Description
Summary:Selective laser melting (SLM) technology, which exhibits high printing resolution capacity, in used in order to prepare objects with cellular structures corrosion-resistant steel (316L). Cellular structures are considered as promising elements for topological optimization with the aim of reducing weight and giving an object special properties. The effect is studied in this work of strategies for laser beam scanning on an object being formed with a cellular BCC structure of steel 03Kh16N15MZ during SLM in an SLM280 unit. It is shown that depending on production regimes for object preparation with these structures there are changes in cellular structure strut minimum diameter, nature and distribution of defects, and mechanical properties.
