Even though anyone willing to shell out $850,000 on a 3D metal printer can now produce fully functioning guns in the legal comfort of their own home, it’s not time to cry foul on the emerging technology. A lot of other people are creating some amazingly innovative and non-lethal things that won’t leave you wondering which 3D-printed guns can and can’t be detected by metal detectors.
Engineers, for example, have long enjoyed using 3D printers to pop out quick prototypes made of thin plastic filament, layered on top of itself to create solid objects. Over the years, the machines have become more advanced, now capable of providing us with other, more widely useful applications, from car parts to body parts. And printers are becoming cheaper, too, meaning it’s becoming a lot easier for people to buy them for personal use.
