In this study, a progressive additive virtual printing technology developed using Simulia/Abaqus was used to conduct a part-scale additive analysis to study the additive anisotropy properties of Hastelloy X materials. First of all, using the PBF method, cantilever specimens for getting the equivalent Eigen strains and tensile specimens for each building direction were fabricated. Then, deformation was measured by cutting the as-built cantilever specimen and a methodology for obtaining the equivalent Eigen strain with the deformation results was presented. Using the obtained equivalent Eigen strain, additive virtual printing analysis was performed in step 1, support cutting analysis was performed in step 2, and tensile analysis was performed in step 3 to compare the results of tensile tests according to each stacking direction. The phenomenon of higher strength in the horizontal direction than in the vertical direction was explained as the compressive residual stress of the in-plane Eigen strain. And the phenomenon in which the strength was reversed compared to the wrought model in the additive analysis in each direction was also explained by the Poisson effect due to the in-plane compressive stress.
