3D printing gradient ceramic core and preparation method thereof
The invention discloses a 3D printing gradient ceramic core which is composed of the following components in percentage by mass: 90%-94% of printing ceramic beads, 1%-5% of a binder, 0.5%-5% of a lubricating dispersant and 0.5%-5% of a two-phase coupling agent, totaling 100%. The invention further discloses a preparation method of the 3D printing gradient ceramic core. The preparation method comprises the following steps: step 1, preparing printing ceramic beads; step 2, preparing a ceramic core blank through laser scanning; and step 3, in the ceramic core blank, the part, bonded or sintered by the laser, of the printed ceramic bead serves as a main body structure, the other printed ceramic beads serve as a supporting structure, and after printing is finished, the ceramic beads which are not bonded and cured are removed so that the ceramic core is obtained. By means of the preparation method, the ceramic core with the light and porous interior can be obtained, the core removal workloadis reduced, and the core removal efficiency is improved.
本发明公开了一种3D打印梯度陶瓷型芯，按照质量百分比由以下组分组成，打印陶瓷珠粒90％‑94％、粘结剂1％‑5％、润滑分散剂0.5％‑5％、两相偶联剂0.5％‑5％，合计100％。本发明还公开了一种3D打印梯度陶瓷型芯的制备方法，步骤包括：步骤1、制备打印陶瓷珠粒；步骤2、激光扫描制备陶瓷型芯胚体；步骤3、上述陶瓷型芯胚体中，打印陶瓷珠粒被激光粘结或烧结的部分作为主体结构，其余打印陶瓷珠粒作为支撑结构，打印结束后，再去除没有被粘结固化的陶瓷珠粒，即成。本发明的制备方法，可以获得内部轻质多孔的陶瓷型芯，减少了脱芯工作量，提高了脱芯效率。
