Shape memory polymers(SMPs) as a class of smart materials, can remember various shapes and return to their original shapes upon external stimuli. 4 D printing that is the combination of 3 D printing and SMPs has been used for fabrication of various SMPs in many areas of science and technology. At present, 4 D printing technology plays an important role and shows promising applications in biomedical field. 4 D printing breaks through the technical bottleneck of customization in traditional medical field and provides a new opportunity for the further development of biomedical field. In this article, we review the research progress of SMPs, 3 D printing technology and 4 D printed SMPs used in biomedical science. Moreover, we introduce some typical biomedical applications of 4 D printing of SMPs. Furthermore, we summary the application prospects, existing problems and future development direction of 4 D printed SMPs in biomedical field.
