Abstract

This study experimentally investigates the dependence of mechanical properties of an additively manufactured (AMed) FCCXYZ lattice structure on base materials of stainless steel 316 L, tool steel 1.2709, titanium alloy (Ti-Gr.2), and aluminum alloy (AlSi10Mg). Lattice structures with relative density (RD) from 0.11 to 0.36 show different compressive failure modes depending on the RD. A layer-by-layer collapse mode is observed at low RD, whereas a bulk failure mode is observed at high RD. A Gibson-Ashby model is developed to accurately forecast the performance of FCCXYZ lattice structures at different RDs. The discoveries presented in this study will be a valuable reference for designing an energy-absorbing component in metal AM.
