Except, as brought up elsewhere in the thread - the present state of 3D printing (and the state in the foreseeable future) also require substantial personal skill to print a weapon. The prospect of an unskilled individual loading a file in a program, hitting "print", and retrieving a usable gun from the other end, is not at all realistic. I still don't see what distinguishes this from good old gunsmithing laws/issues.
