 This study uses finite element analysis, FEA, to investigate the mechanical performance of lattice structures fabricated using laser powder bed fusion, LPBF, for aerospace, automotive and biomedical applications. The results show that while the elastic modulus is well predicted by both simulation methods, the yield strength is highly underpredicted. Further analysis with uniform lattice structures with varying porosity reveals agreement with the Gibson-Ashby model. To improve prediction accuracy, more information on defect conditions is needed.
