Mechanical performance of a node reinforced body-centred cubic lattice structure manufactured via selective laser melting

In most previously constructed lattice inspired structures, atoms were not included. Thus, their mechanical behaviours might not well simulate the lattice structures. In the present work, a body-centred cubic (BCC) inspired structure with atoms as reinforced nodes and atomic bonds as connected struts, was additively manufactured using Ti-6Al-4V alloy via a selective laser melting. Results of mechanical compression test and finite element analysis revealed the higher yield strength, collapse strength and energy absorption capability of the BCC-inspired structure with reinforced nodes than the ones without reinforcement.
