Default 3D printed face masks

My wife works in the medical field and things are beyond desperate. I saw this:

http://www.wfsb.com/tncms/asset/edit...b-faa13e60145b

A company in this link has the inserts and gives the .STL files needed for the 2 components

https://longliveyoursmile.com/3d-pri...-for-covid-19/

I orders the inserts today and picking up a 3D printer from work to try it. If anyone has access to one, you can certainly help someone on the front lines.

Thanks for your consideration.

Its a great idea, however doing anything in production with a 3D printer unless its very small is almost impossible. Most 3D printers are very slow to say the least. Hopefully they will take the idea and get it into production via vacuum forming or rotomolded

Sorry about the hyperlinks - they should be working now. I agree 3D printing is not efficient when compared to other types of production, but if we can encourage schools, hobbyist, libraries or any other groups that have printers idle, it will have a positive impact on someone. Trust me when I say that. Incidentally, I just read today they are going to limit the amount of testing to those who are very ill because of a lack of PPE. Again, thanks everyone for their consideration!

I can't imagine most 3D printers would be fast enough to make much difference but it can't hurt to try.

I get what the others are saying about speed but I totally see where you’re coming from with this, OP...and I applaud your efforts.

If a few guys with 3D printers and a little spare time on their hands can make an extra mask or two a day, so a friend or family member who is a nurse or doctor has one or two extra masks to get them thru their task...that’s worth the effort.

I think anyone with a reasonable grasp of the situation understands a guy with a 3D printer isn’t going to pump out enough PPE to supply a whole hospital or anything.

2.4 hours for each printer to print 1 seems like a very slow process.
do they reuse those pieces and just replace the inserts?
sanitize some or all parts?
or just throw it all away after one use?

As for print speed, I have one printer making 2 shields every 1.5 hours, however that was already setup for faster printing using a larger nozzle. I wasn't ready in time with the second printer, larger nozzle is on order but who knows when it will get here.... from China!

I have enough materials on hand for another 300 shields, then we'll see if deliveries arrive in time to keep going.

Tuvix, good on you !! With so many Nurses and Drs. coming down with the virus while treating the infected you are making a difference , PPE is in short supply and I've seen a couple of news stories of people making cloth masks at home on their sewing machines, so if everyone did a little it would mean a lot .

I would have said "good effort - but it can't meet the volume needed." However, our local hospital just posted patterns online to sew masks and is asking for volunteers to sew masks at home. My position was that a factory can make a million a week, what difference will it make if someone cranks out a dozen in an evening. But apparently, it's actually needed. My wife has printed the patterns and is planning to get the sewing machine out tomorrow. I guess it makes sense. Instead of one factory making 10 million, maybe 1 million people making 10 each can make a difference.

Maybe we should start a go-fund me for those who need $ to buy materials to make PPE for those saving lives in our under equipped hospitals.

The idea is to make a reusable hard plastic "mask" with replaceable filter inserts. 3d printers can get them being manufactured quickly, but make up a few molds and obviously they could be put much faster.

Nothing to add, just wanted to thank you for your effort.

Great episode, btw. One of my faves.

That would be awesome, but have no idea how to assure funds would go to the right people and put to the right use... For me the biggest hurdle is insufficient printers to make more volume.

An idea of costs:
Printer: $400-800
Face Shields: $0.80 in materials
Production time: 45m-1hr per shield on average.

I applaud you guys with the printers. My wife belongs to a group of about 20 people knocking out about 450 cloth masks a day. Our local hospitals/health care are taking them and want more!

I started a small group of locals, we have 4 hospitals and a fire department on the waiting list. Once China opens back up for business this issue will go away, until then many hospitals are dependent on local supplies and as little as this is, the alternative is nothing.
