People have been making 3D-printed guns at home for nearly a decade, but in the last few years, 3D printed technology, blueprints of weapons, and materials have rapidly evolved that allows anyone to print AR-15s, AKMs, semi-automatic pistols, and others with no serial number, no registration, no background check.
These weapons are also known as "ghost weapons" due to their untraceable nature. Criminals are embracing ghost guns and even creating manufacturing facilities.
Reuters reports Spanish police busted a 3D-printed weapons factory that produced illegal and untraceable firearms in the country.
Spanish police raided the illegal weapons workshop in Santa Cruz de Tenerife in Spain's Canary Islands and arrested two people in possession of weapons and explosives.
Spain's National Police said police found 3D-printing equipment that could print lowers for weapons. They also found machinery that could manufacture gun barrels in under two minutes, leading authorities to believe the rate of weapons produced at this factory could be staggering.
