NDSU makes progress towards fully self-replicating 3D printer for space exploration

One of the most interesting applications for 3D printing that is currently being researched is self-replicating robotics. A 3D printer should eventually be developed that will effectively be able to 3D print another version of itself, as well as all kinds of other products and components. (Not an ordinary RepRap, but something more complete and complex.)
