Abstract
Three-dimensional (3D) micro-structure of bone scaffold played an important role in cell adhesion and reproduction. The introduction of 3D measuring techniques in bone research made it possible to capture the actual architecture of bone scaffold without assumptions of the structure type. Two bone scaffolds fabricated by FDM and SLS were reconstructed and analyzed, then were compared with 3D structure indices of canine femur specimens. Based on the direct 3D analysis, there were obvious differences between two scaffolds in structural characteristics. Scaffolds prepared by FDM showed a denser and plate structure, a lower porosity, the trabecular bone was thinner. While scaffolds prepared by SLS showed a rod-shaped structure, were closer to real canine femur specimens, had a higher inter-connectivity. Scaffolds prepared by these two methods had no significant anisotropy.
