1. Design level

Traditionally, when designing a car, planners start with drawings, and then use design software to make the conceptual car shape into accurate data and 3D models. If you don't have 3D printing skills, the next step is clay modeling. Like a carpenter, the designer must first make the skeleton of the car by beating and beating, and then, like a mason, mix talcum powder, petroleum jelly, and industrial wax to make putty, and then apply it to the skeleton layer by layer. Finally, like an artist, scrape out the shape of the clay, make the final model, and see what the actual shape of the model on the drawing paper and computer is. This process is still a process in the handicraft era, which is time-consuming and labor-intensive.

With 3D printing technology, planners only need to input the 3D model made by the computer into the 3D printer, and the 3D printer can quickly print out the clay model in 3D, which can greatly improve the efficiency and enter the information age in one step. Not only the car body shell, but also various parts in the car, such as the shift handle, instrument panel, glove box, door handle, etc., have a process from computer to real object.

Using 3D printing technology, engineers realize the model planning on the computer, and designers can obtain the physical printing model in just a few minutes, and then every professional in the entire development team can modify it on the basis of the printing model, and Instantly share the improvement of the design scheme with other people in the team, realize "what you see is what you get", and greatly increase the efficiency of car design.

2. Development level

The biggest advantage of 3D printing technology is that it can produce high-precision and complex-looking parts conveniently and quickly, and the trolley has many high-precision parts with complex shapes. For high-end cars with relatively small batches that cannot meet the mold opening plan, 3D printing can also directly produce some materials to meet the needs of parts and reduce costs, such as some parts of F1 racing cars, luxury cars, and supercars.

For parts that need to be produced in large quantities, 3D printing may not be applicable due to material and cost reasons. However, 3D printing can produce application parts, especially some parts with very complex shapes, high precision requirements, and repeated debugging. 3D printing can quickly produce the most suitable parts to ensure that the finalized production is the selection of the best parts, and the resulting advantages are to improve the overall development efficiency, shorten the time to market cycle, and reduce time and cost.

In summary, 3D printing technology can greatly reduce the cost of car development and manufacturing, improve work efficiency, and reduce the development time of new models and new parts. These will be reflected in the price and quality of cars, with better quality and better technology. Perfect and cheaper cars will appear due to the popularization of 3D printing technology, and consumers will also benefit from it.
