The medical device prototype model is the first step in verifying the feasibility of medical device products. It is the most direct and effective method to discover the design defects of medical devices and products, and can be improved until the defects of individual prototypes are found. Often, only a small number of trial runs reveals that batch processing is not enough to improve the product. The design of medical device prototypes cannot be perfect. Once a defect is found, it may not be directly used in small-scale medical production, wasting time, manpower, and material resources. By only producing a small number of medical device samples, the production cycle is short, the consumption of manpower and material resources is small, and the shortcomings in product design and production can be quickly found, which provides sufficient support for improving the mass production of medical device prototype products.CNC processing: CNC machine tools are used to control CNC machine tools for cutting, engraving and other processing. It has the advantages of high precision, high efficiency, and good repeatability. It is often used to make high-precision and complex-shaped prototypes.3D printing By superimposing and printing the CAD 3D model layer by layer, an accurate model can be produced. The advantages of 3D printing are short production cycle, no need for cutting and other processing techniques, and support for multiple material choices, etc., but its disadvantage is that the accuracy is relatively low, and the prototype model made on medical equipment with high precision requirements may not be suitable.
