Foldable 3-D solid structure
Hirotaka Nakayama and Tomoyoshi Ito, et. al., developed a method for creating a strong structure that changes from 2-D mode into 3-D mode. The deformation is reversible. This structure is formed from four planar components that can be made with a printer. By using the proposed technique, 3-D objects thought to be generally difficult, such as a globe or a spheroid, can be built using sheet materials, such as paper. Our proposed method allows mass production, and the created objects are very portable. This technique can be applied to various fields, and we present several applications: consumer character goods, packaging, educational materials, emergency tents, and spacers for laparosopic surgery.
