WebJan 1, 2024 · A functionally graded composite scaffolds consisting of FG-Ti filled with SF sponge was developed. The SLM-produced FG-Ti with the radial graded porous structure exhibited superior mechanical properties than HP-Ti. Composite scaffold with SF sponge filled in showed better cell attachment, growth and proliferation than FG-Ti. WebTo evaluate the degradability, graded porous scaffolds compared with homogeneous scaffolds were placed into a Tris-HCl buffer solution (pH = 7.4) for 28 days. It was found that both scaffolds presented the same degradation trend, and the graded porous structure did not change the original degradability of the scaffold.
