Face Shield

We have designed a fast-printing, lightweight minimal face shield that requires no hole punching or laser cutting or elastic bands.

  • Uses only about 10 grams of plastic
  • Prints in about 20 minutes on a PolyPrinter 229 printer.
  • shield material is relatively readily available 8.5x11 transparency sheets, cut in half with corners trimmed. Scissors are the only tool needed. A paper shear does help.

NOTE: This is till very preliminary. Using a half sheet makes for a shorter than full covering area. We are looking for feedback based on evaluation by actual potential users.

Transparency Film

The clearest one we have found is the Samsill Economy Transparent Printer Paper (.10mm PET) - currently (4/9/2020) unavailable on Amazon


Also, there are MANY face shield designs out on the web! Some are more robust, have larger shields etc. But they are virtually certain to take a longer time to print. You should decide on what to print based on your access to tools, materials, and the options of those who need such devices.


We have made tuned gcode available for immediate use:

ABS: Minimalist Face Shield 229 - Small

Minimalist Face Shield 229 - Medium

Minimalist Face Shield 229 - Large

Minimalist Face Shield 229 - XLarge

Large - for 465dx

Each shield requires 3 clips:

ABS: Face Shield Clips x9 229

Clips x57 for 229

Clips x9 for DX

Clips x57 for DX

Why ABS? What about other materials?

The great majority of our customers use only ABS and presumably only have ABS on hand.

As far as a we know, our go-to ABS filament is fine for both skin contact and for cleaning with alcohol or hygdogen peroxide, though the color may be affected. It may get 10% or so weaker, which I don't think should be an issue. (If you find problems or successes otherwise, please let us know.)

PLA: will probably work fine. More brittle and stiffer. Not sure about disinfecting with alcohol or hydrogen peroxide. Ask for gcode.

Nylons: Nylon filaments require the use of a glue stick to print, and are quite soft and so will not work with our springy design. They might work with other designs but I really would not recommend using Nylons for face shield - we really don't think it's necessary and will slow you down a lot.


If you don't have a PolyPrinter:

NOTE: Wall thickness is 1.05 mm in most places. YOu might want to use an extrusion width of .35mm or .525mm, whichever works better. The Z dimensions are all multiples of .25mm so we suggest using a constant .25mm layer height.
