Brendon McNaughton, a 26-year-old artist from Canada, has printed a gold heart using 3D printing technology. McNaughton was inspired by gold miners in Australia and their working conditions there. The workers risk their lives for low wages despite the highly valued goal. In order to publicize this issue, McNaughton designed and created a 3D printed heart of gold. The heart of an anonymous donor was scanned with an MRI. Once printed, it was cast in bronze and then given a layer of gold leaf applied by hand. McNaughton will continue printing hearts on a commission basis of $30,000 with proceeds being donated to cardiac research.
