The important work in the early stage of design lies in obtaining human body data, developing digital material selection and reducing resource waste. For textile and clothing products, the key link in actual production is to ensure the fit between clothing and human body and make clothing comfortable. This requires designers to know the physical characteristics of consumers in advance and accurately measure the subtle differences in different parts of people with different physical characteristics with the help of professional three-dimensional scanning equipment. The traditional size can only give a general reference range, but it can't really be tailored.

At present, with the data verification system, designers can directly locate different customer groups, and even carry out comprehensive design for some small groups to complete personalized customization. Specifically, before the order is confirmed, it can be reasonably modified according to the physical characteristics of the human body and the preferences of consumers, and finally a three-dimensional basic model can be obtained, thus avoiding the trouble of repeatedly trying on and adjusting in the traditional manufacturing field. After locking the basic size, height and bust of the target crowd, in order to avoid wasting resources, it is necessary to complete the basic clothing model creation and material rendering according to the customer's design intention, and then complete the preliminary design work after completing the basic material selection and material collocation.

2. Mid-design

In the middle stage of design, 3D printing technology can also be used for all-round protection. In the traditional fashion design process, after the basic design is completed, customers need to try it on, and then repeatedly modify and adjust it according to their own needs and comfort, and then they will not reach the customer's satisfaction threshold because the effect is not up to standard, or even cancel the order. This is also a major drawback of traditional fashion design, which limits the development of traditional fashion design. Three-dimensional virtual template design can be completed in virtual space. After cutting, the technically processed drawing is pasted on the design sample drawing, and the sample drawing with the same scale is rendered in the virtual space. After clicking on try-on, you can present and apply some dynamic commands on the virtual mannequin. For example, it can simulate the clothing effect when some arms are drooping or walking, or the change of clothing comfort when people bend down and squat. , intuitively embodies the characteristics of clothing.

For a long time, the modification of clothing production has been an important issue in production. Repeated revision will not only waste a lot of manpower and material resources, but also affect the relationship between customers and orderers. With the help of 3D printing technology, the virtual clothing method can be completely completed by computer equipment in the mid-term design stage, and the data can be changed. After the modification of materials and styles, the specific effects of clothing materials in different light and angles can be presented, which will further improve the production process in simulation of machining, shorten the design time, reduce the consumption of human resources in processing, and save expenses and create value for the subsequent clothing configuration.

3. Late design

The late stage of design refers to the actual technical production and processing links, and the quality of clothing is closely related to the final sales. Relying on the support of 3D printing technology, clothing production efficiency and technological innovation level can be improved. At present, all the materials that can be seen in the market can be printed with 3D exclusive equipment, so that the computer software station can restore the characteristics of the items in equal proportion according to the data of the 3D model. The fineness of the model determines the authenticity and appearance characteristics of the object, which can meet the design requirements highly. Designers can understand the basic characteristics and printing requirements of clothing only according to the three-dimensional model. For example, before the production of out-of-season clothing, it is better than the traditional design to make a virtual technical scheme on the network and then mass production after being recognized by customers.
