Filtered Face Mask · 模型 255853
A 3D printable face mask with a tight fitting filter cover using a replaceable cloth type filter. Made for the Covid-19 epidemic amongst us. After 3D printing the mask you'll need to seal it with epoxy or enamel or something else to make it air tight as FDM 3D printing isn't air tight. I assume the other 3D printing technology isn't either but FDM printing certainly isn't. For filter material you should use something that can filter out down to 3 microns. I cut up an air filter designed for a house's air conditioning system. I got one with an MPR rating of 2500 which is equivalent to about a 13.5 MERV rating with an efficiency of about 96.5%. The inner filter box cover is a tight fit with the material caught in between, too thick of material and it may not work. You will have to resize the cover if this one won't work for your needs. You can also try cutting enough material to cover the entire inside of the mask though I don't think that's necessary if you seal the mask, it is however another layer of protection and won't hurt if you can spare the material and if you can get it to form to the shape of the mask correctly; I failed horribly at that task. I also couldn't get it to stick to the mask with glue and it started to come apart like cotton candy and the strings of the filter's fibers started sticking to everything making a big mess. I've uploaded 2 Solidworks(2019) files: Covid-19 Filter Mask-JB300 Imported.SLDPRT Covid-19 Filter Mask-JB300.SLDPRT Essentially they're the same with the exception of the 2nd one in which I deleted the imported .STL file (as suggested in the tutorial) from which I base lined my drawing from. I've included the Imported version if you wanted to see how it was done. The assembly, .STL & .STEP(AP214) files were created from the 2nd Solidworks files. Forgive my terrible version of the simulated cloth file. I have no idea how to make a realistic version of that and to be fair though, I only quickly created it for illustrative purposes. :-) Visually the attachment points looked better with every edge fillet'd, but it didn't seem to print as nicely so I removed them. I would love to see what others do with this file and see how they improve on it. If you do please send me a message to have a look at your creation and/or improvements. I'd like to extend out a BIG THANK YOU to Fred Swug and his tutorial on how to make a face mask with Surfacing using a .STL file imported into Solidworks. His tutorial was my g...
