Importance of microstructure modeling for additively manufactured metal post-process simulations

•Influence of 3D SLM microstructure induced anisotropy on milling and laser peening.•SLM microstructure inhomogeneity reveals expanded temperature/plastic strain fields.•Shear and ductile damage progression rates in milling vary due to SLM inhomogeneity.•Asymmetry in residual stress clearly evident...
