Not only do parts printed from these filaments protect sensitive electronics, but they also hold their shape in temperatures that would deform or degrade most plastic. Use them to make parts for hot environments, such as engines, ovens, or lighting equipment. These filaments combine heat-tolerant plastic with a static-dissipative material that keeps static from building up and prevents shocks.

Use these filaments with a fused filament fabrication (FFF) 3D printer. They require an all-metal extruder to reach the recommended printing temperatures, and should be printed onto a heated bed to keep parts from warping as they cool.

PEI filaments have electrical-insulating properties, which make them good for printing circuit-breaker housings and semiconductor components.

Use an electrical resistance tester to make sure printed parts meet proper resistivity levels. In general, the target surface resistivity for PVDF is 10⁶ to 10⁹ ohms, and for PEI and PEKK it's 10⁶ to 10⁷ ohms. To adjust your measurements, change the temperature of your printer's extruder. As the extruder's temperature increases, so will the printed part's resistivity.

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.
