Just because anyone could doesn't mean that is how criminals operate - your average firearm toting gangster in the UK is not technologically smart. There was a major case a few years back when an armourer got busted for reactivating firearms bought from mainland Europe. He was producing fully automatic Mac-10s and selling them for a few hundred pounds. Unsurprisingly he received life in prison as they had been used in several murders. The UK, despite strict laws on firearm ownership, already has a problem whereby organised crime can acquire firearms - 3D printing is not going to be that much of a game changer.
