The world of 3D printing seems very promising, and not only plastic parts are obtained, but also food and even functional organs. However, when you put yourself in front of a normal 3D printer in operation, you discover that the most striking of all it's his tremendous slowness.
This may change shortly thanks to the development of CLIP (Continuous Liquid Interface Production), a project by a group of researchers from the University of North Carolina at Chapel Hill. Instead of printing the piece layer by layer, CLIP "cultivates" the piece using ultraviolet light and a liquid medium. In addition this process would be 25 times faster than the traditional one.
How does it work? You can take a look at the two videos that accompany this post, and also the explanation they offer from NeoTeo:
The 3D printer has a tray filled with liquid resin. At the bottom, a membrane allows the passage of oxygen and ultraviolet light. Oxygen blocks the normal curing process in the resin, thus generating a dead zone that never hardens. Then, the ultraviolet light begins to reproduce the piece (divided into sections) just above the dead zone, at the same time that a special arm raises the impression, slowly removing it from the resin.
