It's 2050, and you're prepping the oven to bake your next robotic minion while a 3D printer spews out its components. Wait a sec... bake a robot? As strange as that sounds, there's already a group of MIT researchers developing the technology and the printable materials that can self-assemble into a robot when heated. Since we usually bake food and not robots (and this is all very new), the researchers are experimenting with different materials to find the best option. One is aluminum-coated polyster that folds or twirls itself to form the proper components inside an oven. The other is PVC plastic sandwiched between rigid polyester sheets full of cuts and slits -- upon heating, the PVC becomes deformed and the slits close, forcing the whole thing to bend and fold into place.
