DOI: https://doi.org/10.3365/KJMM.2023.61.10.760

Abstract
In this study, AISI 316L stainless steels were manufactured by the L-DED process with various laser scanning speeds and laser powers, in order to analyze how volumetric energy density (VED) can affect their final shape, microstructure and mechanical properties. Under various VED conditions, it was found that a higher VED..... More
