Photocuring 3D printing ceramic composite material as well as preparation method and application thereof
The invention belongs to the technical field of biological ceramic materials and additive manufacturing, and particularly discloses a photocuring 3D printing ceramic composite material and a preparation method and application thereof. The light-cured 3D printing ceramic composite material is prepared from the following raw materials: basic ceramic powder, light-cured resin, an inorganic toughening agent and an auxiliary agent, the light-cured resin comprises first light-cured resin and second light-cured resin, the refractive index of the first light-cured resin is 1.42-1.52, and the refractive index of the second light-cured resin is 1.60-1.70; the volume ratio of the first light-cured resin to the second light-cured resin is (9: 1)-(2: 8). According to the preparation method disclosed by the invention, the biological ceramic, especially a fine complex pore structure with highly communicated interior, can be prepared through photocuring, the toughness of the biological ceramic implant for craniomaxillofacial is remarkably improved, the fracture toughness can reach 0.769-0.869 MPa.m < 1/2 >, and the bending strength is 6.18-7.84 MPa.
本发明属于生物陶瓷材料及增材制造技术领域，具体公开了一种光固化3D打印陶瓷复合材料及其制备方法与应用。光固化3D打印陶瓷复合材料的制备原料包括基础陶瓷粉料、光固化树脂、无机增韧剂和助剂；光固化树脂包括第一光固化树脂和第二光固化树脂，第一光固化树脂的折射率为1.42‑1.52，第二光固化树脂的折射率为1.60‑1.70；第一光固化树脂和第二光固化树脂的体积比为(9：1)‑(2：8)。本发明可实现光固化制备生物陶瓷尤其是精细的内部高度联通复杂孔隙结构，达到显著提高用于颅颌面生物陶瓷植入物的韧性，断裂韧性可达0.769‑0.869MPa·m1/2，弯曲强度6.18‑7.84MPa。
