Bugatti, a subsidiary of General Motors Corporation (NYSE: GM), has revealed details of a 3D-printed brake calliper, intended to be the largest functional titanium component produced through additive manufacturing.
The Chiron's brakes are said to be the largest of any production vehicle, with eight-piston front callipers and six-piston rear callipers. They are forged from a block of aluminium, utilising bionic design principles to keep weight below five kilograms each. The 3D-printed titanium callipers also appear to use bionic design elements that are particularly challenging to manufacture using traditional methods. The highly optimised design and titanium-aluminium-vanadium alloy are said to achieve a tensile strength of 1,250 newtons per square millimetre, much higher than the Chiron's aluminium callipers despite dropping overall weight to just 2.9 kilograms.
Hamburg-based manufacturing partner, Laser Zentrum Nord, handled the actual printing, creating the calliper using four 400-watt lasers to help fuse layers of titanium alloy powder.
