Photopolymerization Technologies for Ceramics and Their Applications

Because of the excellent properties in hardness, strength, temperature resistance and corrosion resistance, etc., ceramic materials are widely used in various fields such as aerospace, biomedical and so on. However, it is still a vital challenge for the manufacturing of ceramics with complex structures applied in the above fields. Additive manufacturing (AM) technology obtains objects by stacking materials layer by layer, which has significant advantages compared with traditional forming methods in manufacturing complex ceramics. Among numerous ceramic AM technologies, ceramic photopolymerization technologies have received extensive attention due to the ideal fabrication quality. Based on the introduction of the principles and characteristics of two mainstream ceramic photopolymerization technologies:stereolithography (SL) and digital light processing (DLP), their research status, applications and existing problems are introduced and analyzed. In the end, a summary and prospect of the ceramic photopolymerization technologies are put forward.
