With the rapid development of science and technology, the application of 3D printing technology in personalized drug manufacturing is becoming increasingly mature, providing innovative solutions for patients and the pharmaceutical industry. Due to the integration of the 3D printing process, there are more adjustable parameters, and the printing process needs to be analyzed and monitored so as to optimize the printing process and reduce the risk thus to ensure the quality of the product. Process analytical technology (PAT) can ensure the consistency between product quality and intended use through systematic control measures, solving the limitations, contingencies and lags associated with pharmaceutical batch sampling, so the pharmaceutical industry has begun to introduce PAT technology to co-manage the production process. Based on the above background, this paper aims to integrate current research findings, dentify the challenges and opportunities associated with the application of PAT, and provide references for industry practices and future research. This paper briefly introduces PAT-related regulations, model building methods, lists commonly used PAT tools, and summarizes the application of PAT in the process of drug 3D printing. Combined with the advantages of PAT and the current status of domestic and international applications, we also evaluates the current regulatory environment and analyzes the current challenges faced by 3D printed drugs and PAT.
