4D Printing Self-Building Space Stations!

Forget 3D, 4D is the future! The kinks are still being worked out, but this new technology could transform life here on Earth, and even outer space. Anthony tells us how.

"Next, 4-D Printers?"
"Now that the promise of 3-D printing has landed on the national agenda, researchers want to increase the stakes — with so-called 4-D printing."
"4D printing sees materials form themselves into anything"
"There are 3D printers that build things up, adding one sliver of plastic at a time, and 3D mills that tear things down, grinding away one small chunk at a time. But Skylar Tibbits offer a very provocative alternative: technology for 3D printing where the chunks start separated and intelligently arrange themselves into basically any object."
"Skylar Tibbits: Can we make things that make themselves?"
"MIT researcher Skylar Tibbits works on self-assembly -- the idea that instead of building something (a chair, a skyscraper), we can create materials that build themselves, much the way a strand of DNA zips itself together."
