Preparation method of photocuring 3D printing multi-material ceramic structural member
The invention relates to the technical field of ceramic 3D printing, in particular to a preparation method of a photo-curing 3D printing multi-material ceramic structural member, which comprises the following steps: sequentially adding ceramic powder A, mixed ceramic powder and ceramic powder B into a mold, preparing light-cured ceramic slurry with gradient content with a light-cured monomer, a dispersing agent, a light initiator and a low-molecular-weight plasticizer respectively; the photocuring ceramic slurry is subjected to integrated photocuring printing according to the solid content gradient sequence through a multi-material photocuring 3D printing forming machine, and a multi-material ceramic structural part green body with the solid content gradient is prepared; preparing a multi-material ceramic structural part green body with solid content gradient; and degreasing and sintering the multi-material ceramic structural member green body in argon to obtain the multi-material ceramic structural member. According to the method, the problem that in the photocuring 3D printing forming process of the multi-material ceramic structural part, in the traditional degreasing technological process, due to the large difference of different ceramic material green body components, defects are likely to be generated is solved.
本发明涉及陶瓷3D打印技术领域，具体涉及一种光固化3D打印多材料陶瓷结构件的制备方法，包括如下步骤：将陶瓷粉体A、混合陶瓷粉体以及陶瓷粉体B依次，分别与光固化单体、分散剂、光引发剂和低分子量塑性剂配制成梯度含量的光固化陶瓷浆料；将光固化陶瓷浆料利用多材料光固化3D打印成形机，按照固含量梯度顺序进行一体化光固化打印，制备固含量梯度的多材料陶瓷结构件生坯；制备固含量梯度的多材料陶瓷结构件生坯；将多材料陶瓷结构件生坯在氩气下进行脱脂，烧结，制得多材料陶瓷结构件。本发明解决了光固化3D打印成形多材料陶瓷结构件中，传统脱脂工艺过程中由于不同陶瓷材料生坯组分差异大而导致的易生成缺陷的问题。
