The object of the study was 316L steel obtained by the method of selective laser melting (SLM). The structure of 316L steel was investigated after different SLM modes. The effect of different SLM modes on the second phases precipitation after heat treatment was studied. It is revealed that the fraction of precipitates of the χ-phase correlates with the energy density of the laser beam during SLM.
