3D printing ceramic preparation method and product thereof
The invention discloses a 3D printing ceramic preparation method and a product thereof. The preparation method comprises the following steps: S1, adding ceramic powder into a mixed solution of a binder and an organic solvent, and uniformly stirring to obtain slurry; S2, subjecting the slurry to extrusion moulding through micro-flow extrusion moulding equipment to obtain a ceramic blank, immediately immersing the printed ceramic blank into an inorganic solution, and rapidly moulding, wherein the organic solvent and the inorganic solution are mutually soluble; S3, after the ceramic blank is cured and hardened, taking out and drying the ceramic blank; S4, removing the binder; and S5, calcining at a high temperature to obtain ceramic. The provided ceramic slurry has good fluidity and stability, and has a proper solid phase content, the printed slurry has excellent shape retention ability, and the ceramic blank prepared by calcination is porous and not easy to crack. The porosity is regulated and controlled according to the ratio of the organic solvent to the ceramic powder, a hierarchical pore structure is realized, and ceramic parts with complex geometrical shapes can be prepared.
本发明公开了一种3D打印陶瓷制备方法及其产品。本发明的一种3D打印陶瓷制备方法，包括如下步骤：S1：将陶瓷粉末加入到粘结剂和有机溶剂的混合溶液中搅拌均匀得浆料；S2：采用微流挤出成形设备将浆料挤出成型，得到陶瓷坯体，将打印出的陶瓷坯体立即浸入到无机溶液中快速成型，所述有机溶剂与所述无机溶液互溶；S3：待陶瓷坯体固化变硬后取出干燥；S4：去除粘结剂；S5：高温煅烧得到陶瓷。本发明提供的陶瓷浆料具有良好的流动性和稳定性，具有适当的固相含量，打印出的浆料具有优良的形状保持能力，煅烧制得的陶瓷坯体多孔且不易开裂；通过有机溶剂和陶瓷粉末的比例调控孔隙率大小，实现多级孔结构，可制备复杂几何形状的陶瓷零件。
