Carbon Fiber Filled—Carbon-fiber-filled ABS filaments make rigid parts that are difficult to bend and break. Their parts can also be threaded and machined more easily than ABS filaments without a filler. Carbon-fiber-filled filaments are abrasive, so you should use them with an abrasion-resistant nozzle. They will wear out other nozzles.

Fiberglass Filled—Fiberglass-filled ABS filaments make parts that are stronger and less likely to warp or shrink than ABS filaments without a filler. Fiberglass-filled filaments are abrasive, so you should use them with an abrasion-resistant nozzle. They will wear out other nozzles.

UL 94 V-0—Filaments rated UL 94 V-0 meet strict flammability standards. Use them to create holders, guards, housings, and other parts that protect sensitive, flammable equipment and machinery.

Static Dissipative—Static-dissipative filaments make parts that protect equipment from electrostatic shocks by diverting electrostatic discharges in a controlled way. Use them to create tool handles, tote trays, enclosures, and other parts that are used near sensitive electronics. To adjust the surface resistivity of your printed part, change the temperature of your printer’s extruder. As the extruder’s temperature increases, the printed part’s resistivity will decrease.

Tensile Strength—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.
