Discover all Nylons:

This filament is made of polyamide 12 reinforced with 8 % of aramid fibers. Its benefits are tribological properties, great chemical resistance, high stability under a wide range of temperatures, and great processing.

All of these make it suitable for the fabrication of products like an unwinding wheel, bearings, or cogwheels. It's a durable material that resists a wide range of chemicals, including car fluids.

    Great Engineering Filament

    Other than drying, AF80 is surprisingly easy to print with a 0.8mm nozzle, on a Bambulabs X1C, engineering plate, with Magigoo PA.

    Like FX256, AF80 parts are tough, even below freezing, or wet. AF80 doesn't seem as stiff as PC, or even some CF & GF filaments but it's stiffer than FX256. The upside to not being quite as stiff is that AF80 is less brittle than some PA-CF filaments I've tried. This also warps noticeably less than NylonFX256 and shouldn't creep over time (haven't confirmed this).

    My only complaint is that there's no grey/black option. AF80 might look really interesting mixed with the natural aramid color. The existing yellow/beige looks like an old ABS computer case from the 1990s - but this is a very minor complaint for an engineering filament.
