3D printing is incredibly disruptive technology. It has already impacted the debate over guns. Researchers are using it to recreate antique musical instruments.

At 3DPrint.com, they have the story of a Chinese man who lost half of his skull in a fall. 3D printing will give him that half of his skull back.

The 46-year-old was working at his construction job one day when he fall three stories to the ground. The fall left him disfigured, as if he had a large dent in the side of his head.

Surgion [sic] MaoGuo Shu, of Xijing Hospital, who has seen a vast array of head and skull injuries, says that cases like Hu’s are very rare, and finding a solution to fix the damaged skull is very complex and difficult. To try and come up with a solution, the hospital brought in dozens of experts in the field. What they came up with was an idea for a 3D printed titanium mesh which would cover Hu’s brain and help make his skull look normal again. Thankfully for Hu, he won’t have to pay a dime for the surgery, as the hospital is covering the cost, and an American company, Stryker has agreed to pay for the 3D printing and materials used in the printing process.

The titanium printed mesh should return his skull to his normal shape over time. His brain, which was badly damaged in the fall leaving Hu unable to talk and write, might regenerate itself, according to the doctors.
