Ceramic cores have an impact on the precious casting of the engine hollow blades. 3D printing technology, as a novel generation of molding technology, is replacing the conventional ceramic core manufacture process due to the advantages of no mold, short manufacturing cycle, and high accuracy. This review summarized the existing 3D printing technologies for ceramic cores such as light-curing technology, selective laser sintering, direct-write forming technology and layered extrusion, and discussed the current research work on the performance optimization for ceramic cores prepared by 3D printing based on their shortcomings (i.e., low printing accuracy, poor compatibility between mechanical property and porosity, and anisotropy in structure and property). In addition, the future development of this technology was also prospected.
