In this study, an AlSi10Mg alloy was produced via selective laser melting (SLM), an additive manufacturing method, with different production parameters. The grid scanning method was preferred for manufacturing, and 18 samples were produced with 3 different laser powers and 3 different scanning speeds with 2 different hatch spaces and constant layer thickness. The Etial-171 alloy, cast AlSi10Mg, produced by the Eti aluminum company was used for comparison. Energy density values were calculated according to production parameters, and hardness values were measured for 19 samples. As a result, the highest hardness value was 101 HB at a 300 W laser power, 2000 mm/s scanning speed, and 0.1 hatch space with a 50 J/mm3 energy density. This value is 35% greater than the hardness of the AlSi10Mg produced by casting.

摘要

In this study, an AlSi10Mg alloy was produced via selective laser melting (SLM), an additive manufacturing method, with different production parameters. The grid scanning method was preferred for manufacturing, and 18 samples were produced with 3 different laser powers and 3 different scanning speeds with 2 different hatch spaces and constant layer thickness. The Etial-171 alloy, cast AlSi10Mg, produced by the Eti aluminum company was used for comparison. Energy density values were calculated according to production parameters, and hardness values were measured for 19 samples. As a result, the highest hardness value was 101 HB at a 300 W laser power, 2000 mm/s scanning speed, and 0.1 hatch space with a 50 J/mm3 energy density. This value is 35% greater than the hardness of the AlSi10Mg produced by casting.
