NIH Stratasys Face Shield - COVID entry #8

Happy respiratory therapists with the face shields I'm making

EDIT: 4/7/2020 - Well ... for some reason, tonight, NIH has moved this model to the under review section. The notes are the same and there is no reason listed. I think it might be an error

If you are printing the re-mixed Stratasys face shield on the NIH site here are some tips on the shield & the holes:

NIH Shield project is here - https://3dprint.nih.gov/discover/3dpx-013421

If you don't have laser cutting equipment, or some other cool way to CNC cut the shield material use the file there. The NIH one does not have the logo. I think that's actually better from a cleaning & re-use perspective.

The file on the NIH page has a slight modification to the last hook over the Stratasys shield with the logo that's on the Stratsys Site. This is to make it easier for those of without the laser cutting capabilities, like me.

It's got a small protrusion on the right hook (as you are looking at the front of the visor. The other hooks appear to have a smaller slot for the shield material and the hook seems a tiny bit shorter. This allows a standard three hole desk top punch (U.S.) to be used to punch the holes and the holes are tight enough. Actually still requires a good tug on the last hole.

The shield material should be cut to 8" x 12". Punch the 12" side.

Start putting the shield on by hooking the shield on the left most hook (as you are facing the front of the visor), then the center, then pull it over the last one with the back side protrusion.

My first two dozen plus go to my wife's respiratory care department today. I'll post back with results. She took one visor over the other day and everyone liked the fit. I'm printing with PLA. I'm wondering if it will be more durable than the PETG.

I've got enough stuff on the way for 700 plus of these and maybe 50 of the Budmen shields. Maybe more if I ration the foam. Hopefully I'm taking one hospital off the want list for faceshields.


I started with the Cura built in low resolution settings
Machine - Creality CR10S Pro (about a year old)
I'm printing @ 230C (my machine might be out of calibration)
.3mm layer height
.4mm line width
First layer @ 240C
First layer speed 70 mm/s
First layer flow 150%
Print speed 90 mm/s
Two bottom layers
Four top layers
10% fill EDIT: Switched to 20% fill. Top of the visor is much tighter now. Added ~20 minutes.
Walls - 2 rows
Travel I think is set to 95 or 100, my machine was making funny noises at 145.

I did my own 2 up layout in Cura. Just open two, rotate & reposition the 2nd one so they are back to back. I've got a Creality CR10S Pro so I have plenty of room. Taking ~2:40 to print two.

Good luck everyone! Stay safe. Might be a really interesting week.
