The sludge model is a car body model with a clay sculpture in the traditional body design, which is used to express the overall effect of the car shape for designers and decision makers to verify. However, since it mainly relies on pure hand-made, this requires a high degree of technical skill for the operator, and has a long production cycle and high cost. And 3D printing to make automotive molds is expected to accelerate the car development process
In the past, the production process of the sludge model was very cumbersome. The stylist first had to make the model initial embryo (the body frame made of wood or foamed plastic cutting), and then proceeded by filling the sludge, the first scraping mud, and the fine scraping sludge. The shape is shaped, the shape of the car is sculptured according to the specified proportion, and the real headlights, tires and other components are matched. In order to make every detail of the car more rigorous, some models will also be coated with metal film or spray paint on the surface, which is very similar to the real car, and it is convenient to adjust and modify more intuitively. The car's shape is relatively complex, composed of many smooth curved surfaces. It usually takes 3-4 months to make a full-size car model, and a full-size internal sludge model takes 2-3 months. In contrast, based on the digital manufacturing model, 3D printing technology has obvious advantages in the field of automobile complete vehicle and product design. It effectively complements the traditional sludge model making process in the new product development section of the automobile, which can shorten the R&D, design and production cycle of new products and enable new car development. The trial production is expected to drop sharply.
In addition, for consumers to customize their needs, automotive companies can also provide cost-effective solutions using 3D printing technology. For example, consumers want to make their new car look and interior different. If you use a traditional process to open a new mold, the cost is hundreds of thousands of dollars, but using 3D printing for rapid prototyping, no additional molds are needed, and the production process is minimized. And can reduce costs
