The subject of the paper is finding optimal setting of the laser power for the utility properties of the surface roughness parameter in the Additive technology by SLM method for differently large overhangs. The overhangs created on the sides, which are not supported by a supporting structure and are not designed in any way for printing by Additive technology. The samples were printed from stainless steel 316L (1.4404) under constant building parameters with change only of laser power. In total three laser power sizes were tested on differently large overhangs. The surface roughness parameters were measured and evaluated on the lower side of the overhang. The quality of the surface roughness parameter shows the suitability of overhangs in cases where it is not possible to add supporting construction. In conclusion, the most appropriate laser power was determined in relation to the size of the overhang and its surface roughness parameter.Keywords: laser power, SLM, overhang, angles, stainless steel
