Medical 3D printing has been a trendy technology with a linear increase in heat in recent years. 3D bioprinting has spawned an industrial chain in the form of medical models, diagnostic and therapeutic instruments, rehabilitation aids, prosthetics, teeth and artificial joints across the first and second levels. The industry chain has been formed. However, there are many problems related to the approval of 3D printing products, national policy decisions on such products, as well as bottlenecks encountered in the process of product uptake in terms of technology and materials, product prices, etc., such as printing human tissues and organs, and so on. Then, if the breakthrough of these bottlenecks and master the direction of the entire market and the core technology and have the core market competitiveness has become the key to a long-term foothold of the enterprise, but also clinicians and researchers are generally concerned about the problem.
