Abstract
The process of manufacturing thin walls using selective laser melting (SLM) from aluminum alloy powder AlSi10Mg was studied. The research aims at specifying a type of lattice structure based on skeletal-triple periodic minimal surface (TPMS) and sheet-TPMS shells. In this regard, the possibility of obtaining well-quality thin walls was studied. The accuracy of manufacturing, surface roughness and porosity of the samples were taken as quality criteria. The dependences of the influence of SLM parameters on the geometric characteristics, roughness, and porosity of thin walls were obtained. The preferential parameters for manufacturing thin-walled aluminum alloy samples have been determined. The microstructure and phase composition of the studied alloy after SLM were studied.
