A car manufacturer is using 3D printing technology in a bid to thwart theft from vehicles.
As car security systems become increasingly more sophisticated, thieves are targeting car parts instead, including alloy wheels.
Now engineers at Ford are harnessing 3D printing technology to develop next-generation locking wheel nuts.
Together with EOS, a supplier for solutions in additive manufacturing, Ford has created locking nuts with contours based on the driverâs voice.
Like an iris scan or a fingerprint, a personâs voice can be used as a unique biometric identification. Engineers record the driverâs voice for a minimum of one second, saying something like âI drive a Ford Mustangâ, and use software to convert that singular soundwave into a physical, printable pattern. This pattern is then turned into a circle and used as the design for the locking nutâs indentation and key.
âItâs one of the worst experiences for a driver, to find their car up on blocks with all four wheels gone,â said Raphael Koch, Ford Advanced Materials and Processes research engineer.
âSome alloy wheels can cost thousands to replace, but these unique rim nuts will stop thieves in their tracks. Making wheels more secure and offering more product personalisation are further proof that 3D printing is a game-changer for car production.â
