Switzerland | Zürich-based Urban Alps AG has developed a key technology with a completely new design: the “Stealth Key.” Laser powder bed fusion makes it possible to arrange its security features under narrow strips inside the key. As a result, thieves cannot duplicate it from a smartphone photo or by impressioning. The company uses 3D printing to manufacture the key from a wear-resistant steel alloy in powder form. It uses argon from Messer as a shielding gas.
