Polymaker Fiberon™ PETG-ESD /black/

It is suitable for electronics housings, trays and holders for electronic components, printed circuit board assembly fixtures, tools, and production jigs and fixtures. It is particularly useful in manufacturing, servicing and assembling sensitive electronics where static electricity must be controlled.

The recommended nozzle temperature is 250–290°C, with a build plate at 70–80°C. A nozzle temperature of at least 250°C is recommended for consistent ESD properties. High-speed printing is also possible if the printer and hotend can maintain the required volumetric flow.

No. Fiberon™ PETG-ESD can be printed at room temperature without an actively heated chamber. This makes it considerably easier to use than materials such as ABS, PC and other high-temperature engineering filaments.

Yes. A hardened steel or other wear-resistant nozzle is recommended because the carbon additives are abrasive and can wear a standard brass nozzle relatively quickly. A 0.4 mm nozzle is suitable for this material.

Yes, if the filament has absorbed moisture. Drying at 65°C for around 3 hours is recommended. With PolyDryer, use Level 3 for around 6 hours. Dry filament provides more consistent extrusion, a cleaner surface and better layer adhesion.

Its ESD properties depend on extrusion temperature. Higher temperatures increase the electrical conductivity of the printed part. In Polymaker's tests, surface resistance was approximately 1.6 × 10⁷ Ω at 250°C, about 4.7 × 10⁵ Ω at 270°C and below 1 × 10⁴ Ω at 290°C. Printing temperature therefore affects both mechanical quality and ESD performance.

It has a glass transition temperature of around 77°C, a Vicat softening temperature of around 86°C, and an HDT of approximately 72°C at 1.8 MPa and 76°C at 0.45 MPa. It is suitable for housings, fixtures and tools around electronics, but not for continuous use at very high temperatures.
