Origami modules make large structures about 3.5 times stiffer

MIT researchers turned Ron Resch's folded tessellations into computably designed rigid modules. An automated solver breaks a target shape into foldable cells, CNC machines cut them from flat sheets such as aluminum, and builders fold and connect them with hand tools instead of large welding equipment. The units naturally settle into their only valid configuration during assembly. Simulations indicate about 3.5 times the stiffness of some structural-origami approaches while using roughly two-thirds as much material. A team without professional construction experience also assembled a 23-foot aluminum hanging structure in a few days. Potential uses include disaster shelters, aircraft and modular-robot parts, acoustic panels and facades. Evidence comes from simulations, prototypes and an exhibition-scale structure, not long-term compliance with building codes, wind, fire or extreme environments.
