Microlattices make marvelous materials

Low-Density Materials![Figure][1] Macro scale octet lattice structure. PHOTO: RYAN CHEN/LAWRENCE LIVERMORE NATIONAL LABORATORY Framework or lattice structures can be remarkably strong despite their very low density. Using a very precise technique known as projection microstereolithography, Zheng et al. fabricated octet microlattices from polymers, metals, and ceramics. The design of the lattices meant that the individual struts making up the materials did not bend under pressure. The materials were therefore exceptionally stiff, strong, and lightweight.
