I'm dubious of 3D printing. I look at the junk on my desk, and think Which of these things could a 3D printer make? Try it yourself! The answer is always None of Them. Mousepad - sorry, neoprene isn't an available material. Headphones - electronics and soft rubber earpieces - nope. Glassed - transparent coated lenses - nope. Book - nope, nope, nope. CD in case - forget it.

I work for the company that is building this 3D printer (Cincinnati Incorporated). I am only a software guy but if anyone has any questions let me know and I'll try to answer them!
