I don't know if apple came up with the simple design, but it seems that you could make that with any plastic bottle and a lace.

What is the point of 3d printing something that clearly needs to be mass-produced in great quantities? Maybe it "feels good", but it's just too slow. I'm honestly not sure why people don't just use plastic food wrap as a cheap improvised alternative for face shields. It's lightweight, readily available, disposable, fits over any attire and does not restrict visibility.
These kinds of parts can actually be mass produced. You could probably make 3500 face shields in less than a week with 10 printers. The mass produced Prusa i3 printers actually use quite a few 3D printed parts, and they made over a hundred thousand.
There's just no comparing 3d printing with the correct manufacturing equipment. This machine can probably produce hundreds of face shields per minute (wait until the end of the video for full speed):

I was hoping everyone in the US might be able to buy one. Ideally, they'd be cheap enough for municipalities to buy and distribute.
Woofie11 expresses hope that everyone should be able to have a shield, not just health care workers first and people here down vote them? What's so wrong with that? Do you not believe that yes, everyone should be able to have protective equipment not just health care workers? In what kind of a country do we live where we have to ration health care supplies (a basic one at that -- it's literally clear plastic) to only…

> 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.

Mostly time given current priorities -- given that we've spent 100000x the materials and money buying every kind of disposable plastic crap every year for no reason at all...

> 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.
Re: Apple Faceshield
#436The Czech 3D Printer company Prusa has been on it for a while: https://www.prusa3d.com/covid19/ and they have been open-sourcing the design. You can print it on a 3D printer. Based on that design (and others) makers in Germany have started organizing, so that people can either request shields or supply shields. Organized on Slack and into local distribution hubs. We hace started sharing supplies and even got discount…
This design seems pretty odd to me. You already have to have a machine that cuts thin sheet plastic to make the transparent shield part, right? The actual headband is then just another small piece of plastic sheet in Apple's (and others) designs. Seems to me that adding in a 3d printer can only slow things down, since it would be much faster to simply cut the headband with the same equipment that is cutting the shield.

Wasn't even told that about those things in HS chemistry in my time in my country, not sure why - considered too dangerous knowledge by educators? Only found out about it on 4chan and gasped on how easily we could have accidentally injured ourselves while cleaning our dorm bathroom.
I learned about it through The Anarchist Cookbook. They don't teach you in high school not to transport gasoline in a styrofoam container.
They don't teach you how organic solvents often dissolve polar materials such as various polymers? I'm really becoming befuddled here, what do they teach then?

The harm right now is that there's not even enough PPE for hospitals, so anyone buying a face shield for themselves, if that were possible, would keep a face shields from going to a health worker who needs it more. A couple months from now, when pressure on the healthcare system is lower and manufacturing capacity is ramped up? Sure, I'm all for it.
Based on a number of reports I've read about the N95 market, there seems to be plenty of PPE available domestically, but it's all being sold to foreign buyers because the government refuses to institute export controls.

> Touching one's mask is infinitely better than the alternative of touching one's face That depends entirely on if there is a viral build up on the outside of the mask. Discouraging people from using N95 masks was specifically to avoid the private hoarding of masks. But discouraging use of other masks (and N95) by the public is because they do not protect you if they are used wrong. When any air passed around a mask,…
> Unfortunately, any help that wearing a mask would offer to the wearer is often countered by the false sense of security that they bring Today's cars are extremely safe. Are you saying that they actually increase accidents because it gives people false sense of security? Should we remove some of the protections, for example the seat belt, because that would make people drive more carefully?
Tesla autopilot crashes are a closer analogy. A seatbelt is (generally) not an improperly used piece of safety equipment, it generates actual security.

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…
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…
> intubation, which is the process of pulling or pushing a tube down a patient's esophagus
Hope not. It's endotracheal intubation. Tubing the gut (accidentally) leads to gastric distention as we ventilate the patient, leads to aspiration, leads to aspiration pneumonia, leads to huge increase in morbidity.
