Protective Face Shield

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

About this project

This design was created by the Swedish company 3DVerkstan. Their design is unique because it takes into account the difference in household hole-puncher that exists between countries (Sweden, Europe and North America)

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 the global economy. The Maker Community has committed to enacting Plan C: filling in the gap with a global network of independent DIY fabricators.

Since the medical community currently (2020-03-20) has a urgent need for protective visors and other PPE for our heroes that spends their days battling COVID-19, myself and my co-workers at 3DVerkstan have spent a lot of time during the past few days designing a printable visor.

This in a WORK IN PROGRESS, and might get multiple revisions during the coming days/weeks, but this first released version is the first one on its way to be tried out by a local hospital.

The plastic shield can be made out of any semi-stiff plastic sheet between 0.1 and 1mm, including overhead film, cover sheets for binding machines etc, as long as it is available in a suitable format.

There currently are 3 different versions. One for SWEDEN, one for EUROPE and one for NORTH AMERICA.

For information about the different versions:

If you need it to sit tighter on your head or if you are leaning over patients a lot and worry about it falling off, a simple rubber band can be put over the two hooks in the back.

For help with print settings:

You need approx a 210x210mm build area to print two at a time, and about 160x190mm if you are OK with only doing one at a time.

The 3MF file shows how you can put 3 of these on a single Ultimaker S5 print bed and print them in 21 minutes per piece with a 0.8 mm nozzle.

Materials and methods

A4 sheet of transparent plastic (~0.2mm PET recommended)

Hole punch

3D Printer

A rigid filament

A rubber band (if desired)
