Protective Face Shield

Protective Face Shield - open-source assistive technology prototype by the Coronavirus (COVID-19) community

About this project

This is the third iteration of the face shield prototype developed by Prusa Research. The design has two types of visors that can be utilized. This prototype has undergone two rounds of verification with the Czech Ministry of Health. Read more about the mask specs and development history under resources.

The challenge

Creating a protective face shield that is quick to print, easy to assemble and that can be scaled to be manufactured in large quantities.

Who it helps

Due to COVID19, Medical facilities worldwide are facing a dire shortage of face shields, N95 masks, and other personal protective equipment. Face Shields are not a replacement for N95 masks, however they do act as a protective physical barrier for healthcare workers's faces when dealing with patients' bodily fluids. Many conventional manufacturers have suspended production to follow government-mandated social distancing or run into supply chain issues due to the disruption in thre global econonmy. The Maker Community has committed to enacting Plan C: filling in the gap with an global network of independent DIY fabricators.

How it works

Manufacturing Specs

RC-3 version is the relevant design.

Change log from RC-2:

Removed hexagonal holes for faster printing speeds

With faster printing we use on our farm, some pieces had sharp points and based on testing, the venting is not needed as much

Several optimizations for stack printing

New print files with 4 headbands stacked on top of each other

Stacking headbands is a great idea by the community, especially useful for overnight printing

Developer History

The Prusa Protective Face Shield was developed by Prusa Printing in under three days and sent to 4700 healthcare workers in the Czech Republic for no cost.
