MIT scientists unveil "4D printing" for self-assembly at TED conference

3D printing has risen in popularity ever since RepRap introduced their ‘Darwin’ model for the consumer market back in 2007. They’re excellent for fast prototyping and manufacturing just about anything we can imagine and don’t require remortgaging the house to own one. Not satisfied with simply creating objects quickly, a team of engineers, led by Skylar Tibbits, from the MIT Self-Assembly Lab (along with Stratasys) have taken the idea of 3D printing to the next level with 4D which allows the objects created to assemble themselves over a period of time. To get their objects (simple shapes at this point) to assemble themselves the computer engineers used standard (unknown at this time) plastic they combined with ‘smart’ material that transforms and expands when subjected to water. According to Tibbits, the rigid plastic material forms the structure while the other layer beco...
