This time of year, staff at Cline Library’s MakerLab, Northern Arizona University’s large-scale 3-D printing environment, would normally be gearing up for the end-of-the-semester rush. Instead, they have dedicated resources to addressing a national shortage—medical masks.
To assist Coconino County health care workers on the front line of the coronavirus (COVID-19) pandemic, the MakerLab partnered with Guardian Air, a division of Northern Arizona Healthcare, to 3-D-print personal protective masks for medical professionals in the Flagstaff area that would otherwise be without.

Doctors from the Billings Clinic in Montana created the computer model to print these masks, which are designed for use with a fabric medical mask or filter insert. Made from a plastic material called PLA, the mask design is sturdy, non-toxic, cleanable and most importantly, reusable.
At two inches by two inches, the permeable area of the 3-D version is much smaller than traditional medical masks, meaning less filter material is required, which Holthe said is crucial in times when supplies are dwindling.
The MakerLab began printing masks at cost last week, and the printers have been running non-stop since. In four days, NAU finished 100 masks for the medical workers at Guardian Air.

“This pandemic has brought to light what individuals can do to make a difference and how the university and community are intrinsically linked, sharing not only expertise, but also bringing creativity and innovative ideas to the local level,” dean and university librarian Cynthia Childrey said.
The 3-D printed mask is not intended to replace standard protective equipment, such as N-95 masks or surgical masks. Use of the 3-D mask has not been fully tested and has not been approved by federal or state authorities. NAU makes no representations or guarantees regarding the safety, efficacy or appropriate use of this product in any situation.
