Abstract
The present disclosure provides a method of manufacturing a filter, wherein the filter comprises a filter body formed of a porous filtration material and a plastic support structure, the method including performing a first additive manufacturing step to form an initial portion of the support structure; positioning filtration material above or on the initial portion; performing a second additive manufacturing step to form a secondary portion of the support structure such that the filtration material is between the initial and secondary portions. Additionally, the filter body can be enclosed by positioning a first portion of the filtration material to overlay a second portion of the filtration material; and connecting the first portion of the filtration material to the second portion of the filtration material to define a pocket within the filter body, the support structure configured to maintain spacing between the first and second portions of the filtration material.
