    It’s necessary Flex TPU filament (hard to find and printing)

    Please, can we have the STL file to print 3D valve.. Our region is in a critical situation, and we have still tens companies, local university, and private persons who are ready to print them to help our population.. @Davide Sher, be human, please

    It’s not hard to find nor print.
    Extrudr based in Austria has high quality industrial TPU safe for foodcontact.
    their medium TPU is ideal for this. It prints very easely. They have stock and can deliver quickly
    Check out the specs of the material here:

    https://www.extrudr.com/en/products/catalogue/?material=117

    please share this info… they have easy to print materials.
    Also their GreenTEC and Greente PRO range is FDA, REACH and ROHS approved. have high temp resistance and cna be printed as easely as PLA. those are safe materials to use.

    Trying to download this for my Ultimaker 3 printer and it won’t recognize the main mask part. Any ideas?

    Disregard my previous post, How do I get the time to print down from 3 H 17 min?

    Thanks

    Can we print this with a SLA printer? Specifically would formlabs printers with their conventional materials work for this purpose? We are trying to respond to a hospital’s request, but want to make sure that the printed samples are safe to use.

    I print TPU quite often. I am currently printing up the Mask V STL with some tweaked TPU settings I normally use. If successful I will upload the setting for the community.

    Any advise on joining the mask’s lower chin guard with the main body? I am going to try heat welding with a heat gun and see how that turns out.

    Good luck everyone.

    What are you guys using as an appropiate filter?

    sorry, I am getting confused: the Copper 3D mask works due to the soecial material used. So why do you recommend using TPU ? Also, as already asked, what is hindering the virus entering the mask, what sort of tissue is used? If we all start printing masks, they should better work well!

     

    Thanks for your help,

    Hi,

    Acoording to the website of the creator this should be printed in PLA and at 55º – 60º C with the use oof hair dryers or warm water should take the correct shape of the face. But they mentioned and special material.

    Check their website: https://copper3d.com/hackthepandemic/

    Just wanted to give some feedback on the mask. From one of our engineers:

    I was able to printed the design from Copper3D last night, see attached images.  It printed without any issues but as it is currently designed I don’t think it will work well as a mask.  As you can see in the second image where I tried to fold it, the material is far too stiff (used PLA as that was cited in the article) and does not have any hinge elements (thinner cross-section at bend locations) or locking features.  Also, it is completely missing any kind of soft sealing material needed in order to pass leak requirements.

    It looks like it was too stiff to bend…

    You have to use a heat gun to soften it and then flex it to fit the face. It also requires the use of antimicrobial or antibacterial PLA. You may be able to get around this with good filters but not sure.

    Hello all,  I’m new to this whole thing, but I have design improvement ideas regarding this mask design. So, the current situation with traditional N95 masks is that they are formed with the actual “melt cloth” which is the filter material itself. The human lyranx is only 4 to 5 MM round, so I think the traditional design is very wasteful. As far as I have read, the supply chain issues are around this “melt cloth” and the manufacture of it. Some have asked “What do I use as a filter?” for the 3D printed design. What I suggest, is finding air conditioner filters that are “HEPA” and re-purposing that cloth as filters. I took a very old painter’s mask, that allowed replacement filters, and hacked new filters cutting to form circles from a new HEPA A/C filter.

    I think the current 3D design above is “good” – but I would like very much if someone could change it for me. The current design calls for two round filters, left and right side. A “round” filter is not optimal from a melt cloth perspective, as a circle must be cut from a square of material, therefore having a large waste percentage. A square design would allow filters to be cut with almost zero waste.  Also, I think having two small filters is optimal. The mask should have one filter – perhaps a rectangle shape. I don’t know the optimal “size” the filter hole should be – again, a human takes in 100% of our air through a 4 to 5 MM opening in our throats. So assuming melt cloth filter causes a… (I am guessing here) a 50% reduction in that effectiveness, then one might say, a 2x ( 10mm), 3x (15 MM) or 4x (20 MM) sized filter is really all that is needed.  Again – plastics are cheap and plentiful – its this “melt cloth” filter material that is in very short supply and needs to be maximized to produce as many masks as possible.

    If someone is willing to work with me on changing the design, I’ll go out and purchase whatever 3D printer is recommended (and forming materials) to start trying to print some prototypes. Asking for your help to prove the concepts above.   Thank you all.
