GP-printed splints may be a mouse click away

3D printing is supposedly the future of medicine.
3D printers craft raw materials such as resin-like substances into an object by building it layer upon layer. It’s also known as additive manufacturing.
The technique is meant to make it relatively cheap to create patient-specific prostheses, hip replacements and even experimental silicon hearts.
In the US, 3D printing is controversial because people have started printing parts of guns, with no serial numbers.
