To meet the industry’s growing demand for customized manufacturing, researchers are increasingly interested in processing transparent ceramics using additive manufacturing. Guangran Zhang and Yiquan Wu of Alfred University demonstrated how highly transparent yttrium aluminum garnet ceramics could be fabricated via a lithography-based digital projection method.
