Acton 3D PPE: Eggert Design Face Shield Version 3 Update April 4th
Hello and thank you for joining our effort to provide desperately needed PPE for our local medical community. The files that you need are at the bottom of this page. You can print 1, 3 or 4 visors at time depending on the size of your print bed.
We have decided to redirect our efforts to a new design. This design was created by Jon Eggert (on our team) in consultation with Amy Churchill M.D. and her colleagues at Acton Medical. This design is faster to print, faster to assemble, and has the same type of forehead protection as the Budmen. Since we want to pump out as many as we can, switching now will allow us to meet an ever increasing demand.
The plastic shields that attach to the visors are being laser cut and can fit both the Budmen Design and the Eggert Design. We are still building and supporting Budmen designs, so if you have some on your printer, please contribute..
Technical notes from Jon Eggert to get your printers going.
“Attached are the files for printing either one or up to 3 at a time. We have the other materials needed to finish assembling the face shields, so please focus on the printing and we’ll take care of the rest.
PLA filament is recommended and the following settings will help shorten the print time:
- Make sure your bed is level and cleaned with 90% isopropyl alcohol to help ensure good adhesion
- First layer height: 0.3mm
- First layer width 250% - helps ensure there are no gaps in the drip shield
- Layer height: 0.3 or 0.35 if your printer can handle it
- Perimeters: 2 (or 0.8mm)
- Top and bottom solid layers: 2 (or 0.8mm)
- Support: None
- Infill: 10% grid
- Adhesion: None. Disable raft or print times will suffer. These parts bend, so they’re easily removed from the bed.
- Nozzle temperature: Increase by 10%. I print PLA at 225C when printing 0.35mm layers
- Part cooling fan: Always on after the third layer. Run between 50 and 80% fan speed”
You can feel free to get started printing these plastic visors:

| eggert_shield_visor_v3.3-3up.stl |
| eggert_shield_visor_v3.3-4up.stl |
Do not worry about any element of the design other than the visor. We have sourced the padding, elastic, and plastic shields. Ask if you have questions.
