Calcium Phosphate Cement(CPC) scaffolds fabricated by 3D printing are increasingly used in the field of bone tissue repair. Generally, production rate of CPCs are low since the amount of calcium phosphate compounds is small in conventional raw materials, such as bovine bone and porcine bone. On the other hand, cockle shell contains more than 99% of CaCO3, one of the main constituents of CPC, in the form of amorphous aragonite which has excellent bioavailability. Therefore, in this study, cockle shell powder and β-TCP based CPC scaffolds were fabricated through an extrusion method using nozzles which are narrower than conventional one for CPC 3D printing. Their morphology and biocompatibility were investigated. With this method, high-added value can be created for fishing villages due to the recycling of natural materials which is thrown away as marine waste.
