> I was hoping everyone in the US might be able to buy one. This burst of PPE being produced in mass quantities are and were never meant to go in the hands of the general public (i.e., non healthcare workers), though. The general public does not need to be walking around with a full face shield, that’ll be a waste of materials, time and money, unfortunately.

Given that they probably would cost $1 to $5, and take almost no space to store, it wouldn't be a terrible thing for people to have a few if they want them. How many people have a $20 multi-tool that stays in a drawer somewhere? Or some bags of rice "just in case" that end up getting thrown in the trash after being forgotten about in the cabinet for 5 years? It may not be a terrible thing if some percentage of people…

Regular people should not use non-reusable anything. Just because I can spare $100 doesn’t mean I get to trash the earth with disposable junk. Make reusable/washable masks and then I don’t care if people cover their face or behind with it. Masks do help - for allergies, dust, and other things. I do wear a bandana while running because it helps with allergy. Only because I don’t want to risk another lung issue while also being in risk for covid.

Lack of testing and a laggard&lackluster response by authorities. USA will be one of the hardest hit countries in the world. There's still no stay-at-home order. Trump wants to reduce what little is being done after Easter. That's going to make the situation considerably worse.

All true, but even with stay at home orders, not everyone stays home. Some people are essential workers and have to go to work. Other people go out for exercise, grocery shopping, etc. If those people have protective equipment available it is truly senseless to not wear it given the extreme danger.

Appropriate equipment yes, absolutely. But even doctors and nurses do not wear face shields routinely around hospitals. They are worn when performing particular procedures and circumstances that don’t apply to most situations even in hospitals.

It's not about the money. PPE like face shields are specifically used during procedures that involve significant bodily fluid, like intubation, which is the process of pulling or pushing a tube down a patient's esophagus. Going to to the grocery store does not require a shield. Secondly disposable medical equipment, when used properly within a healthcare environment, is extremely wasteful. For most consumable items u…

Hopefully you are intubating a patient’s trachea and not not the esophagus.

Thank you! I had missed this news, so a link to a support article with no explanation was a little mystifying.

I expected this to be for apple factory workers, surprised to see its being sold to other companies.

These are only used by doctors and nurses when treating patients with open airways at very close range to protect from direct splatters with body fluids. Eg when intubating a patient that’s having explosive coughing fits. They are also part of a complete protective system including a mask, elasticated hair cover, full body wrap aprons and long arm gloves. There is no point using a shield without the rest if the gear because if you are in a situation where you need the shield, you also need the rest as well.

Most medical professionals don’t even wear this full kit routinely in hospitals, let alone when they are out in public, so there’s no need for the public to use them in general working conditions.

I've been making these for a couple weeks now. The clear plastic part is generally sourced using the thick binder/presentation covers that come in 8.75x11.25 inch sheets, precut. The only requirement is a hole punch. Headbands can be any elastic material (I've been using button hole elastic for easy adjustment).

By headband I mean the part that you are 3d printing. Both designs still need an elastic strap.

I'm not actually sure what you're saying, then. Why is the 3d printed version odd if the transparent part is easily sourced without needing a die cutter?

Sure. But for an equal amount of effort, raws and manpower you could get much more out of traditional manufacturing, much quicker. The product is a very simple stamp, with very simple dies with little wasted material. Perfect for traditional production methods. It's great people with machines are contributing to the effort, and empowering/informing individuals to be able to do so as well. But it's just done simpler t…

I don't understand your argument. Those 3D printers exist and can be used. Manufacturing and those printers are not exclusive options.

My "argument" was in response to the parent comment saying 3D Manufacturing can 'scale'. Which it certainly can, just not as simply or efficiently as traditional methods. Especially in this case with such a simple part.

I didn't intend to impinge on the people helping hospitals or people with faceshields now via 3D manufacturing hence the 'It's good...' part. Rather simply comment on scaling up manufacturing methods.

> There is currently a global pandemic afoot that is spread by droplets expelled from people's mouth and nose. Do you have any source on how face shields are an effective tool against atomized covid19 viruses? The general guidance is that facial masks are effective at barring infected people from emitting contaminated particles, but not good at stopping healthy people from having contact with the virus. Therefore why…

I hear mask promoters say the “it’s to protect others from you” line, only to turn around and say “masks are obviously useful, that’s why doctors wear them.” The truth is, mask use is built on incredibly shaky evidence, so it’s no surprise that now face shields will become part of the hype. Both may indeed be useful, but without a clear model of effectiveness, it’s hard to make good assessments.

You seem to conflate so many things here. Doctors wear mulitiple types of masks. Surgical masks (as are recommended for the general public) prevent a doctor from spitting on a patient accidentally (just as they prevent an infected individual from expelling virus laden spit droplets). Surgical masks provide limited (if any) protection from airborne droplets. Rather an N95 masks (with a seal and filter) is used. To make this effective to protect the wearer, goggles must also be worn. The general public does not wear goggles. Further,training on putting on and taking off masks is provided to medical professionals. Face shields protect from yet another class of dangers (splashing of contaminated fluid). The general public has little reason to wear these.

So your argument is that the risk to the average American is low from COVID? Why do we have 300,000 cases then? Why are 1000 people dying a day? That's already 0.1% of the population, and most of them in the past week!

The risk is very high, my wife is a nurse here in the UK and is infected. Fortunately she has light symptoms and a light cough. When I am with her we both wear a face mask, but there is no need for a shield because I’m not intubating her her or at risk of heavy splatter from close range explosive coughing. Again, even doctors in hospitals only wear face shields under specific circumstances, which are situations the g…

I would humbly suggest that doctors very rarely deal with diseases this dangerous (infectiousness + lethality) and that more extreme protection is warranted. As you well know, it is difficult to not catch this thing.

I would much rather overdo my PPE than underdo it. Overdoing it just costs me a little time, underdoing it costs lives and injury.

If you want to see what it takes to have a hospital where no one gets infected, this is instructive. https://youtu.be/9HsGqQCLzLU
