3D 'human' organs printed to train surgeons

Life-like body parts have been 3D printed to help army surgeons deal with trauma injuries.

Based on CT scans, the organs are fitted into a realistic synthetic "body" and can then be connected to pumps which mimic human breathing and blood flow.

Nottingham Trent University, with the NHS and MoD, used silicone gels to replicate the feel of human tissue.
