Brand New 3D Printing Technique Grows Objects From Pool of Liquid
Most existing consumer-grade 3D printers print in layers that fuse together to make the final object. Carbon3D takes a different approach, by pulling a seamless object out of a pool of photosensitive resin. It’s entirely new breakthrough in 3D printing process. Watching it in action is also pretty impressing.
Carbon3D CEO and co-founder Joseph DeSimone, a chemical engineering professor at the University of North Carolina with more than 150 patents to his name, said he and his team were inspired by the T-1000 robot from Terminator 2, and what they created seems right out of science fiction.
Here’s how it actually works: A light shines through the pool of resin, which causes the resin to harden. Oxygen, on the other hand, causes the resin to liquify. Using them both in combination, a light source can be intricately controlled like a three-dimensional film projector, so only certain parts of the resin are pinpointed and hardened as the object is pulled out of the goo.[via qz.com]
