Abstract
Three-dimensional (3D) printing, an emerging rapid prototyping technology, has been widely used in biomedical field. 3D printing was originally used to construct the visualization models and molds in medicine. With the development of 3D printing in biomedical field, the technology was gradually applied in complex tissue regeneration and organ reconstruction. Artificial tissues and organs obtained by 3D printing are expected to be used for organ transplantation, new drug development and drug toxicity evaluation in the field of medicine and health care research. This paper describes the individualized application of 3D printing technology in liver surgery and introduces the research progress of 3D bioprinting technology in liver transplantation, drug metabolism and hepatotoxicity evaluation, and prospects its future development trend to provide a reference for further study.
