Abstract

The article deals with the study of verification and evaluation of selected mechanical properties of stainless steel 316L (1.4404) after the production of additive technologies (3D printing) by Selective Laser Melting (SLM). For the purpose of the experimental testing were printed two sets of samples from the powder metal by the laser-sintering process at different process parameters. The main difference was in the power of laser for first set was determined half power 200 W and for second set maximum power of 400 W. The machine printed samples were further divided into two sets, one of which has been heat treated by annealing the second set was not thermally affected. Making the test samples were realized on Renishaw AM 400. The investigated parameters were the results of mechanical tests of specimens after the tensile test according to EN 10002-1: 2001 and impact strength test by Charpy according to ISO 148-1.
