In this video, we meet Kevin Vaughan, a 30-year-old Marine Corps veteran and amputee as he learns to use his amphibious water prosthetic, ‘The Fin’, a 3D-printed leg engineered for swimming.

After an explosion left him severely injured during a tour of duty in Afghanistan in 2011, Kevin was faced with a choice – keep his biological leg with little chance of normal mobility, or choose to lose it, and then enjoy acceptable mobility again, using a prosthesis.

Here, we see how Kevin transformed his life by embracing the second option, relying on an array of 3D-printed prosthetic legs to help him carry out specific tasks and activities. One of these, ‘the Fin’ allows him to reclaim an old pleasure – swimming.
