Traditional 3D printers requires the printer to add layer after layer of material via multiple passes to create a 3D object. This process is highly time consuming and also leaves traces of each layer. This cool new terminator style printer grows an object out of a pool of liquid which uses ultra violet light and oxygen to cure or prevent the curing of the resin. The company claims that the printer prints 25 to 100 times faster than a traditional 3D printer.
