Prosthetic limbs made by 3D printers

Prosthetics - such as a hand, arm or leg - are needed by an estimated 30 million people worldwide.
But many are forced to do without due to a lack of skilled technicians to make them.
In Uganda, each of its 200 trained prosthetists has an average of 5000 patients waiting for a new limb.
And each amputee could need as many as 20 new limbs in their lifetime, meaning that demand far outstrips supply.
Now a team of Canadians and Ugandans are using a 3D printer to speed up the production process.
