I would argue instead that DRM is the last thing we want to infect the 3D printing industry. While it is important for intellectual property holders to protect themselves from large scale mass reproduction of their designs, DRM does more to hurt the end consumer - and indeed the industry DRM attempts to protect - than it does to protect the revenue of property holders.
