The excellent biocompatibility and biodegradability of sodium alginate give it wide applications in the field of biomedicine. How to use sodium alginate to manufacture biomedical materials

tissues and organs has become one of the important challenges to promote its excellent performance in medical applications. 3D printing technology gets the advantages of controllable design of structure and high utilization rate of materials

which can realize personalized manufacturing. In this paper

the latest applications of 3D printing sodium alginate based materials in bone tissue engineering scaffolds

artificial blood vessels

in vitro

construction of tumor models

artificial organs and other aspects in tissue engineering were discussed and prospected.
