| Abstract Scope |
Ceramic 3D printing is unique, involving material extrusion of soft wet clay over slicer defined paths to create a layer-wise part. Unlike fused deposition modeling (FDM), where molten filament solidifies out of extruder, in ceramic 3D printing, a slurry of clay is extruded out of nozzle that begins losing moisture due to exothermic reaction. Diffusion of moisture within printed part and to the surrounding causes drying of part. However, this process of drying is influenced by geometry, print parameters and constituent materials, often leading to non-uniform drying and defects such as delamination, voids, and cracks. This paper presents a numerical model for predicting time-dependent moisture in a ceramic 3D printed part. Physical experiments are used to measure moisture content at different instances of time for geometries with varying complexities. Results of physical experiments are incorporated in the numerical models to predict moisture in part at different times of passive drying. |
