As far as bullets go, getting smokeless powder will be tricky. You can print the casing in polymer and will be able to print the projectile, but the only powder that you will be able to get no matter what is black powder, which will render an AR15 completely ineffective due to the soot - the primer will be easy enough, but you won't have an effective modern weapon. This is the next problem, but I'd imagine that printable rail guns or some other magnetic accelerator aren't too far behind.
