In the work the varieties of additive technologies, their advantages and disadvantages were analyzed. The experiments on selective laser melting (SLM) are described in more detail in order to provide the required microstructure of the synthesized material. The modes that provide stable printing of a single layer were experimentally established. The optimal values of scanning speed and laser power for the alloy Inconel 718 were determined. 12 Ref., 6 Figures.
Keywords: SLM process, alloy Inconel 718, laser power, single track, specific volume power, maximum layer density
