        Once again, this is not a working mask, this is a scam to take advantage of the current crises and sell magic unicorn filament. Multiple people have verified that the printed mask is a completely non-functional prop. It's wasting community resources and sucking up bandwidth. https://twitter.com/Copper3D_Global/status/1240600322411659265 …

        Replying to @jprwg @eigenrobot

        very different beast than the one Naomi is rightly trashing, which is one solid piece of plastic too inflexible to seal to face can't see why this design - which clearly involves more manual assembly, including sewing a soft gasket where the mask joins the face - wouldn't work

        Replying to @eigenrobot

        The critical part of this design seems to rest entirely on whether it can make a seal on your face and what the quality of the filters are on the front. Anything sub 11μ should do quite well. At least from what I've been reading.

        Everyone in the replies reports good sealing. Filter media are not difficult either.https://twitter.com/__ice9/status/1241619825912397824?s=20 …

        Typical vacuum cleaner bags can apparently achieve 95% efficiency as well, assuming reasonable quality sealing/fit around the edges-- https://smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/ …

        If it's not full face covering it's useless, because the viral strain can get into your eyes. This is a dust-mask at best.

        Tangential, but apparently electrospinning can outperform normal mask/cartridge filter media: http://www.ftene.com/product/b2c1.php … Requires an HV PSU, probably a hot box of some kind, and presumably a syringe and tubing usable at operating temps. Probably not very practical if hot.pic.twitter.com/La6vGgSBfi
