Hi All,

Some of you may or may not have already seen this but reaching out to everyone who has a 3d printer can help support our communities by printing simple face shields to protect the healthcare workers. Please see this video on how simple it is to make one:



If you come across any healthcare personnels/hospitals needing them, please post them here and I am sure the RCPowers community can help!

I have been printing these out for my neighbors and friends,it uses make up pads in the breathing filter or just cotton.You warm it up slightly with a hair dryer or hot water to form it to your face.They must be cleaned 100% after each use and must not have any space between the mask and face.WIN_20200326_22_24_57_Pro.jpg

Looks like a large rubber band that's been cut and tied again?

Thanks for doing this! It has been a while since I have posted on the forum. I work as a cardiologist in Canadian hospital and the prospect of encountering this disease is unnerving. Please remind everyone to physically distance themselves wash often, and cover up. Right now that seems to be our only real weapon to beat this virus. I hope to be back in the skies again soon.

The best material for home made masks along with a how to video on youtube by a dr. useing HEPA vacume bag material which filters 98% seemed to be the best I've seen.Along using it as a filter placed my mask totally covering my nose and mouth is the way that I'm going to go with.

It looks like the 3d printed masks (esp. the N95 grade) are regulated by FDA so don't think we would be able to do much to help the healthcare workers but could certainly make them for your own protection. However, for face shields there don't seem to be much regulation around it and thats why more and more hospitals are okay to use the 3d printed face shields but want to stay away from non-traditional sources for "N95-grade" printed/custom masks.

Yeah, regulation is pretty heavy on a lot of stuff like that, face shields seem to be the best option for helping out rn.
I did see this article/mask design; basically uses HEPA filter or similar in a 3D printed shell. Looks like some medical folks at the UW think it's a good design and are doing some testing with it.
