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.

Thermoplastic-blend filaments have three times the wear resistance of nylon. While using an enclosed printer or fume exhauster is best for the other filaments, it is required for the flexible thermoplastic-blend filaments.

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.
