Headband

Lowell Makes is 3D printing the NIH approved Face Shield face shield headband.

We are printing out the headbands on our 3D printers using the following settings.

PRINTER SETTINGS

 

Shield

For the face shield PET or PETG film 0.14 mm to 0.5 mm thick can be used. Then if you have access to a LASER cutter or other machine able to cut thin film you can utilize it to quickly cut out the shield. Otherwise you can print out the shield on paper as a template and cut it out then use a 3 hole punch to make the holes.

Note that if you use thinner film it can work, but it may collapse on your face as you walk or move. Ideally use 0.14 mm to 0.5 mm thick film. If you are really desperate you can use transparency film (cellulose acetate), but it is very thin. You can LASER cut two at once and that will fuse them together and make a thicker shield, but it is not ideal.

If you are donating the face shields you may wish to make modifications to the shield dimensions based on your local facilities requirements as some like the shield to be longer or wider.

Note there are two files A and B. A is a single shield template. B is set up to cut out two shields.

Please e-mail [email protected] if you are in the Lowell area and can donate PET or PETG film.

Straps

We are using 3/4″ wide elastic straps from a local company that is donating the material. The elastic is a Thermoplastic Elastomer Compound, which is suitable for skin contact. We cut the strap to 17″ length and then LASER cut three holes on each end of the strap so that the person wearing the face shield can adjust the strap for fit and comfort.

To cut the slits in the strap.

  1. Speed: 10% Power: 100%
  2. Situate the strap left to right on the LASER cutter parallel to the heads direction of travel left to right.
  3. Line up LASER on the left of the strap in the middle of the strap
  4. Hit go
  5. The Laser will move 1/2″ to the right and cut the first slit.

Additional Supplies

  • For packaging to distribute the face shields a 9×12” bag works well. If many shields are going to the same location we suggest packaging all shields in one bag to reduce the number of plastic bags and having the people receiving them assemble the face shields.

If you are using a Prusa design as we were then you can follow along with the video below.
