Ceramic printing piece as well as preparation method and application thereof
The invention provides a ceramic printing piece and a preparation method and application thereof, and relates to the technical field of 3D printing, and the preparation method of the ceramic printing piece comprises the following steps: a ceramic printing biscuit is subjected to multiple times of treatment with a self-constriction solution, and then degreasing and sintering are performed; the self-constriction solution is at least one of a PVA solution, gel and a hydroxypropyl methyl cellulose solution; the treatment comprises infiltration and drying. A ceramic printing biscuit prepared by adopting a binder jet printing method is subjected to infiltration treatment in a self-constriction solution, the self-constriction solution is infiltrated into the ceramic printing biscuit in the infiltration treatment process, drying is performed after infiltration is completed, and in the drying process, molecular chains in the self-constriction solution contract to generate uniform tensile stress, so that the self-constriction ceramic printing biscuit is formed. The powder spacing in the ceramic printing biscuit is reduced, so that the stacking density of the powder is improved, and the biscuit with high initial strength is formed along with the bonding effect of the binder in the ceramic printing biscuit.
本申请提供了一种陶瓷打印件及其制备方法与应用，涉及3D打印技术领域，该陶瓷打印件的制备方法，包括以下步骤：将陶瓷打印素坯采用自收缩溶液进行若干次处理后、脱脂和烧结；所述自收缩溶液为PVA溶液、凝胶和羟丙基甲基纤维素溶液中的至少一种；所述处理包括浸渗和烘干。本申请将采用粘结剂喷射打印方法制备的陶瓷打印素坯在自收缩溶液中进行浸渗处理，在浸渗处理过程中自收缩液渗入陶瓷打印素坯中，浸渗完成后烘干，在烘干过程中，自收缩溶液中分子链收缩产生均匀的拉应力，使陶瓷打印素坯中粉体间距减小，从而提高了粉体的堆积密度，伴随着陶瓷打印素坯中粘结剂的粘结作用，形成初始强度高的素坯。
