Microstructures of bioactive glass scaffolds created by a variety of processing methods: (a) sol-gel; (b) thermal bonding (sintering) of particles (microspheres); (c) ‘trabecular’ microstructure prepared by a polymer foam replication technique; (d) grid-like microstructure prepared by Robocasting; (e) oriented microstructure prepared by unidirectional freezing of suspensions (plane perpendicular to the orientation direction); (f) Micro-computed tomography image of the oriented scaffolds in (e).
