We reveal 5 medical marvels introduced by 3D-printing
The 3D technique is now being widely used in healthcare to help make everything from new hands to replacement skulls. The 3D technology involves using a machine similar to an ordinary printer. But the machines 'print' layer upon layer of materials such as plastic, metal or wax to form the finished article. They are even being used to print living cells. The objects are relatively cheap to produce and, because they're based on data from scans, can be very precise.

3D technology has been used to improve healthcare in many ways such as Printing drugs at doses tailored to individuals, a life-size model of the kidney to replicate a patient's kidney stone, a plastic skull that retains the patient's brain functions, living cells, half-pelvis and more..
