Compared to metals and polymers, the poor processability of ceramic materials limits their use in industrial applications, despite their excellent properties. Three-dimensional (3D) printing methods can increase the processing flexibility of ceramic materials. Here, we report inkjet-based 3D printing process with different ceramic compositions. Ultraviolet (UV) curable ceramic ink was synthesized from a mixture of ceramic pigments, UV curable monomer, dispersant, and photoinitiator. The rheological properties and jetting behavior of ceramic ink were optimized. The influences of the photoinitiator and contact angle on the additive printing behavior were also investigated in detail. Finally, the 3D objects which consist of multiple ceramic materials and compositional gradients were successfully formed using inkjet printing.

与金属和聚合物相比，尽管陶瓷材料具有出色的性能，但加工性差，限制了它们在工业应用中的使用。三维（3D）打印方法可以提高陶瓷材料的加工灵活性。在这里，我们报告了具有不同陶瓷成分的基于喷墨的3D打印过程。紫外线（UV）固化陶瓷油墨是由陶瓷颜料，紫外线可固化单体，分散剂和光引发剂的混合物合成的。优化了陶瓷油墨的流变性和喷射性能。还详细研究了光引发剂和接触角对添加剂印刷行为的影响。最后，使用喷墨打印成功地形成了由多种陶瓷材料和成分梯度组成的3D对象。
