Topic title: Research on additive manufacturing technology for bone tissue engineering applications

Abstract:

More than 80% of the bone remodeling process occurs in cancellous bone. Its internal complex structure and remodeling process ensure the excellent self-repair ability of bone tissue. However, when the length of the bone defect reaches 1.5 times the diameter of the diaphysis, it will exceed the critical value of autologous repair, causing the bone defect to be unable to heal itself. Facing the demand for bone scaffolds in the treatment of clinical bone defects, through a combination of simulation and experiment, the impact of process optimization of room temperature inkjet printing and laser selective sintering on the printing accuracy and performance of bioceramic bone scaffolds and metal bone scaffolds were studied. This study provides guidance for process selection of bone scaffolds made of different materials.
