Four-dimensional printing method of polymer derived ceramic material
The invention discloses a four-dimensional printing method of a polymer derived ceramic material, and relates to the technical field of ceramic forming methods. Comprising the following steps: S1, preparing polymer derived ceramic slurry, and printing a green body by adopting a stereolithography 3D printing technology; s2, curing and drying the green body, then changing the green body into a set reconstructed shape through external force, and heating and preserving heat to obtain a green body with the reconstructed shape; s3, after the blank is cooled, the blank is changed into a set temporary shape through external force, the blank is cooled to the room temperature, and the blank in the temporary shape is obtained; s4, heating the green body with the temporary shape to enable the green body to be automatically converted into a reconstructed shape, and performing degreasing and sintering treatment; obtaining a polymer-derived ceramic material; the raw materials of the polymer derived ceramic slurry comprise bisphenol A diglycidyl ester and hexahydromethyl phthalate. In the step S4, the original reconstructed shape can be obtained through heating, mechanical loads do not need to be applied, the forming difficulty is low, and the forming precision is high.
本发明公开了一种聚合物衍生陶瓷材料的四维打印方法，涉及陶瓷成型方法技术领域。包括步骤：S1、制备聚合物衍生陶瓷浆料，采用立体光刻3D打印技术，打印出生坯；S2、将生坯经过固化干燥，之后通过外力将其改变为设定的重构形状，加热保温，获得具有重构形状的坯体；S3、将坯体冷却后，将其通过外力改变为设定的临时形状，并降至室温，获得具有临时形状的坯体；S4、将具有临时形状的坯体加热，使其自动转变为重构形状，经过脱脂、烧结处理后；获得聚合物衍生陶瓷材料；聚合物衍生陶瓷浆料的原料包括双酚A二缩水甘油酯和邻苯二甲酸六氢甲酯。在S4中，通过加热即能获得原本的重构形状，不需要施加机械载荷，成型难度低而精度高。
