In the paper there are shown the investigation results of the mode range of selective laser melting process in the course of which is achieved minimum porosity in samples grown from aluminum powder. The estimate of hardness in different areas of samples is carried out, a single melted track formation is considered. The results have practical significance for the growth aluminum alloy products with the specified structure.
