Penn Health Tech Covid-19 Rapid Response Team - PPE production crowdsourcing: Face-shields

Disclaimer: This information is not provided with any indication that the process is good or better than others. It is a documentation of the process that we established as we scrambled to put a larger group of people to work together during this emergency.

Here you will find our documentation should you wish to produce medical face shields at your institution, including 3D files and all necessary documentation.  You may download, re-use and modify all documents on this page.  The designs (1 listed below, more on the way) provided in this guide have been evaluated by Penn engineers and tested by Penn Medicine providers.  You may adapt this process to print other designs, however you will need to evaluate and test these designs from scratch. 

 

Process components: 

  • Fabrication: Frames (3D-printed), plastic shield (manually / laser-cut)

  • Supply chain:
    • supply: raw materials, tools and equipment
    • transportation: of raw materials, tools and equipment between volunteers, and delivery of finished parts to hospitals
    • quality control and packaging

Fabrication - Design 1

  • 3D-printed frame + plastic sheet
  • Simple design, easy/fast crowdsourced production

Fabrication - Design 2

  • faster construction than 3D printed designs
  • contains no foam or elastics and can easily be disinfected and reused
  • requires laser cutter  and riveters

Delivery supply chain

Coordinating supply, transport of materials, quality assurance and delivery is the most essential part of the process! We were blessed with a team of brilliant and devoted students who worked around the clock to create an efficient process.  Below are all the documents we are using to track activities.

Key Take-Aways, courtesy of our Supply Chain Lead: 

  • Gather 3D printers (schools, makers, designers) and request an expected production rate
  • Set up Quality Control (QC) points to find defective units and count the actual number of shields delivered
  • Contact local hospital and the person responsible for handling donations and cleaning
  • Appoint point contacts for all sub-groups to manage key activities now, but also be responsible for onboarding more volunteers as operations grow
