In recent years, the event of 3D-printing, by which a printer can be used to construct a stable object, has the potential to vastly complicate attempts to regulate firearms. The earliest 3D-printed guns were crude single-shot devices. But as Slate author Ari Schneider reported in 2021, the technology has come a long way in a short while, and it’s now possible to print semi-computerized rifles and pistols that don’t have serial numbers or registrations, bypassing background checks. Just lately, for example, plans had been released for a «a hundred % homemade» semi-computerized rifle that’s durable sufficient to shoot 1000’s of 9 mm rounds. A lot of the rifle could be 3D-printed, whereas the rest might be fabricated from components available in hardware stores.
