Preparation method of 4D printing ceramic and ceramic piece
The invention discloses a ceramic 4D printing method and a ceramic piece, and the ceramic 4D printing method comprises the following steps: respectively preparing a first ceramic slurry and a second ceramic slurry which have different shrinkage rates under the same sintering condition by adopting raw materials comprising ceramic powder and light-cured resin; the first ceramic slurry and the second ceramic slurry are subjected to different slurry alternate printing through a 3D printer, and a green body is prepared; and sintering the green body. In this way, 4D deformation of the whole structure can be achieved through the internal stress generated by the shrinkage rate difference of the first ceramic slurry and the second ceramic slurry in the sintering process; in addition, printing forming is fast, raw materials are simple, operation is convenient, cost is saved, and the 4D printing method is easy to operate and has great application prospects in the aspects of self-assembly, self-repairing or self-induction and the like.
本发明公开了一种陶瓷4D打印方法和陶瓷件，该陶瓷4D打印方法包括：采用包括陶瓷粉体和光固化树脂的原料分别制备在相同烧结条件下收缩率不同的第一陶瓷浆料和第二陶瓷浆料，而后在紫外光照射下，采用第一陶瓷浆料和第二陶瓷浆料通过3D打印机进行不同浆料交替打印，制得坯体；再将坯体进行烧结。通过以上方式，可利用烧结过程中第一陶瓷浆料和第二陶瓷浆料的收缩率差异产生的内应力来实现整体结构的4D变形；并且打印成型快，原料简单，操作方便，节约成本，该4D打印方法操作简单，在自我组装、自我修补或自我感应等方面存在很大的应用前景。
