Mind-Blowing 3D Printing Technique is Inspired by Terminator 2 Weekly Tech. 5

3D Printing ?!

An iconic scene from the movie "Terminator 2," the robotic villain T-1000 rises fully formed from a puddle of metallic goo. From this very scene is where the company Carbon3D received their inspiration to think of their 3D printing technique. Just as the evil T-1000 rises from its puddle of metal alloys, objects from the new printer seem to ooze into existence from the ether. They come out 25 out of 100 times faster than anything on the market now according to the study published in science. This new process to DeSimone and his colleagues is called "CLIP". CLIP places a pool of resin over a digital light projection system, where a special window is placed between the resin and allows light and oxygen to travel through (much like contact lenses). To create an object CLIP projects specific bursts of light and oxygen, in which lights hardens the resin and the oxygen keeps it from hardening. By controlling the light and oxygen exposure in tandem, intricate shapes and latices can be made in one piece instead of many layers of material that usually make up a 3-D printed object.
