3D Bioplotter Research Papers

Mesoporous bioactive glass scaffolds (MBG_Scs), based on 80% SiO2–15% CaO–5% P2O5 (in mol.%) mesoporous sol–gel glasses substituted with Ce2O3, Ga2O3 (both 0.2% or 1.0%) and ZnO (0.4% or 2.0%), were synthesized by combination of evaporation-induced self-assembly and rapid prototyping techniques. Cerium, gallium and zinc trace elements were selected because of their inherent beneficial biological properties. Fabricated scaffolds were characterized and compared with unsubstituted scaffold (B_Sc). All of them contained well interconnected ultralarge pores (pores >400 μm) ideal for vascular ingrowth and proliferation of cells. Macropores of size 100–400 μm were present inside the scaffolds. In addition, low-angle X-ray diffraction showed…
