicular to the layer) to be investigated concerning residual stresses. Next a deep rolling process was done. Deep rolling gives different residual stress distribution. Perpendicular to the rolling track higher compressive residual stress is induced in comparison along the track. Combined with the layer structure of the dice, four different combinations are obtained that are investigated concerning residual stresses.
