Direct ink writing of highly bioactive glasses

Direct ink writing (DIW) or Robocasting, is an additive manufacturing technique that offers the opportunity to create patient specific bioactive glass scaffolds and high strength scaffolds for bone repair. The original 45S5 Bioglass® composition crystallises during sintering and until now, robocast glass scaffolds contained at least 51.9 mol% SiO2 or B2O3 to maintain their amorphous structure. Here, ICIE16 and PSrBG compositions, containing
