Method for preparing multiphase ceramic by using direct-writing type 3D printing technology
The invention discloses a method for preparing multiphase ceramic by using a direct-writing type 3D printing technology, and belongs to the field of ceramic material additive manufacturing. The invention aims to solve the problem that after the existing ceramic precursor is directly written and printed, the linear shrinkage rate and porosity of a component are high in the pyrolysis process of a green body from a polymer to ceramic, so that the mechanical property is reduced. The method comprises the following steps: 1, weighing; 2, preparing ceramic slurry; 3, 3D printing; and 4, curing and pyrolyzing. By changing the diameter of the needle head, integrated forming of the three-dimensional ceramic component which is complex in shape, different in resolution ratio, low in shrinkage, high in ceramic yield and good in mechanical and dielectric properties can be achieved. The method is used for preparing the multiphase ceramic by using the direct-writing type 3D printing technology.
一种利用直写式3D打印技术制备复相陶瓷的方法，它属于陶瓷材料增材制造领域。本发明要解决现有陶瓷前驱体直写打印后，坯体从聚合物至陶瓷的热解过程存在构件线性收缩率及孔隙率高，导致力学性能下降的问题。方法：一、称取；二、制备陶瓷浆料；三、3D打印；四、固化及热解。本发明通过改变针头直径大小即可实现形状复杂、不同分辨率且低收缩、高陶瓷产率、良好的力学及介电性能的立体陶瓷构件一体化成型。本发明用于利用直写式3D打印技术制备复相陶瓷。
