Ye Junxiang: Application of 3D printing in the automotive industry

3D printing is currently hot in the world, especially in the past two years, including the promotion of the 3D printing industry by the government in our country. Today I mainly talk about the application of 3D printing technology in the automotive industry. This 3D printing is industrial. Level is not the desktop level that ordinary people see. This is for the children to see at home. It is ok to play.

I have divided the four parts and reported today's speech. The first part is the company's explanation. What is the current status of 3D printing in the current automotive industry? The 3D printing process, we develop a more mature process to introduce to everyone, and finally In the automotive industry, a report on the various levels should be reported to you. Our Sapu company formulates air conditioning and 3D printing business, and the automotive field relies on the TS16949 process. We mainly talk about the application of 3D printing technology.

Let's take a look at this statistic. The data may not be accurate. He is from the Internet or print media. It basically reflects a trend that is that trouble 3D printing technology accounts for 32% of the global automotive industry. Let's take a look. This is the world's first 3D printed car that can be driven. The current total is 555 kilograms. What is the difference between this 3D printing car and the traditional car? This is a sports car built by a US company for 44 hours. The whole car price. And the body seat, the center console, the instrument panel, the engine cover are all done in 3D printing. This is Lamborghini's sports car bumper, steering wheel and seat cover are also realized by 3D printing technology. This is a sports car. What is different from the previous ones is that it uses 3D printing technology to print 70 complex nodes. It is connected by carbon fiber sheets. The meat is manually installed, which is 30 minutes before and after. Complete the chassis installation of this car, the chassis weighs only 69 pounds.

Peugeot uses 3D printing acoustic interior, Citroen is also applying 3D printing technology, you can see some effects, but also through the processing of the effect, Martin also uses 3D printing technology to complete the development of the vehicle, GM because of similarities, We are simpler at the moment. What is the current situation? The market competition is intensifying and the life cycle of products is shortening. It is the importance of various OEMs to realize the cost control of R&D speed. On the one hand, it is the pressure to shorten the development cycle. On the one hand, it is the influence of materials, structure, process and other factors. It uses 3D printing to have high flexibility, is suitable for complex shapes and structures, and is suitable for combination materials to overcome the insurmountable state of traditional industries. The use of 3D printing technology is to subvert the traditional industry.

Car dashboard, forward direction, lamp accessories, intake manifold, etc., is a better display of the material and performance of the product, we currently use 3D printing technology, all parts are technology, this 3D printing technology has a time in what The place is that in the product development stage, it has its own unique advantages, in the research and development stage. 3D printing technology has just been said. In August of this year, a special lecture held by Premier Li Keqiang was that advanced manufacturing has 3D printing. This topic was personally selected by Premier Li Keqiang. Since the 13th year of the Ministry of Science and Technology's 863 program, 3D printing has been included in it. After the Beijing Municipal Science and Technology Commission first listed 3D printing technology as a government key support project in 2014, other provinces and cities have no exceptions. In the process of professional development, the current competition is more consistent, that is, there is government support, that is, the development of 3D printing technology is promoted all over the world. There are many types and methods of 3D printing, but it is better in industrial use. SLS, FDM, is quite mature in the automotive field and is also relatively good to use.

It is the simple process of SLS, SLA. You can see that 3D printing has become a shape. You give me 3D printing technology data to structure your data. Because of the process, 3D printing is done by 3D printer . This is the part of the mouse that is mechanically completed. Other parts need manual prioritization. We often say that many of our companies buy 3D printers. They don’t use them well. What else is there? I think that I only have digital models and machines. There are materials that can be processed. This is not the case. Every 3D printing process is similar, but there must be a lot of early manual intervention, manual design, and finally finished by the machine, which is the part that receives the post-processing and forms a perfect It can be used, not as a component, which needs to be handled manually. We have always stressed that it is not 3D manufacturing, it is 3D printing process development, not simple 3D printing manufacturing.
