Ceramic photocuring additive manufacturing method
The invention discloses a ceramic photocuring additive manufacturing method which comprises the following steps: preparing a dispersing agent, photosensitive resin, a photoinitiator and an anti-settling agent according to a design ratio, stirring for the first time to obtain a premixed solution, adding nano ceramic powder into the premixed solution, and stirring for the second time to obtain ceramic slurry; the ceramic slurry is subjected to photocuring printing through photocuring equipment applying a temperature field, and a photocured blank is obtained; sequentially degreasing and sintering the light-cured green body to obtain a ceramic part; during photocuring printing, the temperature range of the applied temperature field is 30-80 DEG C. The temperature field is introduced in ceramic photocuring additive manufacturing for the first time, the kinetic energy of resin macromolecules can be increased by increasing the temperature, the flowability of the macromolecules is improved, the surface tension of ceramic slurry is reduced, and the thermal conductivity of the ceramic slurry is improved. Therefore, the viscosity of the ceramic slurry is reduced, the solid content of the ceramic slurry is improved, and finally prepared ceramic parts have high precision and excellent mechanical properties and physical properties.
本发明公开了一种陶瓷的光固化增材制造方法，按设计比例配取分散剂，光敏树脂，光引发剂、防沉剂进行第一次搅拌获得预混液，预混液中加入纳米陶瓷粉末，第二次搅拌获得陶瓷浆料，再将陶瓷浆料通过施加温度场的光固化设备进行光固化打印，即获得光固化坯体；光固化坯体依次进行脱脂、烧结即可得到陶瓷零件；所述光固化打印时，施加温度场的温度范围为30‑80℃，本发明首创的在陶瓷光固化增材制造中引入温度场，通过温度的提高有利于增加树脂高分子的动能，提高了高分子的流动性，并降低陶瓷浆料的表面张力，从而使得陶瓷浆料的粘度降低和固含量的提高，最终所制得陶瓷零件的具有高的精度以及优异的力学性能、物理性能。
