According to the comments from the videos, ” 4D printing Programmable Textiles looks like, Lays potato chips are made. Once they’re produced on 3D printers, objects made of programmable materials continue to take shape, folding, unfolding or assembling themselves in response to outside stimuli such as light, movement, heat, pressure or water.
The programmable Materials consist of material compositions that are designed to become highly dynamic in form and function, yet they are as cost-effective as traditional materials, easily fabricated and capable of flat-pack shipping and self-assembly. These new materials include self-transforming carbon fiber, printed wood grain, custom textile composites and other rubbers/plastics, which offer unprecedented capabilities including programmable actuation, sensing and self-transformation, from a simple material”. 🙂
Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL). according to Stefanie Mueller, she is the X-Consortium Career Development Assistant Professor in the departments of Electrical Engineering and Computer Science and Mechanical Engineering,” Largely speaking, people are consuming a lot more now than 20 years ago, and they’re creating a lot of waste and by changing an object’s color, you don’t have to create a whole new object every time.”
“Appearance adaptivity, in general, is always a superior feature to have, and we’ve seen many other kinds of adaptivity enabled with manufactured objects,” says Changxi Zheng, an associate professor at Columbia University who co-directs Columbia’s Computer Graphics Group.
“This work is a true breakthrough in being able to change the color of objects without repainting them.”:)
