What is the most interesting thing you have seen done with a 3D printer or 3D printing technology?
The most interesting thing I have seen done with a 3D printer is printed medical models of human anatomy. This is amazing as it helps doctors learn about human anatomy with cheaper printed anatomy models without having to use real human cadavers. It is also helpful for doctors who can use it for study before actually going in for the surgery.

If you could build your dream 3D printer, what would it include and what would it do? Let your imagination run wild!
If I could build my own dream 3D printer, it would include a function to replicate exact human tissues and organs so that doctors can use it for immediate replacement for patients who need it. It would help all especially the less well of in view of the escalating cost of medical fees and operations.
