During the last few decades, additive manufacturing became more popular in the biomedical field because of the ability to create complex shapes and porous or semiporous geometries without extra steps in the production process. An increasing number of printed metal and polymer products are well-established in the market, and quite a few printed ceramic and composite products are gaining interest as well.

Stereolithography is one of the most used additive manufacturing techniques for ceramic materials. Based on selectively photopolymerized ceramic-loaded slurries, this technology allows manufacturers to obtain highly dense final parts (around 99%), as well as good shape accuracy, with a lateral resolution of around 20–30 µm.
