Extremely lightweight, highly temperature-resistant, additively manufactured, road homologated
This is the "identity" label of the 3D printed titanium exhaust tailpipe in the new Bugatti Chiron Pur Sport.
Optimized, high-performance component additive manufacturing
Bugatti released Chiron Pur Spor in early March. Chiron Pur Sport reduces the weight of 50 kg, while increasing the "down force", and equipped with uncompromising sports chassis and suspension device, with a strong grip, sensational acceleration and extraordinary precision control. Chiron Pur Sport is designed for driving on extremely curved roads, with more emphasis on agility and dynamic cornering.
In terms of appearance, Pur Sport uses an aerodynamically optimized front face design. The vents are now widened, the bottom of the horseshoe-shaped panel is enlarged and a new front throat design is used, all of which are made of carbon fiber materials. At the rear, the new car is equipped with a 1.9-meter-wide tail, and is equipped with a heat-resistant 3D printed titanium alloy tailpipe.
The Bugatti Chiron Pur Sport will start production in the second half of 2020. The final production will be limited to 16 units, excluding VAT. The official price is 3.2 million euros (about 24.88 million yuan).
The 3D printed titanium tailpipes used in the Bugatti Chiron Pure Sport are manufactured by Airbus subsidiary APWORKS. According to APWORKS, this is the first metal 3D printed component to receive road certification, and it is a typical application of additive manufacturing technology to optimize high-performance parts.
Titanium exhaust tailpipes have a minimum wall thickness of less than 0.5mm and are extremely lightweight. According to APWORKS, additive manufacturing-3D printing technology can achieve very complex designs, making it the best way to manufacture this exhaust tail pipe. Titanium alloy materials have both high strength and good heat resistance.
The 3D printed titanium exhaust tailpipe is part of Chiron Pur Sport ’s extraordinary rear design. Its new aerodynamic configuration produces greater downforce, while the lighter weight helps increase the vehicle ’s flexibility.
Bugatti has become the leader in accelerating the application of technology in the automotive industry through metal 3D printing.
Bugatti has developed 3D printed functional components-brake calipers, spoiler brackets, motor brackets and front axle differentials. Bugatti uses selective laser melting metal 3D printing technology to mass-produce the motor bracket, which has been installed in the new Chiron series vehicles.
It is worth noting that Bugatti does not use 3D printing technology to manufacture traditionally designed parts, but explores and explores the value of 3D printing technology in product remodeling. Taking the 3D printed motor bracket as an example, Bugatti redesigned the small motor bracket for the Chiron super sports car. This bracket integrates a cooling water circuit, and this functionally integrated complex component can only be achieved through 3D printing-additive manufacturing technology. Functionally, this 3D printed small motor bracket can act as a heat shield, significantly reducing the heat transferred by the motor.
