Using components made from smart shape-memory materials with slightly different responses to heat, researchers have demonstrated 4D printing technology that allowed creation of complex self-folding structures. The technology, from Georgia Institute of Technology and Singapore University of Technology and Design (SUTD), could be used to create 3D structures that sequentially fold themselves from components that had been flat or rolled into a tube for shipment...
