Abstract
Additively manufactured ceramic filters are disclosed. A plurality of pores, each having a uniform geometry, are arranged between an inlet surface and an outlet surface of a single unit of ceramic such that the plurality of pores change in size uniformly from the inlet surface to the outlet surface. The pores are respectively interconnected, and the size, shape, orientation, and/or interconnection of the pores are chosen to provide hydrodynamic features that provide effective filtration for a given liquid and contamination. The pores are additively manufactured with optimized precision.
