Abstract = {{This article reports the first robocasting of a sol-gel based glass
   ceramic scaffold. Sol-gel bioactive glass powders usually exhibit high
   volume fractions of meso- and micro-porosities, bad for colloidal
   processing as this adsorbs significant portion of the dispersing medium,
   affecting dispersion and flow. We circumvent these practical
   difficulties, to achieve pastes with particle size distributions, high
   solids loading and appropriate rheological properties for extrusion
   through fine nozzles for robocasting. Scaffolds with different
   macro-pore sizes (300-500 mu m) with solid loadings up to 40 vol.\% were
   robocast. The sintered (800 degrees C, 2 h) scaffolds exhibited
   compressive strength of 2.5-4.8 MPa, formed hydroxyapatite after 72 h in
   SBF, and had no cytotoxicity and a considerable MG63 cells viability
   rate. These features make the scaffolds promising candidates for tissue
   engineering applications and worthy for further in vivo investigations.}},
