Generally, new products that have just been designed need to be prototyped, because the newly designed products will have some deficiencies in some ways. By making prototypes to find out these deficiencies, and then gradually improve them, and design a perfect one. The product; it is also a very critical link before the product opens the mold. Don't open the mold rashly without making a prototype model.　　Plastic is a very good prototype material. Choosing 3D printing plastic materials to make prototypes is not only low cost, but also has the advantage of easy production and processing, so it is very common in the prototype manufacturing industry. A variety of plastic prototype models have a stronger product display, and can also carry out structural certification for Ru0026D personnel as soon as possible, and accelerate the development of new products.　　 No matter what material is selected to make the prototype model, it should be carried out in accordance with the 3D drawings and structure drawings of the product, so that it can be more prominent in the actual effect level. Plastic materials are very common in the plastic prototype manufacturing industry. If the product is to make structure and appearance models, photosensitive resin materials can be used for 3D printing. If the product is for performance prototypes, nylon materials can be used for 3D printing.
