Bugatti began to print details of titanium hypercars

March 26, 2020 0 By autotimesnews

The Bugatti Corporation has been experimenting with 3D printing elements the year before last and equips them with the Chiron Sport, Divo, La Voiture Noire and Centodieci models. But now the French brand has expanded the scope of the use of additive technologies and for the first time received permission to use visible parts printed from titanium in road cars.

Recently, the French brand is considered the only car company that prints the tips of the exhaust pipes of titanium powder. Moreover, these pads were first certified as a visible structural element of road cars. At Chiron Pur Sport, the dimensions of each such part are as follows: length, width and height – 22, 48 and 13 cm, respectively. Together with the grill and the mounting bracket, the weight of the nozzle is 1.85 kg.

The printing process uses 4 400-watt lasers that sinter 4,200 layers of titanium powder. Thanks to the technology, it becomes possible to create elements having a minimum wall thickness of 0.4 mm and an internal “bionic cellular structure”. And where it is needed, a “lattice structure” is used, in other words, voids fill the struts of a tiny size.

 Moreover, even such a “filigree” element, such as a titanium nozzle, can withstand temperatures of 650 degrees Celsius. A similar result can be achieved thanks to a 2-level external area that provides thermal insulation and at the same time improves cooling.

 Bugatti uses titanium only for printing nozzles on the Chiron Pur Sport and Chiron Super Sport 300+, and for the rest of the cars the heat-resistant alloy Inconel 718 is used. To make tips from inconel, it takes a couple of days, at the same time they are 800 grams lighter than simple ones. After printing, abrasive materials are applied to the surface of the parts and coated with a protective layer of ceramic paint.
