3D printing light-cured ceramic particle and preparation method thereof
The invention provides a 3D printing light-cured ceramic particle and a preparation method thereof. The 3D printing photocuring ceramic particle comprises a ceramic matrix; wherein the surface of theceramic matrix is coated with a coating layer; and the coating layer is a sintering aid layer, and the sintering aid layer coats the ceramic matrix according to the decreasing order of the refractiveindexes of the sintering aid components. The 3D printing light-cured ceramic particle is prepared by a precipitation method, the thickness and components of the coating layer can be accurately controlled, and meanwhile, a proper coloring agent is added to adjust the light absorption coefficient, so that the 3D printing light-cured ceramic particle is more suitable for the requirements of a ceramiclight-cured molding technology.
本申请提供一种3D打印光固化陶瓷颗粒及其制备方法。3D打印光固化陶瓷颗粒包括：陶瓷基体；包覆于所述陶瓷基体表面的包覆层；且包覆层为烧结助剂层，烧结助剂层按烧结助剂成分的折射率递减次序对陶瓷基体进行包覆。上述3D打印光固化陶瓷颗粒通过沉淀法制得，包覆层的厚度和成分可以精确控制，同时添加适当着色剂，调整其吸光系数，使其更适合陶瓷光固化成型技术的需求。
