Abstract:
Porous CaSiO 3 ‐CaSO 4 composite scaffolds were successfully prepared by 3D gel‐printing (3DGP) technology in this study. In order to further improve the degradation performance of pure CaSiO 3 scaffolds, the effect of different CaSO 4 doping contents on CaSiO 3 ‐CaSO 4 composite scaffolds was studied. The results show that when the porous composite scaffolds were placed in simulated body fluid (SBF) for 5 weeks, the weight loss rate was 2.41% (CaSiO 3 ‐1%CaSO 4 ), 3.97% (CaSiO 3 ‐3%CaSO 4 ), 4.18% (CaSiO 3 ‐5%CaSO 4 ), 6.87% (CaSiO 3 ‐7%CaSO 4 ), and 12.93% (CaSiO 3 ‐9%CaSO 4 ), respectively, which could be concluded that CaSO 4 doping has a significant effect on improving the biodegradability of CaSiO 3 scaffolds. And CaSO 4 doping can also effectively improve the compressive strength of composite scaffolds and that of CaSiO 3 ‐3%CaSO 4 composite scaffolds was tested as 54.67 MPa, and the shrinkage rate of porous composite scaffolds was nearly 11.4%, which meets the application requirements of bone repairing engineering.
