If this video had come out in April I would have thought it was a prank. I've seen 3d printers before but nothing with this much precision. What is most impressive is the fact that this thing can somehow "print" internal moving parts. This printer may not be directly related to photography but it's so versatile, it could be related to anything. I recently lost my lens hood for my 24-70mm lens. It would be nice to print another one and save $30. Maybe my kids will have that luxury.
