The Guardian recently reported on Micropasts, a British Museum crowdsourcing project that combines cultural heritage work and 3D printing (http://www.theguardian.com/science/2014/aug/18/volunteers-british-museum-crowdsourcing-archeology). The project uses crowdsourcing for transcriptions of object records and photogrammetric development of 3D object models. This project was supported by Joseph through volunteer participation based on his interest in digital humanities and his work with 3D printing at the Digital Commons of the DC Public Library in Washington D.C.
Be sure to check out Micropasts and their neat crowdsourcing interfaces.
Also, be sure to learn about the Digital Commons and their 3D printing services.
