Benchtop assessment of sealing efficacy and breathability of additively manufactured (AM) face masks

“…Workflows or processes applied to AM face mask designs may help improve the fit to a user’s facial profile. To improve the performance of AM face masks, some designers and users suggest matching the mask to the users via 3D facial scanning [36] , adding foam strips to the face-frame interface [38] , or molding or face-forming [39] the AM frames using methods such as forced hot-air, hot-water, or microwave [2] , [40] , [41] . If done successfully, then it may be reasonable to conceptualize why and how these individualizations, augments, and post-processing routines could improve the fit of the AM masks and reduce aerosol leakage.…”
