I also think the law is bad.

I do want to point out that if you want to make durable parts with a 3D printer, the easiest thing to do would be to create the part with the printer, then use it to form a mold for casting the part out of metal. Then case harden. That's the cheap and fairly easy way. I just want to point that out because I think that use case of 3D printers gets overlooked. Or you buy a fairly expensive lathe/mill.
