I have rolls of Polypropylene fabric purported to be the stuff N95s are made of. Happy to give you as much as you want if it can work for your filter medium.
Thats really great. If I could get a spool of elastic would that help?I know some of you saw this on my business' FB page, but I'll share here direct as well. I was contacted by a surgical nurse at Denver Health (at first I thought it was UC Health) who asked if I could 3D print N95 masks, as they are rationing them, they only get 1 per day when they are supposed to use a fresh mask between each patient. I tried the design she sent me the link to and it was a horrible design, didn't work at all. I iterated in Solidworks most of that week with that approach, but it needed too much post-printing assembly. Then my nephew sent me a link to a different design that worked great, and I have been making them ever since. Turns out the Jeffco sheriffs are interested as well. I am making them in two sizes, 100% seems to work well for larger faces, and 90% mainly for women. They use a disposable filter material which is as close to N95 as you can get without actually having it certified by NIOSH. Since they're plastic, they can be sanitized and reused over and over. The user has to provide their own straps. I couldn't find any elastic anywhere (Walmart, Michaels, Hobby Lobby are all sold out, and Amazon was a month lead time). You can use shoelaces or similar though.
So far I have made about 100 masks and have been making them non stop for over a week now. I had 6 machines building them, but one is broken now and needs repair. I am donating them at no cost to the hospital. I am also purchasing the filters and donating them as well.

How many yards you need?Yes, 1/4" is what I have been shopping for!
The Israeli team who started the project is currently jumping through all the hoops to get the machine certified to be used on humans in Israel. They just completed an animal trial with a pig and they passed so now they're moving forward to the next stage. Apparently they have great support from the Israeli government and Air Force and every Israeli ambassador around the world is aware of their project and starting to cut red tape. The Israeli Air Force is volunteering planes to transport one or more of their units for evaluation here in the USA or elsewhere.How are these being distributed to those in need?
please stay safe and follow the guidelines.
I guess the buzzword for this type of device is "compassion equipment" vs. "medical equipment"
They are shipping some elastic fedex to me . Would expect I could have you whatever you need early next week.
couple hundred yards or what?
Well considering Alexander Fleming discovered penicillin in 1928 and that the reason the majority of people who died of Spanish Flu a decade before was due to complications from bacteria pneumonia I'd say "technology" is a pretty key difference now. If you're normally healthy and with modern medicine the Spanish Flu is an incomplete comparison of outcomes.I know we are in a lot better situation with technology and medical infrastructure than we were back then

We'll find out if the government's efforts to boost liquidity fail. I think they will eventually, but I could be wrong as so many things have not made any sense for the last 15+ years. 2008 proved that. I don't get it and it bothers me a lot.Weekly initial unemployment insurance claims.
https://www.dol.gov/sites/dolgov/files/OPA/newsreleases/ui-claims/20200592.pdf
3/21/20: 3.059 million
3/28/20: 6.867 million
4/04/20: 6.606 million
That's 16.532 million new filings, which they claim represents 5.1% unemployment. That's true if you say the newly unemployed comes from a pool of potentially 330 million, which is a population of everyone man, woman and child in the U.S. (16.532/330 = 5%).
Just arbitrarily removing those under 18 (22.4% of the U.S.) and over 65 (16% of the U.S.) means the count of those truly available for work is really no higher than 203.5 million, which indicates unemployment in the last 3 weeks has gone up by more like 8.1% (16.532/203.5).
They were claiming around 3.5% unemployment back at the beginning of March. Statistically the government thinks full employment is filling around 161 million jobs.
https://www.bls.gov/news.release/ecopro.nr0.htm
So a 3.5% unemployed rate means they previously used around 166.6 million people to represent the pool of available workers (assuming every job was actually filled) and 5.635 million people were not employed prior to the lockdowns. So there's now 22.17 million unemployed. Thus current real unemployment is probably more like 13.3% (22.17/166.6) at 3 weeks into this implosion.
In that span of 3 weeks it appears 10% of the workforce has lost their job. How many more are in limbo?
https://www.cnn.com/2020/03/17/politics/steven-mnuchin-unemployment-warning-coronavirus/index.html
The president's Treasury man Mnuchin says 20% unemployment. Which probably means the real number of unemployed will be more like double the official numbers, around 55 million of 166.6 of those considered to comprise the workforce. But I suspect a change to the pool of labor is already assumed since 20% of 330 million (everyone who can work will be looking regardless of who you are) is 66 million and so the numbers start to converge.
