Abstract

The study presents the results of research on the development of advanced high-tech aluminum alloy VAS1 for production of helicopter parts by selective laser melting (SLM). The effect of SLM process parameters on material quality, including microstructure, porosity and roughness has been investigated. Experimental data on the mechanical properties of the material in the as-built state and after strengthening heat treatment are presented. A prototype bracket-type part has been successfully fabricated meeting all geometric tolerances and being free from critical defects.
