From MIT’s Technology Review: A new way of printing and folding ceramic and metal lattices into miniature structures could lead to novel lightweight engineering structures. The technique involves making latticed sheets from ceramic ink, then folding and heating these sheets to create intricate shapes. The method could be used to make lightweight parts for aerospace applications, complex scaffolds for tissue engineering, and filters and catalysts for industrial chemical production.
“We can make complex, three-dimensional shapes that can’t be made in other ways,” says Jennifer Lewis, director of the Materials Research Laboratory at the University of Illinois at Urbana-Champaign. Lewis developed the technique with Illinois researcher Bok Ahn and David Dunand, a professor of materials science at Northwestern University. The researchers say it fills a need for a way to fabricate complex structures on the centimeter scale–too small for conventional molding or machining, and too big for lithography or similar techniques.
