Face Shields

Check out the information below on how to get started

Why do we need face shields?

Patients with COVID-19 experience significant respiratory issues, resulting in coughing. Virus particles are easily spread in the fluids expelled from the patient during episodes of coughing. The face shield is an additional barrier between the healthcare worker and the patient and reduces the risk of viral transmission via airborne droplets.

 

What considerations should I have in mind when getting started with making face shields?

  • If you can, please segregate the 3D printer that you will be using in your space away from people, pets, bathrooms, or food preparation surfaces.
  • There is still debate about how long the virus survives on hard industrial surfaces, but it is currently estimated that COVID-19 can live on hard industrial surfaces (metal, plastic, and glass) for up to 3 days. If you have access to sanitizing solutions, including diluted bleach, 70% alcohol solution, or products like Star-San or Odo-Ban, please disinfect your tools and equipment before and after each item is made. You can also let packed items sit for 3 days before distributing, as another mechanism to reduce the risk of transmission.
  • Medical-Grade PETG is the preferred filament. If you decide to use another filament, please be aware of the following as it relates to your ability to sanitize the filament.
  • If the machine is clean, the plastic is heated up enough to be considered clean once the print is finished.
  • Do not attempt to sterilize the finished part; just drop in a clear bag with gloves or tongs and set aside.
  • Many sterilization solutions will damage PLA, and off-the-shelf isopropyl alcohol is not concentrated enough to clean the parts.
  • No latex should be used in designs for clinical settings – do not use an elastic band in your design!

What projects can I get involved with to make Face Shields?

Project Name: COVID19 Medical Face Shield (University of Wisconsin, V1)

This design matches current clinical face shield designs and is strongly recommended as a first choice

Specialized Equipment (Recommended): Laser cutter or steel rule die, a stapler, a shear and a heat sealer.

Alternative Equipment for makers at home: Scissors, X-Acto, stapler and Ziploc bags.

Required modifications: Non-latex elastic band
Recommended modifications: Non-porous foam

Notes: Single use only, though disinfection of the plastic is possible with “Oxyvarin” Disinfectant (for McMAster Carr sourced PET, other brands may require different disinfectant)

Project Name: Prusa Protective Face Shield (RC3)

Specialized Equipment Required: 3D Printer
Additional Equipment: Laser cutter or shear/scissors, hole puncher

Notes:
-Open-top design (*this must be mentioned when reaching out to hospitals)
-Not OSCMS approved due to open-top, but medical reviewers have noted it should still be acceptable for certain clinical and hospital settings.

Update:  A variant of RC2 with a closed top has been designed.  Consult with your intended recipient as to best design to use.

Project Name: John’s Hopkins Health System Face Shield

Specialized Equipment Required: None

Notes:
-BOM quantities are for a large batch but can be scaled down when sourcing supplies
-Polycarbonate sheet can be sourced by other vendors if it meets the same specs
