An earlier metallic tube lattice produced hollow tube nickel microlattices with a density of.9 milligram per cubic centimeter and complete recovery after compression exceeding 50% strain with energy absorption similar to elastomers. Young's modulus E scales with density as E ~ ρ2, in contrast to the E ~ ρ3 scaling observed for ultralight aerogels and carbon nanotube nanofoams with stochastic architecture. Hardness of 6 GPa and a modulus of 210 GPa were measured by nanoindentation and hollow tube compression experiments, respectively. These materials are fabricated by starting with a template formed by self-propagating photopolymer waveguide prototyping, coating the template by electroless nickel plating, and subsequently etching away the template.
