Description

This device is a general purpose face shield intended for use in the community and is not suitable for use by a healthcare professional or in a healthcare facility or environment, as described in FDA Guidance Enforcement Policy for the Coronavirus Disease (COVID-19) Public Health Emergency. This device has not been tested to assess the out-gassing limits of the material or their corresponding health effects. Minimum Viable Product Face Shield: The goal is to fabricate and get as many Face Shields to hospitals as possible in the least amount of time while still achieving the intended function (Help block bulk aerosol particles from reaching the face). This is achieved two-fold; the face shield design was paired down and optimized as much as physically possible in order to minimize print time on FDM/PJP/FFF type printers, and the part is printed “stacked” to maximize print density in a 24 hour period. Readily available transparency/report cover film with a standard 3-hole punch pattern and rubber bands comprise the other components of the mask. With the included print stacking method, a single printer could produce 60+ frames per day.
