metalattice
Metallattice refers to lattice structures fabricated from metal or to the crystalline lattice of metal elements. In engineering and materials science, metallattices commonly describe engineered, porous networks made from metal that provide a combination of lightness, stiffness, and energy absorption. They are used at macro scales (3D-printed metal lattices) and, less often, as descriptions of atomic lattices in metals.
Macro-scale metallattices use repeating unit cells such as octet-truss, cubic, or kelvin cell geometries. The choice
Fabrication is dominated by metal additive manufacturing techniques such as laser powder bed fusion (DMLS/SLM) and
Properties of metallattices are highly tunable: they exhibit high strength-to-weight ratios, controlled energy absorption, and anisotropic
Applications span aerospace, automotive, medical implants (porous metallic scaffolds promoting bone ingrowth), sports equipment, and heat
