Bioceramic scaffolds with excellent biocompatibility and bioactivity similar to natural bone tissue are widely used for bone repair. However, currently available bioceramic scaffolds lack a tailoring degradability, which should match new bone in growth rate affected by defect location, age and health of patients. The customizing the degradability of porous composite bioceramic scaffolds is a formidable challenge in regenerative medicine.
This study proposes a novel design strategy to prepare gyroid-structured composite bioceramic scaffolds using digital light processing (DLP) 3D printing technology. Additionally, the effect of scaffolds on bioactivity and tunable degradability was analyzed to assist people with orthopaedic conditions. We believe that our study makes a significant contribution to the literature because it focuses on achieving the desired bioactivity and degradability using both material and structural design. In addition, it uses DLP technology to obtain fine resolution, which is helpful in understanding the scaffolds with complicated features.
