3d Printing.. The answer to a magazine ban?

I've been looking at some worse case scenarios with regard to a gun ban and one keeps sticking out as being a game changer.

3d printing.

For the price of a high end AR-15, I can get a printer and at the very least replicate certain parts.  Other parts can be machined in any decent machine workshop.

As a matter of fact that's how many AR-15 manufacturers got started.  They simply had a decent machine shop and fabricated parts.

Now is not the time to look at wild cat ideas but the implications are clear.  A large portion of the US public is about to be declared criminals and you can bet money that many will find work arounds to those ILLEGAL proposed laws.
