Talk Title: Additive Manufacturing of Advanced Ceramics: Technologies, Applications and Opportunities
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. However, through intensive research over the past two decades, significant progress on AM of ceramics has been made. This talk will first review different categories of ceramic AM processes and recent technology advances in each category. Comparisons will be made on the advantages and limitations of each ceramic AM process category in terms of part quality, dimensional accuracy, surface finish, and material flexibility. The practical applications of various ceramic AM processes in relation to the characteristics of each process category will be described. A novel extrusion-based AM process, called Ceramic On-Demand Extrusion (CODE), which was developed in recent years by the seminar speakers research group for fabricating ceramic components with near theoretical density will be presented, including choice of support material and part fabrication with multiple and graded materials. Finally, future research needs and innovation opportunities of ceramic AM will be discussed.
