Abstract:
As an emerging bio-additive manufacturing technology, 4-Dimensional bioprinting introduces the dimension of time into traditional 3D printing, enabling printed structures to change their shape or functionality under specific stimuli. The essence of 4D bioprinting lies in its ability to mimic the dynamic nature of biological tissues, offering new possibilities in the fields of tissue engineering, drug delivery systems, and artificial organs. However, clinical applications of this technology also face certain challenges. This article introduces types and characteristics of intelligent materials, as well as the research progress in 4D bioprinting technology in such orthopedic fields as bone defect repair, cartilage repair, and fracture fixation devices.
