@PatrickHu4 @genomejunkie @willsuh76 @kardiologykazi @AHRavandi @MitulPPatel1 @bkolskk I assume you summoned the car to complete your delivery experience without having to venture too far from your door.

@nick_lawyer @Intermountain3D @SableSys @kevinnbass Same. EPDM window seal.

Happy to report that we’ve developed a 3-D printed mask. Passed N95 equivalent fit-test with Bitrex (surgical wrap as filter, readily available). Wearable all day. Mask can be resterilized/reused. Nylon-12. Thanks to @Intermountain3D for co-development. #COVID19 #PPE

@Godmstbcrzy @Intermountain3D See instructions. The design requires epdm seal for correct fit and comfort.

Mask STL files open sourced — https://t.co/HAyMY6uXN7. Reiterating that masks only perform as described when printed on commercial-grade SLS platform. Require adhesive face seal, filter, and tight elastic straps. Recommend FIT TESTING prior to use. #PPE #COVID19 #SARSCoV2

Credit to Dr. Bruce Spiess from @UFHealth for Halyard H600 two-ply spun polypropylene filter idea. Works great in our testing with no shortage.

Please refer to our website for all details, including a link to a mask that can be printed on filament printers. Also includes order details. https://t.co/HAyMY6dmox

@DownWithData @Intermountain3D The masks require a commercial SLS printer, not a filament printer, to produce (masks are very thin, allowing flexibility and close fit). We are happy to provide schematics to anyone with this capacity. Please email Lynn Hoffmann at [email protected] for details.

@VivienHLee @Intermountain3D Surgical wrap has been proposed as an alternative to N95 filter material by the University of Florida. We tried it, and it works well. Usually available in abundance. See above Tweets.

@kmobs @Intermountain3D @NayaMohanMD Not an industrial filter. Can use surgical wrap, which is a good substitute for unavailable filter medium. This is a highly modified and redesigned Montana Mask. Requires SLS printer to achieve specs required for proper fit. Montana Mask is as a surgical mask substitute.

[Ilyas Colombowala, MD, FACC, FHRS @RhythmMD]

@Dr_Bowser @Surgeon4aCure @Intermountain3D The masks have an EPDM sealing gasket, which is quite comfortable.

[Ilyas Colombowala, MD, FACC, FHRS @RhythmMD]

@footankle @Intermountain3D Yes. The masks were designed because of the lack of available PPE. In order to function as designed, they need to be very thin (requiring an SLS printer). Please email Lynn Hoffmann at [email protected] for details.

[Ilyas Colombowala, MD, FACC, FHRS @RhythmMD]

@SableSys @kevinnbass @Intermountain3D We are happy to provide STL files to anyone with an SLS printer. Please email Lynn Hoffmann at [email protected] for details.

[Ilyas Colombowala, MD, FACC, FHRS @RhythmMD]

@myampas @Intermountain3D See message from me — we’ll send some.

[Ilyas Colombowala, MD, FACC, FHRS @RhythmMD]

@elfphotography1 @Intermountain3D Yes, we’d be happy to share to increase availability, but these masks require an industrial printer. Please DM @Intermountain3D for details.
