description: To create metal products, various processing technologies are used, which include foundry, cutting, pressure processing, various types of welding, and 3D printing. 3D printing technology is the most modern method of metal processing, which allows using special laser printers to produce metal products of any shape, including products with complex configurations. Steel 20Ð¥13 belongs to the martensitic class steels, is corrosion-resistant, heat-resistant and can be welded. The indicated characteristics of the material in question make it possible to successfully use it for the manufacture of products of complex shapes in various industries and, in particular, in the military. In this work, the porosity of samples of 20Ð¥13 steel material created by selective laser melting (SLM) technology for the further production of parts of complex geometric shapes was investigated. Based on the results of the studies, the dependence of the porosity of a product produced by additive selective laser melting (SLM) technology on energy density was obtained, which is advisable to use to further establish the most effective operating mode of the laser.
