Stainless steel can now be printed in complex 3D shapes but the polycrystalline microstructure is more intricate than achieved in traditional wrought materials. We are building micro-scale 3D simulation models of additively manufactured steels to study their mechanical properties. High-resolution electron backscatter diffraction (EBSD) images show spatial inhomogeneities in grain size, shape, and distribution of crystallographic orientations. This poster describes how we translate image data onto a lower-resolution 3D mesh that represents layers of additively manufactured steel while preserving the structure of spatial inhomogeneities to a substantial degree. Multiple realizations of crystallographic orientations on the 3D mesh are generated from a single sequence of EBSD images to support computational simulations of additively manufactured steel.
