- Researchers analyzed how intellectual property is shared on Thingiverse, the largest online 3D printing design repository, by examining license choices and interactions among users and between users and MakerBot, the owner of Thingiverse. They found that while most public designs use open licenses, 42% of all designs are kept private, and MakerBot has moved away from open practices around its own hardware and software designs. The analysis reveals inconsistencies between the rhetoric of open sharing promoted by Thingiverse and the realities of both user and company behaviors regarding intellectual property.
