Abstract:
This paper presents a study on fabricating an ultra-high-temperature compact heat exchanger (CHE) using an extrusion-based ceramic additive manufacturing (AM) system. An aqueous paste composed of a ZrB₂-SiC (70/30 by volume) ceramic powder mixture was used as the feed material in the Ceramic On-Demand Extrusion (CODE) process, which has been developed for the fabrication of dense ceramic components. The CHE features microchannels with a diameter of 500 µm, representing fine features that require high-resolution printing. This work provides an in-depth study of the fabrication process for the successful printing and post-processing of CHEs with fine features using extrusion-based ceramic AM. The paper reports on the mechanical properties, material shrinkage, the quality, and performance of the printed microchannels, which have potential applications in aero-engines, microturbines, and high-efficiency power generation systems.
