Sanitization Tests

We understand the concern that PLA can be porous. The Billings Clinic had the same concern, and conducted a set of tests to better understand how porosity effects the potential microbe growth levels on the mask. Their mask was made of PLA filament, created at 25% infill and .15mm layers. After a full day of usage by a local nurse in Billings, MT, they tested the following on standard agar petri dishes for a 72hr bacterial study. Their results showed that swabs taken from masks that were cleaned with bleach or sanitizing wipes resulted in no bacterial growth.
