RESUMEN
With the development of high and new technology, such as material chemistry and computer technology, the formulation process is also constantly innovating and improving. In recent years, 3D printing technology has become a research hotspot in the formulation industry. Different from traditional preparation methods, 3D printing technology can realize personalized production and solve storage problems of drugs. Because of its advantages of simple production, convenient carrying, low cost and strong patient compliance, it may change the design and production mode of drugs in the future and have good development prospects in the field of preparation. This paper reviews principles, the latest research progresses, advantages and challenges of 3D printing by searching CNKI, SCI, Springer databases and collating relevant literatures, and forecasts the development of 3D printing technology in the field of traditional Chinese medicine preparations, aiming to provide some references for the application of the technology in the traditional Chinese medicine preparation industry.
