MIT's 3D printed 'peel-and-go' structures can fold themselves

MIT researchers have developed a technique for 3D printing expanding polymers that self-fold without heating or water. The technique could be used for printed electronics and, someday, to make 3D printed robots. If you 3D printed an object and it immediately folded in on itself on the print bed, you’d probably be worried. Did I use the wrong filament? Is there crazy humidity in the air? Am i seeing things? But for a group of MIT researchers, self-folding 3D printed structures could be incredibly useful. The researchers, who are developing a 3D printing technique for self-folding structures, say that […]
