Polymaker has unveiled a new 3D printing filament designed to protect sensitive electronics from the destructive effects of electrostatic discharge (ESD). Called Fiberon PA612-ESD, this engineering-grade filament is reinforced with 10% carbon fiber nanotubes, offering a rare combination of mechanical strength, thermal resistance, and reliable ESD protection – without requiring post-processing or coatings.

Built for Protection and Performance

At the core of this filament is electrostatic safety, a must-have for those working with PCBs, sensors, or other static-sensitive components. According to Polymaker, Fiberon PA612-ESD has a surface resistivity between 10⁴-10⁷ Ω/sq, placing it squarely in the static-dissipative range, as defined by the ANSI/ESD S541 standard.

This means the filament safely dissipates static charges rather than allowing them to accumulate and potentially fry your hardware. It’s an ideal choice for printing protective enclosures, tool holders, or fixtures used in ESD-safe workspaces.

Strength Without Compromise

Beyond ESD protection, Fiberon PA612-ESD delivers serious mechanical performance. It offers:

  • Tensile strength: 84 MPa
  • High stiffness and dimensional stability
  • Heat deflection temperature: up to 157 °C

Despite its reinforced formulation, Polymaker says the filament is easy to print, with low warping and print speeds reaching up to 300 mm/s. It’s also AMS-compatible, moisture-resistant (thanks to vacuum-sealed packaging), and doesn’t require drying before use.

No Coating, No Problem

Traditionally, achieving ESD protection meant post-processing or applying special coatings. Fiberon PA612-ESD eliminates that step, making it easier for engineers, makers, and professionals to create ready-to-use functional parts straight off the print bed.

Polymaker also released a comprehensive explainer video on YouTube, breaking down the science behind ESD protection and how Fiberon PA612-ESD fits into an electronics-safe workflow.

If you’re building custom hardware, prototyping circuit boards, or simply want to safeguard your electronics from static shocks, Polymaker’s latest filament might be the one to trust.
