||Additive manufacturing (AM) of ceramics and ceramic composites poses some unique opportunities but also challenges compared to polymers and metals. Process-induced part warping and cracking and less than desired properties cannot be fully controlled. In addition, the properties of the ceramic and ceramic composite parts exhibit a wide variability because of undesired flaws or large porosity, thereby adding great difficulties in producing consistently high-quality components with minimal experimental trials and errors. This symposium will present experimental and modeling work lead to basic understanding of unique aspects in additive manufacturing processes of ceramics and ceramic composites. New processing methods, numerical modeling and uncertainty characterization are particularly encouraged. Research in a broad range of ceramic additive manufacturing processes, such as direct inkjet printing, stereolithography, laminated object manufacturing, selective laser sintering, selective laser melting, and laser net engineered shaping, are sought.
Topics of this symposium will include, but not limited to:
• Ceramic powder preparation and characterization for 3D printing
• Preprocessing and postprocessing methods, e.g., preheating, vibration, sintering, and heat treatment
• Densification and porosity formation
• Solidification and microstructure evolution
• Warping and cracking issues
• Uncertainty characterization, grain boundary and interphase studies
• In-situ monitoring and ex-situ characterization of additively manufactured ceramics and ceramic composites
• Numerical modeling of ceramic AM processes, e.g., multi-scale and multi-physics modeling methods
• Multi-material additive manufacturing, e.g., ceramic-metal composites, ceramic matrix composites, and functionally graded ceramics
• Additive manufacturing of functional ceramics and ceramic composites
