A recent graduate of Umeå University has created the Hangprinter, a 3D printer that, well, hangs. It's essentially just the printer mechanism, anchored only by strings that attach to walls, ceilings, or any other surface, meaning that it can be easily set up to print anywhere - and at any size. Without the confinement of a box or even rails, the Hangprinter has an unlimited build volume, as it's currently demonstrating at Sliperiet, Umeå Arts Campus. As part of the +Project innovation initiative, the Hangprinter is in the process of 3D printing a Tower of Babel. The printer's creator, Torbjørn Ludvigsen, is a RepRap expert and has made the Hangprinter fully open-source. Read more at 3DPrint.com: http://3dprint.com/167250/hangprinte...ir-3d-printer/
