Single-Sheet Model Chair

cults3d

This chair uses Lamina Emergent Torsion (LET) joints to fold from a single sheet into a full structure. With about an hour to print and a few drops of super glue, you can make a scale model of our full-sized plywood chair! LET joints use the bending of individual torsion bars to gain bending and translational motion from previously solid sheets of material. This makes it so we can gain large deflections from materials that do not generally bend, such as wood.
