The automotive industry has always been a key application area for 3D printing technology. At present, it has surpassed the aerospace industry and has become the first industry with 3D printing vertical applications. 3D printing technology enables large -scale car companies to reduce costs, time and weight when producing complex parts. In addition, 3D printing also brings greater design freedom, which can design some complicated structures. In view of the significant growth of 3D printing in the automotive industry, it is expected that by 2028, the output value of 3D printing in the automotive industry will reach $ 12.4 billion.

各大汽车品牌是如何应用3D打印技术的(上)?

The following is the summary of the application of 3D printing technology from major foreign car brands.

Audi

Audi introduced the printing system of 3D printing company Stratasys a few years ago to speed up car design, that is, in the R & D stage, 3D printed the prototype of various new design parts for testing and evaluation. In addition, Audi also incorporates 3D printers into its production line for the production of wheel hoods, grilles, door handles, and rear lights.

Bentley

各大汽车品牌是如何应用3D打印技术的(上)?

Bentley has been expanding the application of 3D printing on cars. At present, they have invested more than 21 million yuan in 3D printing technology. In 2021, they printed more than 15,000 terminal applications in 3D, which not only saved the design and manufacturing time, but also reduced waste. In addition, because Bentley’s annual output is small, and the number of some parts is relatively small, using 3D printing has economic benefits. In addition to its own benefit, Bentley also enriches customized services based on 3D printing technology, allowing customers to customize more components.

BMW

BMW, has been using 3D printing technology for more than 25 years, is one of the earliest car manufacturers to integrate this technology. In June 2020, they also opened their own 3D printing centers, with more than 80 employees of more than 50 industrial 3D printers. When producing a sports car i8 Roadster, BMW also used a large number of 3D printed parts, which not only achieved lightweight, but also improved its intensity. Components such as hood brackets have become lighter and stronger.

Bugatti

In order to create the lightest, fastest, and most aggressive supercar in order to create the lightest, fastest, and most aggressive supercar, this French car manufacturer has also launched 3D printing technology so far. Their latest supercar Bugatti Bolide uses some 3D printed components, such as brake caliper, spoiler bracket, engine bracket, etc. These components generally adopt a complex geometric structure, while maintaining or improving strength and performance, they realize lightweight.

Dalala

Dalala should be more unfamiliar to most of them. This is an Italian car company with its main business is the racing business. They cooperated with the 3D printing company Conflux to manufacture thermal exchangers for their third -level equations. Their newly designed 3D printing version of thermal exchanger has higher thermal conductivity and high temperature resistance.

Ferrari

Many cases have proven that 3D printed parts have a very obvious effect on racing and supercars. With the support of 3D printing, auto manufacturers can design and produce lighter, stronger, and more effective parts in a short time. Therefore, Ferrari also started using this technology and focused on the metal 3D printing. They optimized some of the original components and printed 3D again. Such as the piston of the engine, the brake pedal of the hollow structure, etc.
