Popis:	By selective laser melting, samples were synthesized from the powder material of the AlSi10Mg alloy. All samples are made of aluminum alloy metal powder. Granulometric analysis data and particle morphology were studied to determine the suitability of the powder used in the selective laser melting. To identify structural defects, the samples were polished from the end and from the side of the building platform. Using a metallographic microscope, the porosity of samples made at a flow rate from 7.28 * 105 to 2.23 * 106 was analyzed. The geometric shape matching of the initial three-dimensional model was analyzed using the holes in the samples as an example. The results of particle size analysis, sphericity of particles of powder material, as well as metallographic analysis of samples can be used to improve the performance of parts obtained from AlSi10Mg aluminum alloy by selective laser melting.
