The Zortrax robots are completely functional prototypes that were manufactured using their flagship 3D printer, the Zortrax M200. Zortrax caters to engineers and designers and will be coming out with more products in 2015. For more, check out this article: http://3dprint.com/19709/3d-printed-zortrax-robots/
