Design students at the Victoria University of Wellington have created a kind of "Steampunk" 3D printer. It's not clear if this is simply a modification of RepRap or Fab@home, but it seems to do the job.
The interesting bit is the main action component: a sewing machine! We suspect this unusual device is a paper cutter, as it "uses waste paper from a bank", and there seems to be a paper hopper visible.
This wouldn't be the only paper-based 3D printer, as we've seen another one from the other side of the planet.
