Brakes are arguably the most important part of a car. Bugatti, a company that makes big and fast toys for very wealthy people, is testing out its 3D-printed brake caliper for production—and it’s actually wild to watch.
Last year, Bugatti announced that it had successfully 3D printed a brake caliper and had plans to put them on the Chiron as soon as they were production-ready. The calipers are lighter, stronger and take about 45 hours to print, in which 2,213 layers of titanium dust are melted on top of each other to create the shape. And then:
Once complete, the full caliper housing is heat-treated in an oven heated up to 700 degrees Celsius (nearly 1,300 degrees F)... the caliper is then taken through a few long processes to ensure a smooth and bright finish.

Comfortable for anyone
Nnjoy the water but don’t want to deal with the hassle of traditional kayaks? This is portable, lightweight, and easy to store when not in use.
If that all sounds insanely expensive, it’s probably because it is.
Yesterday, Bugatti released a video of its engineers testing the caliper. I’ve seen brake rotors light up under hard use plenty of times before, but it was something else to see a naked rotor do it.
The sensors show that Bugatti was running the rotor at well over 200 mph and after braking, the rotor temperature shot up over 1,600 degrees Fahrenheit.
Bugatti says this is an eight-piston, monoblock caliper and can apparently stop the Chiron from 100 mph in just 2.5 seconds. Damn.
Take a look for yourself, and don’t get discouraged by the melodramatic beginning. The action stars about 30 seconds in.
