In relation to file sharing and the future of 3D printing, I think our industry should learn from the painful lessons that the music industry suffered.

First of all DRM did not work. I do not think true DRM protection will work for 3D files either.

What did work was charging a reasonable price for the files. When you charge a low enough price, people would rather buy than steal. When music is $1/song, people would rather pay for it than torrent it. When design files are $2-10 each, people will not really try to pirate them too much.
