Prototype production process Prototype production usually includes the following methods: 1. CNC production: First, according to the design drawings or prototypes, use appropriate materials (such as wood, plastic, metal, etc.) for programming, and then continue processing by CNC machine tools. 2. Silicone mold flipping: Make a prototype of the model (3D printing or CNC processing), process the prototype, and then copy the product. 3.3D printing: Print according to the drawings (some require disassembly first). There may be some defects on the printed surface, so polishing and trimming are required to improve the surface quality and accuracy of the model.

The role of prototypes in product design is obvious. It is an indispensable tool for designers and engineers in the product development process. By making prototypes, designers can visually evaluate the appearance, structure, and performance of the product, and engineers can better understand the product's characteristics and potential to make more precise decisions in the subsequent development process. At the same time, prototypes can also be used as a tool for communication with consumers and internal decision-making, helping companies to more accurately understand market demand and product development direction. Therefore, we should fully understand the role and use of prototypes in order to better apply them in the product development process.
