New Liquid 'Terminator Style' 3D Printer Could Print 10x Faster

3D printing has always been something that has appealed to people but the time it takes to actually print an object can be so long that people just don't have enough interest to do it.
Generally 3D Printers work by depositing a layer of material much like a standard printer would, but then it prints out another layer once the material below once it has become a solid/cooled. Typically it takes hours for full objects to be printed via this method.
However, recent research has made advances by using the benefits of Oxygen. The technique, called CLIP (Continuous Liquid Interface Production), exploits photochemistry rather than the layering approach that is typically used in 3D Printers.
Inspired by Terminator 2, The new 3D printer starts with a basin filled with liquid resin. Then Ultraviolet rays can emerge from beneath. It is similar to coming up from the bottom in a pool.
From the hole between the basin and ultraviolet rays is a layer of oxygen-rich liquid, just tens of micrometers thick. This layer serves as a transparent window for the ultraviolet rays.
Then for printing, a metal plate is lowered down onto the surface of the resin pool. Ultraviolet rays are then fired like a shooting star. The resulting solid object is attached to the metal plate. When enough of the object has solidified, the 3-D printer slowly pulls the metal plate upward. The hardened item rises from the liquid resin, it creates suction forces that pull liquid resin into the basin to replace what was lost to the solidified object.
“By rethinking the whole approach to 3D printing, and the chemistry and physics behind the process,” explains DeSimone, Carbon3D's head Chemist “we have developed a new technology that can create parts radically faster than traditional techniques by essentially ‘growing’ them in a pool of liquid.”
With the new approach, time wise, it creates more than 1 meter per hour, generating complex solid objects. By slowing down print speeds, they could also print features less than 100 MicroMetres wide, or thinner.
Carbon3D plans to put this product on the market by the end of 2015.We encourage all readers to post their thoughts and opinions on our articles.
