Prototype bionic eye created with custom 3D printer
When he was an assistant professor at Princeton University, Michael McAlpine led the development of a 3D-printed bionic ear. Now an associate professor at the University of Minnesota, he has gone on to 3D-print a rudimentary bionic eye – and it could eventually lead to versions capable of replacing the real thing.

Eventually might become more useful than the real thing, zoom ability, information overlay, etc
Began with a hemispherical glass dome. Using a custom-built 3D printer, they then added stripes of an ink containing silver particles – the ink successfully dried in place, as opposed to running down the inside of the dome and pooling at the bottom. Finally, over top of that ink base, a printed layer of a semiconducting polymer was added. The result was an array of 3D-printed photodiodes, which are capable of converting light into an electrical current with an efficiency of 25 percent.
So it’s essentially just a retina-shaped camera. No cells or optical processing is involved in this version.
It would be interesting to see how it interfaces with real cells and nerves.
