Bugatti to Print Titanium Exhaust Pipes on a 3D Printer

Bugatti has been experimenting with 3D-printed titanium hypercar parts for several years.

Manufacturing these parts is quite time-consuming, because titanium is not the softest and most stable metal. However, the company does not intend to abandon this technology: Bugatti’s printed parts have already been installed in the Chiron Pur Sport1, Super Sport 300+, Divo, La Voiture Noire and Centodieci.

While the company previously used this technology to manufacture components, it now has permission to produce external parts from printed titanium, in particular exhaust muffler nozzles. The first model to receive printed muffler nozzles will be the Chiron Pur Sport. Together with the grid and mounting, the printed part weighs 1.85 kg, which is 1.2 kilograms less than the weight of the standard nozzle.

Four simultaneously operating 400-watt lasers are used to make these titanium muffler nozzles. The thickness of titanium at the thinnest point is only 0.4 mm. Besides, the technology allows making the structure of the part lattice, thereby reducing the amount of material used. The nozzle made in this way is very durable and can withstand temperatures up to 650°C. This is made possible by a double-layered exterior that provides thermal insulation and also improves cooling.
