In nature, cellular solid structures are highly prevalent. Among these, lattice structures represent significant advancements in engineering due to their excellent mechanical properties and absorption capacity. The objective of this work is to assess the energy absorption capabilities of 3D-printed BCC and W-BCC lattices through impact testing. These lattices will serve as cores for composite sandwich structures. Experimental evidence reveals that absorption capacity is closely dependent on the morphology of the sample; notably, W-BCC samples with larger strut diameters exhibited enhanced impact resistance.
