Tamarack turns its talents to Montana masks
Healthcare professionals facing a shortage of personal protective equipment can now access masks 3D-printed by aircraft winglet experts, Tamarack of Idaho.
The reusable, protective respiratory masks are based on a design developed by doctors in Billings, Montana.

Sandpoint, Idaho aerospace innovator Tamarack Aerospace Group is repurposing its high tech 3-D printing capabilities and other connections to help its local community now facing shortages due to the COVID-19 pandemic. “When we heard that our local hospital, Bonner County General Hospital, was running low on some vital protective gear, we tapped into our resources to see where we could help meet their needs,” says Tamarack president Jacob Klinginsmith.

Tamarack's talented team of aerospace engineers have been 3-D printing reusable, protective respiratory masks based on a design developed by doctors in Billings, Montana appropriately named the Montana Mask. The masks include a small industrial filter which provides equivalent protection to the N95 mask. Using in-house company resources like CAD and multiple 3-D printers, Tamarack has been able to produce more than 60 masks, and the efforts will continue until the need subsides.

Meanwhile, others on the Tamarack team have been using their crafting skills to sew face masks to help meet the urgent need, and employees have sewn over 50 masks. The sewn and 3D printed masks are being distributed directly to Bonner County General Hospital.

“I am proud to be a part of a community where friends, neighbours and businesses come together in times of need. We have a team of talented and generous people who are excited to take on this challenge,” said Tamarack's chief engineer, Nathan Cropper.

Tamarack also reached out to its connections in Shenzhen, China to help Bonner County General Hospital source 2,400 FDA approved N95 masks when the hospital's normal supply chain was experiencing serious delays.

“Tamarack is helping in these small ways, but our hats are off to the front-line folks working tirelessly to treat, study and contain the COVID-19 virus,” says Klinginsmith.

Tamarack encourages others interested in printing these or similar masks to visit the Billings doctors' website at and to coordinate with their local hospitals.
