Police investigating the shooting of UnitedHealthcare CEO Brian Thompson on Dec. 4, 2024, have announced that the suspected assailant had used a 3D-printed gun. Several high-profile crimes in recent years have involved this kind of homemade, or partially homemade, weapon.

My best guess is the materials. Last I looked into them they were entirely 3D printed except for a roofing nail to act as the firing pin. The drastic reduction in metal makes them easier to sneak passed metal detectors. Other than that, you seem right on the nose.

I've come across some 3d printed gun content over the last couple weeks (who knows why) and while mostly plastic designs like the liberator exist, most of the development in that area seems to use a lot of metal parts. Generally they're using metal barrels and actions with 3d printed stocks and frames.

The algorithm is foreshadowing /s

This is accurate I'd add there's a distinction to be made between designs that use parts intended as firearms parts (e.g. Glock 19 barrel) and those that use only off the shelf repurposed hardware parts (e.g. ordinary pipe that has been given rifling via electro-chemical machining).
