Abstract
Selective laser melting (SLM) technology allows the manufacture of geometrically-complex parts, including aluminum alloys, which can find their application in various industries. To provide high performance products, an important task is to obtain dense (with low content of defects), fine structure of the material. One possible solution is the choice of the optimal modes of production parts using SLM. The article presents the results of a study of the influence of SLM process parameters on the porosity of the synthesized samples of aluminum alloy system Al–Si–Mg. Shows the change in the structure depending on the energy density, scan speed, distance between the tracks and laser power.
