Selective laser melting is one of the modern methods of manufacturing parts in the production of machine-building equipment, a special place is occupied by complex technological processes used in the manufacture of high-load units of pneumatic-hydraulic system from heat-resistant alloys. The studies were performed on samples made of powder material AISI 316L stainless steel martensite class. Tests to determine the mechanical properties were performed in accordance with ISO 6892 on an INSTRON test machine. The control of the surface roughness was performed using a BioBase device. From microstructural analysis and testing the method of registration of macrolocalization fields of the working zone samples, it was found that the destruction began from the surface of the samples from the microconcentrators due to different roughness.
