The invention discloses a slurry composition for 3D printing of a zirconia-based denture. The slurry composition is composed of the following components: zirconia ceramic powder; a binder; the zirconium oxide ceramic powder is prepared from the following components: Al2O3, ZrO2, Si3N4 and SiC; the binder is composed of the following components: a binder; a plasticizer; a dispersant; a lubricant; the solvent is a mixture of one or more of ionized water, alcohol, chloroform, acetone and tetrahydrofuran in any proportion. The mixed composition is used as zirconia ceramic powder slurry, a preliminary model is formed in a 3D printing mode, the binder is good in fluidity and high in extruded material continuity during extrusion, when the preliminary model is formed, the strength of the model is high, operation can be conducted on complex parts, forming can be conducted in a thermal degreasing mode, and the production cost is low. And in the forming process, generated internal stress is small, escaped gas is safe and non-toxic, and safety is high.
本发明公开了一种3D打印氧化锆基义齿的浆料组合物，由以下组分组成：氧化锆陶瓷粉；粘结剂；溶剂：所述的氧化锆陶瓷粉由以下组分组成：Al2O3、ZrO2、Si3N4、SiC；所述的粘结剂由以下组分组成：结合剂；增塑剂；分散剂；润滑剂；所述的溶剂为离子水、酒精、氯仿、丙酮和四氢呋喃中的一种或任意多种的任意比例的混合物。本发明所采用的混合组合物作为氧化锆陶瓷粉浆料，通过3D打印的方式形成初步的模型，该粘结剂在挤出时，其流动性好，挤出料连续性强，在形成初步模型时，模型的强度高，可针对复杂的部分进行操作，可采用热脱脂的方式进行成型，成型的过程中，所产生的内应力较小，逸出的气体安全无毒，安全性高。
