Reusable and self-sterilizing 3D-printed porous metal structures seek the potential to become a reliable and sustainable source of filtration, not only in emergency situations such as during the COVID-19 pandemic through usage of N95 mask filters, but also as air filters in HVAC systems. In order to quantify important microstructural characteristics of these filters, the 3D pore networks were characterized using micro X-ray computed tomography (MicroCT), and pressure drop and particle filtration was tested and compared to different metal powders and post-processing heat treatment conditions. Additionally, 2D cross-section image sequences were considered to predict filtration characteristics and pressure drop. It is seen that anisotropic permeability provides the capability for further filtration tailoring as elucidated through porosity characterization. In this talk, we discuss how processing parameters affect the 3D microstructure and filtration characteristics for subsequent sets of starting powders.
