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

Used by Nasa, Re-create broken body parts (bones) etc & Most intersting for me is 3D Printed Houses..

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

Atleast in india it takes months to build a regular house by a traditional builder with lots of manual Labour and still not everyone cannot afford to !,
3D Printing house can not only bring that change But help poor segment of the people to own a shelter at 1/10th of the cost ! May not be a building but a shelter for sure.
