3D-printed nanofibrous ceramics enables better structural control than electrospinning

Sophia Chen interviews Matt Dickerson of the Air Force Research Laboratory about manufacturing nanofibrous ceramics with additive methods. The discussion explains how block copolymers direct preceramic polymers into fibers, followed by heating that removes the block polymer and converts the precursor to ceramic. Compared with electrospun mats, printing offers control over component geometry. Ceramic springs illustrate repeated deformation without degrading their mechanical properties, with possible applications in catalysts, batteries and high-temperature components.
