Additive Manufacturing by Ceramic On-Demand Extrusion (CODE))

Abstract:

Ceramics are important engineering materials due to their unique properties such as high hardness, high-temperature resistance, and high-corrosion resistance. Additive manufacturing (AM) of ceramic material is difficult and challenging because of the high melting temperature and flaw-sensitive nature of ceramics. This talk will provide an overview of an extrusion-based AM process, called Ceramic On-Demand Extrusion (CODE), which was developed in recent years at Missouri S&T. Included in the presentation are the process concept, the developed CODE system, part and sacrificial materials, feedstock preparation, part fabrication, post processing, sample parts, and characterization of part accuracy and properties.
