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

I've seen some really promising 3d-printed widgets mashuped with RaspberryPis. I'm very excited about the possibility of printable circuitry.

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

I'd really like to see a commercial-grade 3D scanner/printer with multiple extruders, including a conductive solder extruder and CNC routing. Imagine being able to produce carved wood bases and 3D-printed electronics all in one step with a single, super-powerful machine.
