Inherent strain based estimate of the residual deformations for printed MS1 and 316L parts

Abstract

In this study, the effect of the magnitude of inherent strain is examined for the simulated deformations of printed specimens, where the material grade is either of MS1 or 316L steel powders. While both material qualities are steel grades, and the same sets of inherent strain values with different magnitude and directional variations are defined in the simulations, allowing isotropic and orthotropic behaviour too, the resulting deformation in the printed part may also be strongly influenced by the mechanical properties of the different steel grades.
