- What is the most interesting thing you have seen done with a 3D printer or 3D printing technology?
Creating prosthetic devices for children is the most interesting (and moving) thing I've seen in the 3D printing technolgy.

- If you could build your dream 3D printer, what would it include and what would it do? Let your imagination run wild!
A print head that accepts white filament and uses standard inkjet cartridges Red, Blue, Yellow and Black to create full color prints would be great.
A print head that accepts an aluminum based filament to create metal prints would also be good step in the direction of metal printing.
