Making Face Shields
There are three main Face Shield designs being fabricated in Illinois right now-- the NIH-Approved Shield, the Swedish Face Shield, and the Solin Face Shield. The Solin design can be made entirely on a laser cutter, and the other two are fabricated with 3D printers and then a clear face shield made of PETG plastic (which can be sanitized without clouding) is fastened to the headband. You can make any piece of these face shields and contribute to the effort. You do NOT need to be able to fully assemble the face shields. Even cutting and fastening elastic is helpful. Read on for more details.
Solin Flatpack face shield
This design is made entirely on a laser cutter out of a single sheet of plastic, including the adjustable headband. We currently have over 70,000 of these in production.
Both Version 8 and Version 9 are out in the wild with Version 9 being the design currently being produced.
We are currently primarily producing the NIH-Approved face shield model.
The STL files for the NIH-Approved Shield model are here. Mark your bag of donations with the name of the model and the material used, such as "10 NIH-Approved Face Shields, made with PLA". You do NOT need to be able to also fabricate the clear piece which goes on the front.
The so-called "Swedish" Face Shield, developed for Swedish Covenant Hospital in Chicago by the popular Swedish Facebook group does not have NIH approval yet but is being accepted by public health agencies in Chicago. It takes about one hour to print; low resolution is recommended to achieve faster build times.
Here is a photo of the Swedish face shield model:
The STL files for the Swedish face shield are here. Note that there is a "right way up" when placing the part on the print bed if preparing the file yourself for 3D printing. PLA and ABS are both considered acceptable materials to build with. Mark your bag of donations with the name of the model and the material used, such as "10 Swedish Face Shields, made with PLA".

Currently only PETG is recommended as the clear material for the face shields, although groups are also using clear PVC and other materials. Some materials, such as acetate, cloud up when cleaned and sanitized, making them unusable. Mark your bag of donations with the name of the model and the material used, such as "10 Solin Face Shields, made with 30 mil PETG". For information on where to donate in Illinois, click here.
The clear shield can either be laser cut or, using a simple hole puncher, 3-hole punched to fit on the Swedish and NIH-approved models.
