The face shields might be useful, but it took six hours for my printer to do one of the Prusia ones. Definitely not a substitute for mass production. As for N95 and similar, please read the warning below:

I don’t want to be a Debbie Downer, but face guards like this are not the biggest need. I have a guy in my town making these out of lacrosse helmets which is great, and he’s getting a lot of likes on Facebook, but… I’m a primary care provider and we need disposable equipment: N95 masks (I have 3 that I cycle throughout the week and will probably eventually get me sick), gowns, gloves, purple tops, hand sanitizer.

I’ve seen a bunch of uplifting news pieces about 3d printed PPE, and I’m a bit confused about it. Printing frames is one thing, but where are the clear shields and proper filter media coming from?

Dunno. This link contains info on supposedly tested improvised PPE using facial tissue, paper towels, and clear file covers - not exactly what people are working on with 3D printing, but related.

Thanks @garethb2, this helps! I just dropped off 33 face shields (a remix of the Prusa RC2 design) I made to a local volunteer organization (https://www.doctorsmakinghousecalls.com/) here in North Carolina. I have the materials for another 40 or so, but I’m looking for somewhere that needs/wants them.
We have a great local organizer at NCSU (https://www.mae.ncsu.edu/blog/2020/03/23/nc-state-covid-19-response-efforts/) who coordinated several local makers in the area to get a total of about 130 face shields made ASAP, which DUMC said their staff of 200+ volunteers had immediate need for. From what I’ve observed, hospitals and similar “establishment” medical providers seem more hesitant to accept/use DIY items provided by the local community.

more PPE self-manufacturing instructions, resources and efforts at http://www.makeppe.net/
includes more than just 3D printing: patterns for masks, disposable gowns, PS-1 suits, isolation gowns for patients

This is ridiculous. We can not continue without the ability to make our own devices at industrial scale.

Did someone say “calls to arms”?

The project I’ve been working on uses specially modified overhead projector sheets, with holes punched to attach to the headpiece (which includes loops to attach the straps of the N95 mask worn underneath).
The stl file just barely fits on my printer bed, and takes about 2 1/2 hours to print just one. I’ve made 5 today.
I think the idea is that wearing these face shields provides that level of protection to cover the mask and allow you to keep using them longer. (shrug)
And today I learned that GitHub renders STL files in a 3D viewer. Awesome.
Also, thanks for explaining about the overhead projector sheets.
