Lets say in 10 years, 3D printing technology become so advanced, almost anything can be perfectly replicated. So I find some leaked car 3d file, I download it, I print the car. What current laws would I be violating? Civil or criminal? And what future laws can you anticipate?
Use it on private property like a farm, very little laws on that.
Sure, but then I doubt anyone will be coming after you for patents
