The ReMotion Knee is a low cost prosthetic knee joint project that was started in 2008 as a graduate biomedical engineering class assignment. The class collaborated with the JaipurFoot Organization, India’s largest provider of low cost prosthetics, and later teamed up with San Francisco based designer Vinesh Narayan and D-Rev, a non-profit product development company. Narayan has been continuing the project and recently won Proto Labs Cool Idea! Award. Proto Labs is providing D-Rev with injection molded parts to fulfill its next round of testing.

We interviewed Samuel Hamner, design engineer with the project, about how rapid injection molding help move the project forward.
