3D printers come in all different sizes, but the LumiPocket may just be the smallest yet. It is a DLP printer that is capable of printing up to 3 different objects at once using 3 different colors/materials. It does this by using 3 separate VATs but only one DLP projector. It is currently on Indiegogo, and they are looking to raise $50,000. The price without a projector starts at $379. Read more at: http://3dprint.com/17868/lumipocket-dlp-3d-printer/
