IIRC, someone (maybe DAZ) had an arrangement with one of the 3D printing services to allow people to get prints. Presumably, the printers gave a % back to the model creators. I don't know the details or if said arrangement still exists. In theory, 3D prints would be seen as the same as other use, either non-profit or commercial. In fact, I'm pretty sure that some folks will see having a physical model made from their IP as being different for whatever psychological or financial reasons, and want a bigger fee or disallow it entirely. As more individuals acquire the printing rechnology and learn to produce quality models with it, I'm sure we'll see things shake out. It's good to have the conversation now though

I'm not sure how much effect it would have on the larger companies. I'm sure some of the individual content creators haven't really thought about it. Hopefully, there will be some fairly uniform arrangements, otherwise it will become more complicated figuring out what you can use how and when. I'm waiting for 3D  Neural Imaging and whether you can legally beam Vickie directly into someone's brain :-)
