New Bugatti: titanium exhaust trims from the 3D printer
Apworks, a provider of 3D printing services and products, is equipping the new Bugatti Chiron Pur Sport with an extremely lightweight and high-temperature resistant exhaust cover.
It is made of titanium and is produced by Apworks using additive manufacturing. This manufacturing method enables a component with extremely thin walls and thus helps to save weight. Additive manufacturing is the most suitable manufacturing method for this, as it allows a high degree of design freedom that no other manufacturing method can achieve.
The exhaust trim is part of the extraordinary rear design of the Chiron Pur Sport. Newly tuned aerodynamics ensure more downforce, less weight and more agility. "With a reduction in weight of 50 kg, a simultaneous increase in downforce and an uncompromisingly sporty suspension, the car offers incredible grip, sensational acceleration values and extremely precise handling. It is the most uncompromising and at the same time most agile Bugatti of modern times to date," says Stephan Winkelmann, President of Bugatti.
Low weight and new aerodynamics
The low weight of the trim contributes to the newly tuned aerodynamics of the hyper sports car, which is designed for driving on extremely winding roads. "Agility was particularly important to us with the Chiron Pur Sport. We achieve more downforce on the rear axle, and the large front splitter, the air intakes, the wheel arch ventilation with optimized air outlets and a reduced ride height balance this out perfectly," says Frank Heyl, Head of Exterior Design and Deputy Chief Designer at Bugatti.
The exhaust cover is also resistant to high temperatures due to its production from titanium, as the material combines high strength and good heat resistance. This is an example of an optimized high-performance component made possible by additive manufacturing while meeting the highest quality standards and road approval requirements. "We are proud to be part of this impressive new sports car from Bugatti. It is the first 3D-printed metallic visible component to receive road approval. We were only able to realize this exhaust cover by pushing additive manufacturing technology to its limits. Minimal wall thicknesses of less than 0.5 mm make the extremely lightweight design possible," says Joachim Zettler, Managing Director of Apworks.
