This is a conglameration of things ive read about 3dgun making. Is it all true, I have no idea, I do believe some of it is true and will come to pass.
One article stated that 3d gun making cannot be stopped, it cant be policed and 3d guns in the near future will be everywhere, including assault rifles that are fully automatic. It will make gun control and gun background checks obsolete and put guns in the hands of any person that has the money to buy one.
Another article demonstrates that the plans and guides to make 3d guns are already out there and good to go.
Banning 3d machines would be like banning marijuana or alcohol, wont work, brace yourselves 3d guns will be everywhere and when it happens there will be republicans and democrats alike scrambling to find a solution
