Bugatti Uses 3D Printing To Take Car Building To New Heights

In 2018 the company printed the world's largest titanium component, a brake caliper, and has since followed this up with the world's largest hybrid functional assembly made of 3D-printed titanium and coiled carbon.

"These components are extremely lightweight, robust and durable, and therefore absolutely suitable for use in production vehicles," says Frank Gotzke, Head of New Technologies at Bugatti.

Bugatti has also found a way of including radial compressors on ultra-lightweight magnesium forged wheels. These creations pump air out of the wheel housings which cools the braking system and minimizes lift. Unlike the mono-material technique used on other models, the Bolide components take on a hybrid structure consisting of a central bowl made of 3D-printed titanium with a thickness of 0.48 mm incorporating a 0.7-mm thick carbon plate with smaller inner blades.

The wheels also feature cross-pieces with a width of 0.48 millimeters, weighing only 100 grams that further increases the rigidity of the setup. This all weighs up to a total of just under 400 grams for each 18 ¼-inch turbofan in the rear, and 17 ¼-inch turbofan at the front.
