Anisotropy of Mechanical Properties and Residual Stress in Additively Manufactured 316L Specimens.

In the presented study, LPBF 316L stainless steel tensile specimens were manufactured in three different orientations for the analysis of anisotropy. The first set of specimens was built vertically on the build platform, and two other sets were oriented horizontally perpendicular to each other. Tensile test results show that mean Young's modulus of vertically built specimens is significantly less then horizontal ones (158.
