Abstract: A monolithic open cell structure apparatus including an open cell structure housing including a first side, a second side opposite the first side, a first opening located at the first side, and a second opening located opposite the first opening at a second side. The monolithic open cell structure apparatus also including a filtration portion extending from the first side to the second side within the open cell structure housing. The monolithic open cell structure apparatus further including a retaining partition that at least partially encloses the filtration portion within the open cell structure housing. The monolithic open cell structure apparatus is a single piece including a unitary structure.

Abstract: A method of manufacturing a pump inlet housing and filter for a pump assembly, wherein the pump inlet housing and filter are monolithic, the method has the steps of: defining a pump inlet housing as a housing tubular shape with an inlet aperture boundary at a housing top end, and an outlet aperture boundary at a housing bottom end; defining a lattice filter between the inlet and outlet aperture boundaries; and performing an additive manufacturing (AM) process to additively manufacture the pump inlet housing and the lattice filter such that the lattice filter is integral with the pump inlet housing.
