For what it’s worth I am not sure they manufacture all of their own filament. Most companies that do at some point give a video tour or some photos of their factory floor, I have never seen theirs but have for other companies like Protopasta I have.

They for sure used to sell SABIC filament.

I personally don’t care for this company, the owner is abrasive at conventions and has done things like lawyer up to C&D competing filament companies. One company got a C&D because the color on one of their “about” webpages was “too similar”
