To all of you on the frontline - Thank you for all that you do. We are truly grateful.

We have worked day and night to produce these as quickly as possible and to get other machine and injection shops across the country up and running with mask production as well. Currently, Spark R&D has sufficient inventory of masks and filters and can ship orders right away. They are now available beyond the frontline to the general public as well.

Important Notes: The Montana Mask is not an FDA or NIOSH approved N95 replacement. These masks are intended for use past crisis capacity if there is no conventional PPE available. Please closely read the info available in this document and on to decide if they are right for you.


Important Notes:

  • Mask Cost: Masks are $2 each and come without straps. Filter material can be purchased separately. 
  • Sizes: There are two mask sizes, small and large. Typical demand is around a 50/50 or 60/40 mix of sizes. The filter frames are the same for both sizes and are interchangeable.

The Montana Mask Story

Background of the 3D Printed Mask

The Montana Mask was designed out of Billings, Montana by Dusty Richardson, MD, Spencer E. Zaugg, DMD, and Colton Zaugg in the wake of PPE shortages due to the COVID-19 crisis. It was designed to be an open-source, grassroots movement, where anyone can download the files and print the masks on a 3D printer. The idea is that anyone with access to a 3D printer could help to supply healthcare workers who were not able to secure conventional PPE. The story aired on CNN on March 23, 2020:

Since that time, the file has been downloaded in 148 countries and with the flurry of phonecalls and emails, it became abundantly clear that access to PPE worldwide is even more limited than anyone could have imagined.

The move to injection-molded Montana Masks

Will Ritter, co- owner of Spark R&D, heard of the CNN story and wanted to get involved. While Spark R&D does indeed have a 3D printer and would have been more than willing to join the printing efforts, Will reached out to Dr. Richardson with an idea. With the volume of masks needed and the short window before healthcare workers run out, injection-molding the masks would be a much more efficient and timely solution. 3D printing masks takes around 3 hours for one mask. Injection molding could be as quick as one every 45 seconds. Spark R&D could use the 3D files provided and re-design them for an injection molded mask. With in-house design, mold-making, machining, and injection molding capabilities a prototype was made in just four days and the final product was approved on day six, on March 31. The first 2400 masks were delivered to the Billings Clinic on April 4th.
