It is also capable of being a CNC, laser cutter, laser engraver, drawing machine, and paste 3D printer. The kits are 1000 Euros and if you want to build it from scratch, it can be done for around 600 Euros. There is also the option of building or buying the Hello Super Printer which features dual build platforms. Read more about this new RepRap at http://3dprint.com/13298/hello-printer-reprap-3d/
