The invention relates to the field of ceramic, and discloses a 3D printing ceramic material based on photo-curing and a preparing method thereof. The ceramic material is prepared by conducting 3D printing, photo-curing and sintering on ceramic ink; the ceramic ink is prepared from, by weight, 60-80 parts of ceramic powder, 2-4 parts of epoxy modified beta-cyclodextrin, 0.1-0.5 part of cation photoinitiator, 0.5-2 parts of dodecyl trimethyl ammonium chloride, 3-7 parts of 25-35wt% hydrogen peroxide, 10-20 parts of absolute ethyl alcohol, 2-6 parts of glycerol and 2-8 parts of deionized water. The 3D printing ceramic material has a quick-curing capability, and the prepared ceramic ink is low in viscosity, high in mobility and suitable for ink jetting 3D printing. 本发明涉及陶瓷领域，公开了种基于光固化的3D打印陶瓷材料及其制备方法，该陶瓷材料由陶瓷墨水3D打印、光固化、烧结后制得；所述陶瓷墨水包括以下重量份的原料：陶瓷粉60-80份，环氧改性β-环糊精2-4份、阳离子光引发剂0.1-0.5份、十二烷基三甲基氯化铵0.5-2份，25-35wt%的双氧水3-7份，无水乙醇10-20份，丙三醇2-6份和去离子水2-8份。本发明的3D打印陶瓷材料具有快速固化的能力，并且配制得到的陶瓷墨水粘度低，流动性好，适于喷墨3D打印。
