See how the world’s first titan printed caliper passesDecember 21, 2018
In the future, an eight-piston monoblock will be put on a Bugatti Chiron hypercar
Concern Volkswagen Group has published a video from the tests of the world’s first titanium brake calipers, printed on a 3D-printer. The eight-piston monoblock, the mass of which is two kilograms lower than a similar aluminum part, is planned to be installed on the Chiron hypercar.
The caliper is made of titanium powder by the method of layer-by-layer fusion on a 3D printer owned by Laser Zentrum Nord. The printing process takes 45 hours. During this time, four 400-watt lasers sinter 2213 layers of titanium powder into a single design. After that, the caliper is subjected to thermal, chemical and mechanical processing, which allows to ensure its resistance to deformation.
The length of the final part is 41 centimeters, width – 21 centimeters, height – 13.6 centimeters. The weight of the caliper is only 2.9 kilograms, and that of the same aluminum – 4.9 kilograms.
The Hypercar Bugatti Chiron is equipped with a 8.0-liter W16 with four turbines, which gives 1500 horsepower (1600 Nm). The unit is combined with a seven-speed robotized transmission with two clutches and all-wheel drive. From a place up to 100 kilometers per hour, the Chiron accelerates in 2.5 seconds. Maximum speed – 420 kilometers per hour.
