	Another 3D printer. It uses liquid resin which gets solidified using UV light rather than solid plastic which gets melted into a new shape. It's slower (each print takes a day or 2), dirtier, and requires more effort, but it promises more detailed objects and translucent objects, compared to the filament printer.		Another 3D printer.

			Delivery: USB stick. Place the resulting .pwms file in the root directory of the USB stick.
