Abstract:Tissue engineering scaffolds play promising role in the repair of human bone defects, despite of unsatisfactory clinical results by the conventional methods. In bone tissue engineering, the preparation of high-performance scaffolds is the focus of research. This field mainly produces bone tissue engineering scaffolds with ideal shape, structure, as well as physical, chemical and biological characteristics to improve the biological performance of scaffolds and improve the effect of repairing bone defects. 3D printing technology is widely used in many industries of biomedical engineering. By customizing the shape and structure, 3D printing technology has the potential to prepare ideal bone tissue engineering scaffolds with bionic macro or micro structure, reasonable mechanical properties, and good cell or tissue compatibility. This paper briefly reviewed the research progress of different types of bone tissue scaffolds prepared by 3D printing, and introduced the latest idea of designing and manufacturing bone tissue engineering scaffolds by 3D printing.
