| Abstract Scope |
In response to the ongoing COVID-19 crisis, the development of a reusable and self-sterilizing 3D-printed N95 respirator filter is crucial in limiting the spread of the virus while masks are in short supply. Currently, 3D binder-jet printed metal filters are considered as an alternative to surgical masks due to antimicrobial properties present in some metals and intentional porosity introduced during the printing process can be fine-tuned through printing and sintering parameters. Micro computed X-ray tomography (microCT) was used to characterize porosity, tortuosity, and density of 3D binder-jet printed metal filters to compare sintering temperature, time, and material at the microstructural level. 3D modelling was also performed using meshes created from microCT scans to assess pressure drop and flow characteristics of 3D-printed filters. Our work shows that microCT is a powerful tool in non-destructive characterization and simulation of 3D-printed filters and that measurements can be performed quickly and accurately. |
