Materials Comparison of 3D Printed Scaffolds for Bone Tissue Engineering Applications

In recent years, 3D printed bone tissue engineering scaffolds have developed rapidly in the field of bone defect repair, and their materials research, development and preparation are very prospective, with a significant long-term clinical application effect, which is expected to solve further the problems of vascularization disorder, osteogenesis difficulty and cell activity maintenance during the bone regeneration process. The application advancement of frequently used 3D printing bone scaffold materials is presented in this review by extracting relevant literature from each journal database and merging it with current research. The application effects of different materials are compared to improve the standard and process specification of 3D printing materials and further enhance the recognition and satisfaction of clinical treatment.
