Bone scaffold for aiding bone regeneration in large bone defects should have following ideal characteristics; biocompatibility, biodegradability, bio-activity, high porous and interconnected-pore architecture, as well as, mechanical characteristics similar to the cortical bone for supporting loads. 3D printed Sr–HT (Sr–Ca2ZnSi2O7)–gahnite scaffold with hexagonal pore structure is an interesting bone scaffold meeting most of these ideal features. To explain, biocompatible, osteoinductive, and osteoconductive properties as well as unique high compressive strength are obtained from Sr–HT–gahnite, glass-ceramic, material. With hexagonal pore structure, the scaffold has compressive strength comparable to cortical bone balancing with high porosity and large pore size. Nonetheless, the scaffold…

Nerve conduits for peripheral nerve repair have progressed from simple silicon tubes to complex engineered scaffolds. Recent advances in scaffold fabrication have enabled the incorporation of neurotrophins, extracellular matrix components and various cells into scaffolds for enhanced biologic properties. Bioplotting is one of the emerging methods, where the scaffold material, in form of a solution, is dispensed from a needle, layer by layer forming a three-dimensional structure. It enables the use of a wide range of materials, ranging from synthetic polymers (like polycaprolactone, polyglycolic acid, etc.) to naturally occurring polymers like alginate, chitosan, etc. Notably, the use of hydrogels gives…
