Print tough, long-lasting parts that won’t scratch or wear out from constant motion and friction, such as gears, bearings, and washers. You can even tap or drill the parts without them cracking or shattering.

Use these filaments with fused filament fabrication (FFF) printers. Because of their relatively high melting point, a heated printer bed is recommended. These filaments also emit fumes when printing, so it’s best to use them in an enclosed printer or to remove the fumes with a fume exhauster. Store them in a sealed container with a desiccant so they don’t absorb moisture in the air, which can make them unusable.

Carbon-fiber-filled nylon filaments are reinforced to make them the strongest and most rigid nylon in this offering. They are abrasive filaments that can damage soft metal nozzles, such as brass and copper, so use them with hardened steel nozzles.

Tensile strength is the best measure of a filament's overall strength. Similar to the stress applied on a rope during a game of tug-of-war, it's the amount of pulling force a material can handle before breaking. A higher rating means a stronger filament. A tensile strength of 5,000 psi and above is considered good; 12,000 psi and above is excellent.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.

Parts made with these filaments remain strong and rigid in temperatures that would soften most plastics. They are a lightweight alternative to machined metal parts. Use with a fused filament fabrication (FFF) 3D printer to make parts that will be used near ovens, engines, and other hot machinery. These filaments require an all-metal extruder to reach the recommended printing temperatures. Print parts onto a heated bed to keep them from warping as they cool.

To skip the annealing process, use carbon-fiber-filled PEKK filaments. Once they are printed, they tolerate the same amount of heat as unfilled, annealed PEKK, while producing parts that are stiffer and more impact resistant. These filaments also meet UL 94 V-0, which means they self-extinguish within 10 seconds if they catch fire, and won’t cause additional fires by dripping.
