Print water-resistant packaging or other parts that will be used near sensitive electronics with these filaments. They combine polyester with a static-dissipative compound, which keeps static from building up and reduces the risk that a sudden shock will damage equipment. Parts made from these filaments can be splashed with water or stored in humid areas without degrading. Designed for use with fused filament fabrication (FFF) 3D printers, they are more durable than PLA and easier to print than ABS.

To prevent parts from warping while they cool, these filaments must be printed onto a heated print bed. Although finished parts are moisture resistant, the filaments themselves are sensitive to humidity. Store them in a sealed container with desiccant or in a dehumidifying cabinet.

PCTG holds up to a wide range of acids and bases without breaking down. It is often used for printing parts that will be exposed to chemicals and oils.

Use an electrical resistance tester to make sure your part meets proper resistivity levels. In general, the target surface resistivity for printed parts is 10⁷ to 10⁹ 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.
