Ceramic slurry for 3D printing, ceramic part and preparation method of ceramic part
The invention provides ceramic slurry for 3D printing, a ceramic part and a preparation method of the ceramic part, and belongs to the technical field of 3D printing. The ceramic slurry comprises a first component and a second component; the first component comprises ceramic powder and an organic binder; wherein the content of the ceramic powder is 40%-50% by volume, and the content of the organic binder is 50%-60% by volume; the second component comprises a silane coupling agent, cellulose and an organic solvent; wherein the content of the silane coupling agent is 35%-45% by volume, the content of the cellulose is 35%-45% by volume, and the content of the organic solvent is 10%-30% by volume; the volume ratio of the first component to the second component is (1-3): 1. By improving the ceramic slurry, the problem that gaps are prone to occurring between lines/layers of the ceramic part in the printing link, so that the compactness of the part is increased is solved, and the ceramic slurry has the advantages of being wide in application range, low in cost and capable of being easily used for machining the ceramic part in a complex shape.
本发明提供了一种3D打印用陶瓷浆料、陶瓷零件及其制备方法，属于3D打印技术领域。所述陶瓷浆料包括第一组分及第二组分；所述第一组分包括陶瓷粉末以及有机粘结剂；其中，所述陶瓷粉末的含量为40体积％～50体积％，所述有机粘结剂的含量为50体积％～60体积％；所述第二组份包括硅烷偶联剂、纤维素以及有机溶剂；其中，所述硅烷偶联剂的含量为35体积％～45体积％，所述纤维素的含量为35体积％～45体积％，所述有机溶剂的含量为10体积％～30体积％；所述第一组分及第二组分的体积比为(1～3):1。本申请通过改进陶瓷浆料，解决陶瓷零件在打印环节线条/层之间易出现间隙使零件致密度变大的问题，本申请具有适用范围广，成本低，易用于加工复杂形状陶瓷零件的特点。
