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

Well, other than the small model of the Battle School I had printed to my designs on a Z-Corp printer, and the MC Escher "Cube" (labyrinth) that a friuend printed up, running to the maximum dimensions possible on that Z-Corp printer, I would have to say prosthetics. Especially that aretifial hand that's been making the rounds on the news media these days!

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

If a 3D printer could print something on the order of a MOTOR, I'd say we were almost there.

If it could print in a range of materials, including 50 ksi or better steels, I'd be pretty impressed!

I'm sure at some point in the future, there will be 3D printer needles (stylii) that will be able to precipitate out ANY material you wanted...ah, to dream!
