- What is the most interesting thing you have seen done with a 3D printer or 3D printing technology?

Seeing a trachea printed for a 3 year old girl so she could breathe and talk again.

- If you could build your dream 3D printer, what would it include and what would it do? Let your imagination run wild!

I'm a RC sailor, I would love to see a printer do full sized racing hulls, 3-4m in length.
