8 months ago I dropped out of my last year of university for this idea that was ready for the market.
We built PrintToPeer to connect 3D printers to the web to solve the biggest problem in the industry right now, which is the terrible usability and sharing ability of these printers.

If your users have internet connected 3D printers with a common API, imagine what this could do for your games and websites. Your apps can become tangible. Or you can include your early adopters in the physical product development process (A/B testing, hardware updates, etc).
Let us know what you think!
