I love 3D printing and I am thinking of selling some of my prints but most of my print models are downloaded from a website. 3D models came with Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0) and some are Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0) .

If I edited for example this 3D model of a car, let say I put a new headlights or put a new spoiler and skirts, which of these two CC license I violate? And if I edited a model and sell them, did I violate these rules?

Car model

  • Selling the models for profit appears to violate the non commercial clause of both licenses. – Brandin Sep 24 '18 at 5:11
  • @Brandin thank you very much for the quick reply! The CC applies to the blueprint, so other person creates the blue print and I download their work, do modifications and print the models. Still the CC rules applies to the printed model? Sorry, as I am not aware of these laws. Thanks again man! – vnpnlz Sep 24 '18 at 5:14
  • After you modify the models, that is a derivative work so to sell your modified model you need a license from the copyright holder. But if you take a model and then produce a physical product from that model, I'm not sure how the resulting physical product would be protected. – Brandin Sep 24 '18 at 5:25

Both of them

The physical manifestation of a 3D print model is a derivative work and so you must follow the licence. The licences are "non-commercial" - selling stuff as a business is squarely commercial.

  • So if the 3D print model license falls in Attribution 3.0 Unported (CC BY 3.0) means I can sell them? – vnpnlz Sep 24 '18 at 6:50
