I'm not sure how it's confusing. Is it any more confusing than "v8" also being a type of internal combustion engine or blender also being a kitchen appliance?
v8 as a drink and as an engine.
blender as a piece of software and as an appliance
filament as a physical building material and as a physical rendering material.
One of these things is not like the other (or rather, one of these things sounds very much like the other).
