Restoration of bone defects requires creative strategies that can be applied to the hierarchical structure of bone tissue from the nanoscale to the macro. For this purpose, we have to select materials that provide porous structures, with cell compatibility, and appropriate mechanical strength and degradation rate with. Based on this, OmidAfrinan Co. has introduced a composite bioink named Osteo-Ink® that has the desired bioactive properties and is ideal for 3D bioprinting of bone tissue scaffolds
