Polar Filament is a Filament Manufacturing company based out of Troy, MI. We extrude all of our filaments at our factory in Troy. Our roots come from industrial manufacturing, so quality is a necessity. We made it our goal to make the highest quality filament possible, and release all of the data collected during the manufacturing process so you can double-check each and every roll. Polar Filament is a brand of filament, owned and operated by Douglas Innovation. Douglas Innovation is a startup, founded in 2017 to create automotive prototypes in the Metro-Detroit area. Over the years, we’ve expanded into other manufacturing areas such as 3D printing, Circuit Boards, and Wire Harnesses.
