Song’s Lab Develops New Technology for 3D Ceramic Printing

ACS Applied Materials & Interfaces

ISE graduate students Li He, Fan Fei, and Wenbo Wang and Prof. Xuan Song have developed a new technique for ceramic 3D printing that reduces the technical challenge of producing parts with overhanging structures.  The new approach, demonstrated in Prof. Song’s lab in the Department of Industrial and Systems Engineering at the University of Iowa, can produce precise ceramic parts that have relatively long, unsupported elements.  The work is described in the most recent issue of ACS Applied Materials & Interfaces 2019 11(20), 18849-18857.

Fabrication results via the SEPS process: (a) a structure with an overhanging ball and cube; (b) a tube with an inner overhanging chamber; (c) a spring structure printed with an upward slope angle; (d) a ball check valve with an inner chamber and a movable ball inside printed without assembly; (e) a heat exchanger with an inner chamber and overhanging hollow pipeline (e1–e3); (f) a combustion chamber with overhanging nozzles (f1–f3); (g) a CAD model of a treelike structure (g1) and the printed treelike structure and its microstructures (g2–g6); (h1, h2) the sintered overhanging tube; (i1, i2) the sintered combustion chamber.
