China3D printingNet January 28th, luxury car manufacturer Bugatti (Bugatti) announced the use of additive manufacturing in its new concept supercar Bugatti Bolide.
The design details of the car were led by Henrik Hoppe, a doctoral student in the company’s new technology department.As early as 2017, Hoppe made the Bugatti Chiron’s3D printingThe calculation method of the brake caliper wrote a master’s thesis, and compared with the original production parts, the weight of the brake caliper was reduced by 43%.
Since then, industrial engineers have developed a new system designed to determine the metal in Bugatti’s latest performance vehicles3D printingCommercial and technical feasibility. The Bolide concept first debuted in October 2020, with an 8.0-liter W16 engine, weighs only 1240kg, and has a top speed of more than 500 km/h.

When designing Bolide, Hoppe planned every step of vehicle manufacturing and performed all necessary calculations to ensure that it is indeed feasible.Vehicle3D printingComponents are inspired by bone structure, and their main features are thin walls (some thicknesses less than 0.4mm), hollow interior and fine branches.According to China3D printingWang understands that the choice of bionic design has excellent rigidity, while greatly reducing the weight of the parts.
Hope added: “Through a process called selective laser melting, new hollow and ultra-complex parts that harden from the inside can be produced. These parts are very lightweight but very strong and strong. We will continue to reduce the weight of the car. At the same time increase its innovative functions in every possible field.”

Weighs only 100 grams3D printingPutter
At Bolide3D printingAmong the components, the putter weighing only 100 grams is very prominent. The pressure-loaded titanium alloy connecting rod is located in the chassis area. Although the rod is heavy, its hollow structure has an internal supporting arch structure, so depending on the operating conditions, the rod can transmit up to 3.5 tons of force.
The putter is also the first example in Bugatti’s history to change the thickness of a thin-walled hollow rod within its length. The part thickens toward the center and then thinner again toward the limbs, which means it is optimized for local stress and weight at the same time. The company has even registered a patent application for the structure.
Optimized weight-to-strength ratio
With an incredible weight-to-strength ratio3D printingOther examples of components include titanium mounting brackets for Bolide’s front wings. Although it weighs only 600 grams, the mounting bracket can withstand up to 800 kg of pneumatic downward pressure, and the internal hollow wall thickness is 0.7 mm.
Looking at the car’s exhaust pipe decorative cover, this is a made of titanium and ceramic3D printingHybrid components, Bugatti managed to reduce its weight by about 50% compared to the already optimized mass production model. The weight is now less than 750 grams, and the wall thickness of the part is 0.5 mm.
The ceramic element of the decorative cover is built in the titanium metal shell, which has excellent insulation performance. Bugatti made design choices to protect the carbon skin from the effects of high-temperature exhaust gas. The built-in Venturi nozzle also contributes to the insulation function, which creates a layer of cold air around the hot exhaust gas. The entire assembly is sufficiently innovative, so a patent application has also been submitted.

Among the major automakers, Bugatti undoubtedly occupies a considerable share of additive manufacturing production. In addition to Chiron’s brake calipers, Bugatti has previously cooperated with Scalmalloy manufacturer APWORKS to provide Chiron Pur Sport 3D printingTitanium tailpipe.Bugatti is also with3D printingMachine OEM SLM solution cooperation, also had3D printingThere are spoilers, motor brackets, cylinder head covers, tail fin lights, and even the front axle differential.
