Summary: The study on EBM-produced Ti-6Al-4V functionally graded materials (FGM) found that FGM exhibit progressive layer-by-layer deformation mode regardless of unit cell designs and build direction, making them favorable for uni-directional impact absorption applications. Compared to uniform density counterparts, FGM show superior energy absorption, with further improvement achieved by changing the build direction. Lattice structures with lower relative density have the potential to outperform those with higher relative density by altering unit cell design or density profile.
