1 研究现状
相比于传统的胶态成型（流延、注浆、凝胶注模成型），立体光固成型具有成型精度高，表面质量好的特点，在制备高度复杂陶瓷部件具有独特优势。目前陶瓷立体光固化技术在浆料制备、成型工艺、脱脂、烧结及性能表征方面已经取得重大突破，促进了结构陶瓷在航天航空、医疗植入、电子封装、珠宝首饰等领域的应用与发展。
2 研究难点或瓶颈
首先，高固相含量、低粘度的陶瓷浆料难以制备问题仍是限制光固化技术制备高性能陶瓷部件的关键因素；其次，粉体对紫外光的吸收和散射仍是影响成型精度、成型速度及坯体强度的重要因素之一；最后，脱脂、烧结过程的缺陷形成机制仍不清晰，缺陷与形性控制仍然艰难，特别是大尺寸、复杂结构、多材料集成陶瓷部件的性能调控与净尺寸成型研究仍是空白。
3 展望
在浆料制备上，仍需突破高固含量、低粘度浆料难制备问题，并开发光固化性能好、固化收缩率低、打印坯体机械强度足够的光固化陶瓷浆料。在打印过程中，还需系统分析陶瓷浆料与紫外光的相互作用，探索陶瓷粉体表面特性对紫外光吸收效率的影响，研究浆料中紫外光的耗散规律。此外，打印速度与打印尺寸仍需进一步提高，以提高陶瓷制备的效率。脱脂过程中的开裂、翘曲及各方向收缩不一致问题还有待解决。烧结温度场和应力场的控制技术、陶瓷的后续强化技术，以及控制应发展尺寸精度技术仍需完善。此外，应当开发完善多材料打印设备以及大尺寸陶瓷打印设备，并结合结构设计与工艺优化，实现多材料-多结构-多功能陶瓷部件一体化设计与制备。
