A simple snap-fit and vacuum brazing method has been developed to fabricate three dimensional space filling octet-truss lattice structures from Ti–6Al–4V alloy sheets. Using strut lengths of 7–25mm resulted in a relative density of the lattices ranging from 2% to 16%. The lattice elastic stiffness c...
