3D Printable Respirator Mask

1. 3D-printed 2-piece face mask.
2. Large filtration area to improve breathability.
3. External filter attachment keeps contaminated fabric outside mask.
4. Flared facial edge, straightened nasal bridge, and thinner outer walls create a wider range of fit.
5. Custom anchor points to offer more versatility in the attachment of head straps.

Yes, this has been a collaborative project with people across the inland northwest. Reach out to us by emailing engr-covid19@uidaho.edu

No, we have not done filtration testing with any of the materials. A useful website for materials is the following:

There are other sites that make recommendations on shop towels, but we have not confirmed their findings at this point. It is unclear at this time if we will spend time in this area… it is under discussion. We have purchased 3 different types of shop towels, two of which seem promising. These are Toolbox brand shop towels and Heavy Duty Paper Wipes from McMaster-Carr. Other recommendations are listed on the Suay website and claim to have compared filtration capability with a commercial particle counter. However, we did notice they recommended the Toolbox towels in a previous article and then do not mention them in their Suay site. We have not yet investigated this difference due to time constraints.

Surgical wraps from Halyard come in different grades from H100 to H600 where the higher number offers higher filtration at the cost of lower breathability. We have samples of H200 and H500 and both are adequately breathable with 2 layers.

Yes, we should be able to scale down the model. Please email engr-covid19@uidaho.edu with a description of your need.
