If I had a 3-D printer, I would probably just use it to make "Nation of Jake" action figures.

That pretty much explains why I can't afford a 3-D printer.

Dutch doctors have a more noble application:  REPLACING PEOPLE'S HEADS.

Check out this skull transplant from sunnewsnetwork.ca:

Doctors in the Netherlands have replaced a 22-year-old woman's skull with a plastic one made using a 3D printer.

The Dutch patient had a condition that caused her skull to thicken.

As the skull thickens, it increases pressure on the brain. In this case, it started to affect the woman's motor skills and her vision.

"It is now almost three months later. The patient has her sight back entirely, is symptom-free, is back to work and it is almost impossible to see that she's ever had surgery," Verweij said.

The doctor said using 3D printing will help other patients who need to have all or part of their skulls replaced.
