Urbanalps' 3d-printed stealth key is almost impossible to forge
Swiss company UrbanAlps has devised a method for 3D-printing keys to make them almost unforgeable, because their teeth are hidden from view.
The Stealth Key was designed by UrbanAlps as a safer alternative to regular keys, which can be easily scanned and copied.
In what the company says is a world first, the keys are 3D-printed from titanium. Because they use a form of additive manufacturing, the keys are effectively formed from the inside out – meaning their teeth can be hidden under a pair of narrow ledges.
However, they work like most contemporary keys, fitting inside a cylinder lock to turn the mechanism.
