Preparation method of high-adhesion ceramic slurry for DLP photocuring 3D printing
The invention relates to the technical field of ceramic 3D printing, in particular to a preparation method of high-adhesion ceramic slurry for DLP photocuring 3D printing, which comprises the following steps: proportionally preparing UV photocuring monomers containing large-volume side chains or ethyoxyl groups into a UV photocuring premixed solution, and uniformly stirring; a dispersing agent is added into the UV photocuring premixed liquid, then ceramic powder is added, and ceramic slurry is obtained; carrying out ball milling on the ceramic slurry; and carrying out vacuum defoaming on the ball-milled ceramic slurry. According to the preparation method, by adding the UV photocuring monomer containing a large-volume side chain or an ethyoxyl group, the shrinkage rate in the photocuring process is reduced, the adhesion performance of the ceramic slurry to a printing platform base material in the DLP photocuring 3D printing process is improved, and the printing stability and efficiency are greatly improved; the printing success rate is increased by 80% or above compared with that of a traditional UV photocuring slurry system, and application and popularization of the DLP ceramic photocuring 3D printing technology are promoted.
本发明涉及陶瓷3D打印技术领域，具体涉及一种用于DLP光固化3D打印的高附着性能陶瓷浆料的制备方法，包括如下步骤：将含有大体积侧链或乙氧基团的UV光固化单体按比例配置成UV光固化预混液，搅拌均匀；向UV光固化预混液中加入分散剂，随后加入陶瓷粉体，获得陶瓷浆料；将陶瓷浆料进行球磨；将球磨后的陶瓷浆料进行真空除泡。本发明的制备方法，通过加入含有大体积侧链或乙氧基团的UV光固化单体，降低光固化过程中的收缩率，提高了DLP光固化3D打印过程中陶瓷浆料对打印平台基材的附着性能，极大地提高了打印稳定性和效率，打印成功率较传统UV光固化浆料体系提高80％以上，促进DLP陶瓷光固化3D打印技术的应用和推广。
