Coronavirus Face Shields
Many of you have expressed interest in helping out with printing face shields for medical facilities. We’re making almost 200 per day here at the HVAMC and three different medical organizations have said they will take as many as we can make. In NYC, one hospital is looking for 25,000 of these.
We would like to thank the NoVo Foundation and Central Hudson Gas & Electric Corporation for donating to this special project.
Thanks to our partners who are contributing to this effort:

MakerBot - for their kind donation of parts to keep our Replicator 2 printers running!
Stl files are available here on our GitHub site. There are two files - one for the headpiece, one for a band in the back.. The dimensions for the headpiece are: 167.34 mm x 136.75 mm x 15.03 mm. The dimensions for the strap are 118.25 mm x 23.00 mm x 1.20 mm. Also available for download is a template for punching holes in an 8.5x11 transparency. A picture of the assembly without the shield is shown below.
We recommend using PLA. Other materials are fine, but PLA is the least expensive and most environmentally friendly 3D printing material. Suggested print settings optimized for speed are at the Github site. These will really push your printer so use them with caution. No raft or supports are needed.
Hygiene and Packaging
It’s really important not to pass along any viral material. Our best guess at the right procedure is to take them right off the build plate (wearing gloves) and put them in ziplock bags. The gallon sized will hold 10 complete sets. If you’re using multiple printers, it’s really helpful to run them in batches. I would minimize the number of people around the printers and everyone should be washing hands/sanitizing regularly. We do not want to make the problem worse.
Shields and Rubber Bands
The best solution we have so far for the shields are transparencies. The best ones are the original write-on kind or the types for laser printers/copiers. Avoid using the old thermal types or the ones for inkjet printers. The holes can be easily made using an adjustable 3-hole punch. You can set it up so you punch two holes on side and then flip it over to punch the other two holes from the other side. It just needs to line up with the Mask Pattern file. We are trying to use 0.005 inch PETG, which we think will be better than transparencies.
For rubber bands, we’ve been using the big bags of 3.5” rubber bands from Staples. Anything around that size is fine.
Option 1: You can send us the 3D printed headpiece at the address below. We’re happy to print the other part and supply the rubbers bands and transparencies.
Option 2: You can assemble the headpiece and band with the rubber bands and distribute them to health care providers, first responders, etc. yourself with the hole-punched transparencies. We do not put the transparency on the headpiece before distribution. Just makes sure that the transparency is easy to attach. These folks are very, very busy.
