摘　　要：光固化陶瓷3D打印中,以最终浆料的黏度值作为流变性的指标。考察了固相材料SiO2颗粒大小分别为纳米级、亚微米级以及微米级三种浆料在不同温度下黏度值的变化情况。实验结果表明:粒径大小对黏度值的大小有显著影响,不同粒径下呈现出不同的流变性特征;温度对流变性也有重要影响,较低温度往往获得的黏度值较大。In 3D printing of light-cured ceramics,the viscosity of the final slurry is used as an indicator of rheology,and the changes in viscosity values of three kinds of silica particles of nanometer,submicron and micron particle sizes are investigated at different temperatures.The experimental results show that the particle size has a significant effect on the viscosity value.Different particle sizes show different rheological characteristics.Temperature also has an important effect on rheology.Lower temperatures tend to obtain higher viscosity values.
