Freeform 3D Ice Printing (3D‐ICE) at the Micro Scale (Adv. Sci. 27/2022)

3D Ice Printing In article number 2201566, Philip R. LeDuc, O. Burak Ozdoganlar, and co‐workers demonstrate the use of water as a structural material. They present a freeform 3D printing process (3D‐ICE) to rapidly print complex microscale ice structures for applications in biomedical engineering, advanced manufacturing, and even art. The printed ice structures are used as sacrificial template for reverse molding. [Image: see text]
