An open source 3D printed face mask shared by the Billings Clinic Foundation, for instructions and download link for the 3D file can be found here www.billingscl...
For more information on this mask go to www.makethemasks.com. They have put testing results, FAQ and directions to make these masks on the website to be a resource for those printing the masks.
How about cutting off a length of soft rubber tubing, cutting a slit along the longitudinal axis (long ways) of the tube going the full length, then slipping the tubing onto the edge that contacts the face. At the point where the tubing comes together one could apply a little hot glue to complete the seal. Maybe apply a bead of glue inside the tube too!
The instructions *do* say to add a rubber gasket around the edge. Fits nice and comfortable that way. Also, HEPA filters from air filters (home, car, even from vacuum cleaners) are great options for inserts that let you breathe but still filter the air.
Sewing seems like the way to go. Pity sewing supplies and fabric stores are closed down. home improvement ones aren't though. There are also super quick and flexible hot glue gun constructions, but low durability and bad to disinfect. Maybe lightweight printed frame like constructions can be useful where you span a filter or a piece of cloth into them. They should be quick to print, easy to adjust to face with hot water, and maybe you can quickly weld them shut with filament pins and soldering iron. Maybe they can have an area where cloth wraps in on itself and some kind of installation frame that is then removed and reused, so the face is in contact with softer cloth.
like the software to make the file printable? usually people use free programs like Ultimaker Cura or Slic3r. To make the 3d model? Lots use blender or tinkercad. 3D printing has a lot to do on computer, I spend more time on my PC than printing lately.
I've made one each for myself and my wife and the same for my brother and his wife. It's easy to make different sizes just by adjusting the ratio in your slicing program. I found the standard size fitted me but was too big for my wife so made hers at 90%. I did the same for my brother's pair. I used self adhesive neoprene foam strip bought from Ebay around the edges to get a perfect and comfortable seal. I had some proper 3M N95 filters I'd already bought last month, so will use those first but also bought some HEPA vacuum cleaners bags for if they run out. I don't think I'd trust ordinary cotton material to do the job safely.
Hi my wife works in the Emergency room at university hospital in tamarac Florida there is such a shortage of face masks that she sometimes has to work her shift without one we would gladly buy one from you and pay for shipping if you can help let us know where to email you and i will email you her work credentials and a number to the hospitals Emergency room that you can verify that she works there.
I think you brought up a lot great points in this video. I agree with everything you said. I'm just going to help the wife sew some up for us.
Where are you?
Covid
@@NMS2005 WOW, what do you mean? did he pass away?
With the covid pandemic it disappeared. No one knows if he is still alive or not...

I used elastic filament and it is amazing. Seals perfect to my face
Yes, I want to try these in TPU.
I made these masks and same problem. Filter area is too small and it is too hard to breathe.

Print one at 90 or 95% scale and see if that helps. I printed one at 90 for my wife and it even fits me pretty good.

use window insulator for seal

What is the 3d printing software used ? Can anyone help me with the software name?

I'm printing a few myself. Maybe I'll send some out that way!
sand it down.
i want to see 3D printed toilet paper
LOL
that's gonna be hard to push..
