Remember those tiny sponges that expand when exposed to
water? Well, this concept is used in the
new idea from MIT, which they call it “4-D printing”. This printer creates strands that can be
molded into anything you want to. When
these strands are exposed to water, the strands can be folded into various
shapes based on the placement of the materials.
It can also be folded into other shapes, not just the desired one. The creator
and director of MIT’s Self-Assembly Lab, Skylar Tibbets, said that this can be
used in architecture and other fields. Wouldn't it be nice to see a building itself?
