| Abstract Scope |
Permeability, the rate of fluid flow through a porous medium, depends heavily on pore size, pore shape, pore connectivity and tortuosity. Because clay naturally has low permeability, conventional manufacturing, mixing clay with water, relies on sacrificial additives, like sawdust, which are burned out during firing at 900 C to create flow paths. Conversely, binder jet printing (BJP) generates inherent porosity without these additives.
This study compares the water permeability and hydraulic pore diameters of BJP-fabricated clay filters against conventional sawdust-burnout filters. The goal is to determine if BJP can achieve the precise pore radius required for antimicrobial filtration, which is less than 4 microns according to World Health Organization (WHO), without sacrificial space holders. Ultimately, the findings will identify which manufacturing method offers better filtration efficiency and in case of binder jet printing, greater viability for producing complex geometries for other functional applications. |
