Polisen oroas av 3D-printade vapen: Hotet är här och nu

A 3D printed firearm is a firearm that is primarily produced with a 3D printer. They can be classified by the type of 3D printers used: plastic (desktop fused filament fabrication), metal (industrial selective laser melting), or both. While plastic ones are usually used as improvised firearms that evade gun control, 3D-printed metal guns are more commonly thought as a way for legitimate gun manufacturers to exceed traditional design limitations.Although it is possible to create fully-plastic guns, such firearms tend to be extremely short-lived. Instead, it is more practical to print a plastic frame and use metal in the action and the barrel. The metal parts can be self-made or bought in the form of a parts kit.A related issue is the production of 3D-printed parts for conventional firearms. Printed high-capacity magazines circumvent limits on assault weapons, sears weaken the control on fully automatic firearms, and pistol braces challenge the limit on short-barreled rifles.
