Abstract: In recent years, 3D printing technology has been widely used in many fields, such as aerospace materials and accessories, biomedical medical devices, environmental art models and so on. This technology can be formed in one step, with simple process as well as flexible and adjustable product parameters. At present, it has been used for the research of personalized drug preparations such as multi-drug compound preparations, sustained controlled-release preparations, high-load tablets and special-shaped tablets. This paper summarized the classification, principle and application of several commonly used 3D printing technology in the field of solid tablet preparations, and its development prospect was analyzed and summarized to provide references for its research in the field of pharmaceutical preparations.
