In the past 20 years, additive manufacturing technology has achieved rapid development and is widely used in consumer electronics, automobiles, aerospace, medical and health fields. In the automotive industry, from 3D printing models to customized small-scale production and operation, 3D printing technology is mainly applied in the production design of vehicle OEM companies. Is there still broader development space for 3D printing technology in the automotive industry?

3D printing is widely used in the design field

Automotive manufacturing is an important application field of metal 3D printing technology. Using 3D printing technology, auto designers can quickly manufacture prototypes and accelerate the efficiency of new car research and development; Small batch production of parts can shorten the supply chain and save costs, and 3D printing can be an important complementary technology in the automotive industry. In addition, the unique advantages of 3D printing in manufacturing complex parts can simplify the number of automotive parts, reduce weight, and save materials.

In terms of design, using 3D printing technology, designers can produce conceptual models in hours or days. Due to the Rapid prototyping characteristics of 3D printing, automobile manufacturers can apply it to the research and development of automobile shape design. Compared with the traditional hand made clay model, 3D printing can more accurately convert 3D design drawings into real objects in a shorter time and improve the production efficiency of Automotive design. Currently, many manufacturers have begun to utilize 3D printing technology in their design, such as BMW and Mercedes Benz design centers.

In terms of materials, 3D printing allows for a variety of material choices. Different mechanical properties and precise functional prototype production allow manufacturers to correct errors and improve designs at any time in the early stages, minimizing error costs.

In terms of fixtures, 3D printing technology provides a fast and accurate method, significantly reducing the cost and time of tool production. As a result, automakers have rapidly improved their production capacity, efficiency, and quality. The application of 3D printing for production tools, such as water-soluble inner cores, carbon fiber wrapping, and injection molding, can help enterprises achieve rapid small batch tool customization, reduce costs, and shorten product launch time.

Especially in the design and production process of automotive components, with the help of 3D printing technology, manufacturers can achieve small batch customization of components and production automation, as well as the creation and manufacturing of complex geometric shapes such as organic shapes, hollow and negative stretching. 3D printing can quickly produce components with complex shapes, and when problems arise during testing, modifying the 3D file and reprinting can be used for retesting.

With the rapid increase in the application of 3D printing technology in the automotive industry, it is predicted that the market size of automotive 3D printing is expected to reach 4.3 billion US dollars by 2025.
