In the design of auto parts, due to the rapid prototyping characteristics of 3D printing, developers can use 3D printing technology to create conceptual models from computers in a matter of hours or days, and then directly convert 3D design drawings into real objects, reducing complexity. The mold opening process in component development also has higher precision, which makes the vehicle design and manufacturing cost low, the development cycle is short, and the production efficiency is higher.

Moreover, 3D printing allows for a variety of material selection, different mechanical properties and precise functional prototypes, enabling designers to correct errors and improve designs at any time in the early stages, avoiding corresponding errors as early as possible. Error avoidance and richer functional experiments through 3D printing speed up the production efficiency of components at the design level and save the labor and material costs of errors in R&D design.

On the other hand, for the current automotive industry, innovation can make the products meet the market demand continuously. The processing precision and the complexity of 3D printing are much higher than the traditional CNC machining, which can make it more complicated and more The design and subversive of traditional parts design can be realized. The more parts that can’t be processed by traditional machining processes, the more the three-dimensional printing is used, such as the more complex wheel; the surface lines, the more complicated body skin parts or Interior components; car hollow seats that are lightweight, safe and comfortable, all of which inspire new thinking about car design.
