3D printing technology is highly optimized for medical applications because metal and polymer based printing materials can easily produce patient-customized implants. Recently, photo-curable ceramic 3D printing materials have been actively studied to compensate for the high processing cost of metallic materials and the low mechanical properties of polymer materials. In the case of ceramic printing materials, ceramic powder is added to a photo-curable resin to form a slurry, and then photo-cured with a laser. In this study, the surface of zirconia powder was modified using a silane coupling agent and then used as a 3D printing material. In addition, we studied the mechanical properties and curing properties of ceramic 3D printing materials according to the ratio of ceramic material and polymer resin.
