China3D printingNet news on April 14,3D printingIt has proven time and time again that it is the leading technology for manufacturing short-term special parts, so it has been widely used in aerospace. Corresponding with the development trend in the aerospace field is the use of additive manufacturing (AM) in luxury and self-driving cars.Bugatti (Bugatti) once again deployed the technology to Chiron Pur Sport and Chiron Super Sport 300+3D printingThe titanium exhaust pipe is decorated with a cover.

The size of the decorative cover is about 22 cm long, 48 cm wide, and 13 cm high. It weighs only 1.85 kg, including the grill and stand.The parts are processed by using laser powder bed fusion technology3D printing, Bugatti was able to reduce the weight of parts by 1.2 kg. Design optimization includes lattice structure and filigree pillars. At the thinnest part of the part, the wall thickness is only 0.4 mm, and only a layer of printing powder is used.
By using an outer wall that provides a double layer of insulation, the parts can withstand temperatures exceeding 650 degrees Celsius. Therefore, when the part itself is cooled from the surrounding fresh air, the part can protect the surrounding components from the heat dissipation of the engine.

Bugatti first publicly began to test the end parts of AM in 2018.It goes first3D printingTitanium alloy brake caliper, which is the largest ever manufactured3D printingTitanium alloy parts.Then, the company started using aluminum3D printing, Making it 40% lighter than the traditional version, while still maintaining an operating temperature of up to 1100 degrees Celsius. According to reports, the company had previously manufactured internal parts and dashboards for Veyron, but it has never been confirmed.
Since 2018, Bugatti has been using AM to produce interior covers for its Chiron Sport and Divo, and uses nickel-chromium alloy Inconel718. Compared with the traditional outer cover, its weight is only 2.2 kg, and the weight is reduced by 800 grams. The interior cover of the 2018 model covers four exhaust pipes to minimize heat accumulation in the exhaust system.
For 2018paymentFor the decorative cover, Bugatti relies on computer tomography technology to check the defects of the parts during printing. Optical inspection is used for new exhaust pipe covers, which are thin enough to detect air inclusions from the outside.
In order to complete the Chiron Pur Sport and Chiron Super Sport 300+3D printingThe exhaust pipe cover is sandblasted with corundum before the high temperature black ceramic coating. This allows the components to maintain a matt effect, while also providing better protection.
As mentioned earlier, this is just the latest news that AM is widely used in luxury and motorsport production.From McLaren to Ferrari, many racing car manufacturers are now using this technology, from the production of jigs, fixtures and prototypes to3D printingTerminal parts. Supercar manufacturers, including Lamborghini (Lambourghini), in addition to prototype manufacturing and manufacturing aids, also use AM for terminal parts.
The latest announcement is partly different from the previous work in that the exhaust caps of the Chiron Pur Sport are the first batch to be approved for road use.3D printingMetal parts, but the price of Chiron Pur Sport is about 3.5 million U.S. dollars, while the price of Super Sport 300+ is close to 4 million U.S. dollars.
China3D printingOnline reviews:IWe have recently learned that using these new technologies to create these high-performance parts can be turned to more critical tasks at any time.ŠKODA, the Czech subsidiary of Volkswagen Group, is currently using its original3D printingRespirator masks to respond to the COVID-19 medical supply crisis in the Czech Republic. Because we may enter an era of unprecedented supply chain disruptions caused by an unprecedented climate crisis (including further epidemics), it may be necessary for companies involved in less important industries to shift their focus to more urgent commodities.
Currently, this means the use of medical supplies such as respirators, masks, nasal swabs and ventilators. In the future, this may mean an emergency response to the collapse of infrastructure due to extreme weather events or even the mass production of renewable energy systems.
