3D printing procedure is complex and expensive. It is because of this that it is widely utilized in the aerospace sector. Bugatti, the best maker of hyper sports vehicle utilized pieces with additive manufacturing technology in its Chiron Super Sport 300+ and Chiron Pur Sport.

President of Bugatti, Stephan Winkelmann stated that Bugatti is not only about French-style richness and excellent cars, but is as well a brand that is for innovative technology. Technical discovery is a big part of the brand narrative as its popular 8.0 liter 16-cylinder motor with 1,500 PS. This technical discovery extends to the usage of pieces made of titanium or a unique alloy that are made by 3D printing.

Therefore, Bugatti is keeping it true to its well-established custom here as the firm’s founder Ettore Bugatti himself is popular for having created unique cars utilizing cutting-edge technologies. His discoveries comprise of lightweight aluminum rollers and a hollow front axis.

Bugatti is the exclusive automotive firm that utilizes additive manufacturing to style tailpipe trim cases from titanium for its unique hyper sports vehicle. Also, this cover is the premier visible component that is 3D-printed in metal to be formally certified for application in a roadworthy vehicle. The trim covering of the Chiron Pur Sport’s has measurements of 22 centimeters length, 13 centimeters height, and 48 centimeters breadth but weighs just 1.85 kg. 

The weight includes its bracket and grille. This weight of the trim cover is 1.2 kg less than the Chiron cover weight. The trim covering piece is created simultaneously through the use of 4 400-watt lasers to print titanium with the thickness of the wall at the thinnest level being only 0.4 millimeters.

Around 4,200 layers of metal powder are stacked on one another and are firmly fused together as pieces of the procedure.  The Head of Body Development at Bugatti, Nils Weimann, mentioned that wherever practicable, the trim covering for the Chiron Pur Sport was created with one layer to more lessen the load. 

The thinness of the material even in multi-layer places was created by its special lattice composition where the cavity is filled with several filigree struts.

The wall offers steady support for each other in the construction procedure, only minimal material requires to be utilized as the walls’ surface rigidity has been raised with the usage of as bionic honeycomb construction in the one-layer field. Even bigger parts thus have a high level of surface inflexibility.

 The filigree covering can endure temperatures that are over 650 degrees Celsius as the external wall is dual-layered for thermic insulation. Therefore, the cover shields surrounding pieces from unnecessary heat distribution under full engine weight. But at the same period, the piece is chilled by the fresh air just about the cover.

This isn’t the initial time the firm has created pieces by the use of additive manufacturing. Bugatti’s engineering crew has been creating this unique trim sheet for the Chiron Sport and Divo sine 2018. Different models where the trim covering can be noticed are the 2019 editions of “La Voiture Noire”, the ultimate Grand Tourisme, and the Centodieci, a fresh take on the EB110.
