That’s right, it’s one D better! Actually, 4D printing is about using a 3D printer to produce self-reconfiguring, programmable material that intelligently arranges itself into basically any object — with no computers or electricity required! Skylar Tibbits, an MIT researcher, has already developed prototypes from his self-assembly lab. And this is just the beginning – from skyscrapers to space stations, the promises of 4D printing are amazing.
