Wow! This is quite the contest. Thanks for putting it all together.

- What is the most interesting thing you have seen done with a 3D printer or 3D printing technology?
Most interesting project is a toss up for me. There's the "tug at the heartstrings" story of the group project leading up to a robotic hand: http://www.dezeen.com/2013/05/29/3d-...thout-fingers/
And then the items that defy injection molding such as this Gyrornament: http://www.thingiverse.com/thing:225494
- If you could build your dream 3D printer, what would it include and what would it do? Let your imagination run wild!
Layer process 3-D printing via filament, SLS, CnC and powder bed. Why not have them all at once as long as I'm dreaming? Also, integrated scanning would be nice.
