This ultraviolet printer is 100x faster than ordinary 3D printers
by Emma Bryce
Regular 3D printers are just 2D printers on repeat, according to Californian chemist Jason Rolland. So his company, Carbon3D, created a machine that works up to 100 times faster than standard machines by "growing" objects out of a pool of resin.
Traditional 3D printers are too slow, Rolland says: they work by sandwiching individual layers on top of one another at a pace of just a few millimetres per hour. "Carbon3D takes your speed down from hours to minutes," says Rolland, the startup's vice president of materials. Carbon3D has developed a resin that can withstand high temperatures. "This gets us into industries like aerospace and automotive applications," he adds.
The company has patented its own method, continuous liquid interface production (CLIP), which relies on a balance of oxygen and UV light to liquify and solidify materials at precise points in the printing process. UV light rapidly solidifies resin, and oxygen counteracts the effect, ensuring that a thin liquid layer remains in the tray. To make the object, a small overhead platform dips into this permanently liquid source: as it pulls the resin out of the pool, the UV light solidifies it.
