Bugatti is developing the world’s first 3D-printed brake calipers for introduction on its Chiron hypercar later this year – and the firm has called this the first of several significant production breakthroughs.
Each titanium caliper is created from a monobloc of titanium made using 400W lasers. The part uses 2213 layers of titanium powder, which is heated to 700deg C during a 45-hour-long production process.
Bugatti claims the caliper – which is the longest car caliper in production, at 41cm long – weighs 2.9kg, 2kg less than the aluminium caliper offered on the Chiron. Despite the weight loss, it’s said to be tougher than the aluminium part.
The technology used to create the new caliper stems from the motorsport and aviation industries. Bugatti said the caliper is the first of several parts it can now make thanks to the introduction of this 3D printing system.
Frank Götzke, Bugatti’s head of new technologies, has also hinted that the tech could be used elsewhere in the Volkswagen Group. He said: “In 3D-printing development, Bugatti is the leader in the group. Everyone can, and should, benefit from our projects. This is also part of Bugatti’s role as the group laboratory for high-tech applications.”
