So close, and yet so far from a real hypothetical.
The real question is can 3D printers be used to get around patents. So lets say you invent a device to triple gas mileage, is it freedom of speech for me to distribute a CAD file to make it, and thus cutting you out of any profits.
To get a patent, you must make your invention public for anyone to copy. But copying things used to be complex enough that only legal factories could do it. We are entering an age when anyone might be able to copy a manufacturing process. It might be as easy as copying a music file has become.
