Professor Wu Qiyao, chief expert of China Medical Device Industry Association, commented:
1. Biying 3D instant printing system is a good project with practical clinical application value;
2. Have sufficient strength to explore the domestic market and promote it in a wide range of domestic orthopedic hospitals;
     And on the premise of having a stable domestic market, go abroad to explore the international market;
3.The clinical effect of printing external fixation braces is good and the operation is simple and fast
4. The best medical device products are products that use the most practical technology and can get the best results.
     It should be cost-effective. Biying 3D instant printing system is such a good product.
