- What is the most interesting thing you have seen done with a 3D printer or 3D printing technology?
It's got to be the prosthetic limbs. I think it's awesome 3D-printers can give people the ability to hold items and even walk at a fraction of the cost of other techniques.

- If you could build your dream 3D printer, what would it include and what would it do? Let your imagination run wild!
It would be able to print in EVERY color and material at a reasonable speed.
