Abstract
The work presents a noble orbital hybridization-inspired tessellation approach for lattice structures, which may modify the characteristics of a lattice. The strategy organizing lattice unit cells according to sp, sp2, sp3, and sp3d2 hybridization patterns. Material extrusion (MEX) was employed to manufacture the tessellated structures, and it was investigated using static and dynamic loads. The sp3-inspired tessellation displayed the greatest energy absorption and revealed two separate failure modes: layer-wise and layer-coupled cell failure. The sp3-inspired tessellated structure displayed the greatest modulus and plateau stress. The current approach was effectively employed to modify the static and dynamic mechanical characteristics of lattice unit cells.
