3D printing can be said to be a revolutionary technological development. In recent years, it has been pushed to the forefront of the market and has been applied in many fields. We can even use a small commercial 3D printer in the shopping malls around us to transfer our own The image is printed out as a souvenir. Nowadays, with the continuous development of 3D printing technology, it has more and more applications in the field of auto parts. After all, it is a major breakthrough in the auto industry.
The advantage of 3D printing is that compared with CNC machining in traditional manufacturing, it has many advantages. It can save many costs in the research and development of vehicle parts through 3D printing technology, greatly shorten the research and development cycle, and improve production efficiency. Then 3D printing is in today What are the applications in the automotive industry in China? What are the advantages compared to traditional crafts?



The application of 3D printing in the field of automotive R&D and design:

In terms of auto parts design, due to the rapid prototyping characteristics of 3D printing, R&D personnel can use 3D printing technology to create a conceptual model on a computer within a few hours or days, and then directly convert the 3D design drawing into a real object, reducing complexity The mold-opening link in the development of parts and components also has higher precision, which makes the vehicle design and manufacturing cost low, the development cycle is short, and the production efficiency is higher.
In addition, 3D printing allows a variety of material choices, different mechanical properties, and precise functional prototype production, enabling designers to correct errors and improve the design at any time in the early stage, and avoid corresponding errors as soon as possible. Error avoidance and richer functional experiments achieved through 3D printing speed up the production efficiency of parts at the design level, and save the manpower and material costs consumed by errors in R&D and design.
On the other hand, for the current automotive industry, innovation can make products continue to meet market demand. The processing accuracy and achievable complexity of 3D printing are much higher than traditional CNC machining, which can make it more complex and more complex. Design and subversion of traditional parts design can be realized. The more parts that cannot be processed by traditional processing technology, the more 3D printing is used. For example, wheels with more complex shapes; body skin parts or interior parts with more complicated surface lines and textures; car hollow seats with light weight, safety and comfort, etc., all inspire people to car design New thinking.

3D printing can achieve personalized customization of cars:

Although there are many models on the market to choose from, after all, the same model is a mass-produced model produced in a mold, and you will never be unique. With the continuous maturity of 3D printing technology, it is believed that one day in the future, it will be possible to realize the universal application of personalized customization of the whole vehicle based on 3D printing technology. Although the personalized customization of the vehicle based on 3D printing seems to be very far away, there are already companies that are committed to providing consumers with the opportunity to design their own 3D printed cars.

The application of 3D printing in power lithium batteries:

A research team led by Rahul Panat, associate professor of mechanical engineering at Carnegie Mellon University, and Missouri University of Science and Technology have developed a new method of 3D printing battery electrodes, which can create microscopic structures with controlled pores. Metal structure to achieve higher battery capacity and charge and discharge speed.
In lithium-ion batteries, electrodes with porous structures can bring greater storage capacity. This is because this structure allows a large amount of lithium ions to enter the electrode, which can achieve higher electrode utilization and higher storage capacity. In ordinary batteries, 30% to 50% of the electrodes are not available. We have overcome this problem through 3D printing technology. The microscopic electrode structure manufactured by 3D printing can allow lithium ions to be transmitted more effectively in the electrode, which will also improve the charging speed of the battery. The microscopic metal structure used as a lithium-ion battery electrode can increase the specific capacity by four times, and the area capacity has increased by two times compared with traditional solid batteries.

In short, at present, the application of 3D printing technology in the field of auto parts can make the development cost of parts lower and more efficient. In the future, with the continuous maturity of 3D printing technology and the reduction of cost, 3D printing of the whole vehicle may be realized, and it will be able to create an exclusive vehicle for each consumer according to different needs. The more complex parts and components achieved by 3D printing can also improve the economy and power of the vehicle.
