That won't make it through a metal detector
Neither will 99% of 3D printed guns. Most 3D printed guns use metal parts, and ammo will likely be detected as well. Only single shot, entirely 3D printed guns with plastic ammo have any chance.
100% of 3D printed guns.
Barrels and chambers are quite difficult to 3D print. But springs strong enough to set off primers, cartridge casings, and bullets must be made of metal. You can get clever with all of the above, but a plastic bullet would be laughably ineffective and even if you're going to go with electrical rather than mechanical ignition to eliminate the springs you're going to need metal batteries, metal wires, metal switches...
It is functionally impossible to make an all-plastic firearm. You'd be better off making a Jörg Sprave style crossbow or something.
The Liberator is a completely 3D printed single-shot pistol that can shoot 9mm.
The Washbearis a completely 3D printed revolver.
3D printed ammo is currently in development.
They aren't very practical, but can likely go through metal detectors.
Except for the firing pins. And the ammo. So it's likely that they actually can't, unless the detectors at the facility in question are so detuned that they'd also allow through razors and small pocketknives.
Printed bullets would be like firing frozen paintballs at people. Injurious, yes. Deadly, most likely not.
