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

It really is hard to choose only one. I would say that one very cool thing is 3d printed organs, which have tremendous possibility, and could help save lifes. The idea that you would be able to print a liver, an ear or a heart is simply too cool to fathom. However, as this really wouldn't have any use for a hobbyis (well, i hope not, but i guess you could write a new take on frankenstein), i am really excited about the idea of printing circuitry.

- If you could build your dream 3D printer, what would it include and what would it do? Let your imagination run wild!
For now, size is somewhat important. Being able to print a fullsize helmet in one piece is insanely cool. Although several extruders, and precision is just as important. I like the idea of being able to print houses with big 3d printers, printing cement, but i'm not sure wether that is quite there yet
