Factual error: Sherman prints a gun through the hospital's 3D printer. We see the gun, the cylinder, and 6 bullets. But if bullets are printed too, they still would need to contain the gunpowder, and the 3D printer construct shown there looks made out of a single kind of material, plain looking, surely not the product of a wonder machine that'd be able to recreate the complex chemistry required to make working bullets it was not even designed to do - in fact they look like suppositories, with no division at all between primer, casing, etc.
