Integration of ceramic membrane through 3D printing technology

In this paper, 3D printing technology was being presented for its compatibility with ceramic materials due to its competitive process in terms of cost and speed, especially for the small quantities production. There were four types of ceramic membrane samples used in this study, which differ in thei...
