On 3d printing and Creative Commons NC = non commercial

My designs are usually CC-BY-NC or CC-BY-NC-SA .
Here is my understanding of this.
Please comment if your interpretation differs from this.
If you know of any interpretation or discussion about NC and SA regarding designs for 3d printing, I'd be glad to list them here!

Short version: You can make and change them but not sell them.
Because if anyone is selling my design or physical parts I designed, that should be me.


Any derived design gives attribution that it is based on this one.
Nobody else is free to call him/herself creator of this design.


"copies or adaptations of the work to be released under the same or similar licence as the original"
Printed objects (in my understanding) are not copies or adaptations of the design. They are the design "in all media and formats".
The medium here is a physical object. It is therefore not a derived design but just another representation of the same design.
Changed designs however need to have the exact same license (or one that CC has publicly declared to be compatible).

Even without the SA part derived designs are still Non-Commercial.


You may not sell the design and you may also not sell 3d printed or CNC milled or otherwise manufactured physical representations of the design for money.
Legalese: "in any manner that is primarily intended for or directed toward commercial advantage or private monetary compensation"

You are free to make physical copies for yourself or friends.
You are not free to sell them in a shop.
You are free sell the service or 3d printing designs in general and accept this design as given by your client to be made.
You are not free to advertise this design to be made or sell physical copies to anyone but that one client who ordered you to make it. (e.g. that client using your website to open a virtual shop.)
You are free to give one to a friend for free.
You are not free to give one or many away as advertisement.
You are free to sell a personally used machine that just contains a replacement or improvement I designed.
You are not free to sell (a) new machine(s) and advertise that it contains my improvement.


Neil Underwood hat gesagt…

Under this Licence do you mind if I where to charge someone to cover the plastic if I printed a foldarap for them? What if I wanted to sell RP parts for this machine on Ebay?

Marcus Wolschon hat gesagt…

I'm not familar with "foldarap" or it's license(s).
You can of cause charge for the service of making things.
If it's published only with an NC -license you can't sell parts of the design on eBay.
