COVID-19 Evaluating Filtration Efficiency of AM Respirators

Project Overview

There has been a great effort among scientists and engineers to design 3D printed face masks or other alternatives for N95 face masks; however, scientific evaluation is needed to validate their efficacy. Several masks from the leading open-source designs have been 3D printed and delivered to Dr. Linsey Marr's lab for testing. Masks were printed using multiple additive manufacturing processes and materials, including: desktop fused deposition modeling (ABS, PLA), industrial fused deposition modeling (ULTEM), and industrial selective laser sintering (nylon).
