Introduction: 100% 3D Printed Covid Mask

About: I am passionate about racing cars and racing technology. I build designs that hopefully shock and amaze the 3d printing world, in an attempt to push the limits

100% 3D printed mask. You can print everything except the filter.

The mask has a replaceable filter that can be changed.

No bolts or screws required. You need to seal the TPU mouth and nose part to the top mask part. You can do this with glue, epoxy, 3m bed tape, RTV, etc..

Needs no supports. The mouth and nose part needs to be printed in TPU at 0%.

The other parts need to be printed in rigid material like PLA, ABS, PETG, etc.

If you need to resize, use the 90% small size mask.

STEP file included if you need to or want to modify.

    Very nice looking mask, but the filter part is a bit small. If the same volume of air would travel through a filter with a bigger surface when using the same filter material, you should be able to breathe more easily. If you were to double up on filters you could be breathing with the same ease as now, but with better filtering. I have a commercial mask that I used to use with abec2 filters, so I gutted an old screw-on filter and am adding filter material to that.

    Thanks for the comment. It actually isn't a small hole/opening. Have you tried it? It's very breathable.

    I wear respirators all the time and my first priority was breathability. The easier it is to breathe, the more you will keep it on and wear it.

    The front filter has the same area as the nose and mouth. there is no cross flow where gases being exhaled bounce off of the surfaces and reflect on an inhale. All gases are expelled out of the filter, so it is easier to breathe.

    The .step files are downloadable, so if you do have a concern, you have the files available to design your adapter for a larger filter.

    Stay safe.

    I like this a lot. With the appropriate filter medium, you could use this for either a shop dust mask or health reasons. Going to investigate the purchase of a 3D printer now.

    As long as people hopefully see it, they can print it out or adapt the .step file to be safe.
