Prusa Research introduced Prusament PETG ESD on 10 November 2026, a new 3D printing filament designed specifically for direct contact with sensitive electronic devices. This carbon-filled filament incorporates both carbon nanotubes and carbon-fibre reinforcement to combine electrostatic dissipative properties with improved dimensional stability and thermal resistance.
The filament’s electrostatic dissipative qualities come from carbon nanotubes, rather than the more common conductive carbon black used in many ESD-safe materials. This distinction enhances the protection of static-sensitive electronics during manufacturing or prototyping. Prusa Research states on its product page:
“Prusament PETG ESD is a carbon-filled material with electrostatic-dissipative properties, suitable for direct contact with sensitive electronic devices.”
Unlike typical ESD-safe filaments, Prusament PETG ESD also contains carbon fibres for reinforcement. This addition strengthens the material, improving its dimensional accuracy and resistance to heat, which is critical for producing functional components in electronics production, according to 3DPrinting.com.
Tom’s Hardware reported the filament’s launch, noting the $56.99 price tag for a 1 kg spool and emphasising its intended use beyond hobbyist applications, targeting electronics manufacturing instead.
Technical specifications shared by 3DPrinting.com include a volume resistance of 7.7 × 106 ohms and a surface resistance of 7.1 × 105 ohms measured on the filament’s top layer. These values support its effective electrostatic dissipative functionality, although definitive confirmation of these figures from Prusa’s own datasheet is still awaited.
The filament’s recommended print settings suggest a nozzle temperature near 250°C and a heated bed above 80°C to optimise performance and stability. The material’s ability to dissipate electrostatic charges while maintaining mechanical and thermal integrity marks it as a suitable choice for manufacturers requiring static protection combined with durability.
This launch positions Prusa within a growing market for specialised filaments tailored to industrial use cases. The combination of carbon nanotubes with reinforcing carbon fibres appears novel among ESD 3D printing materials, offering an enhanced balance of electrical and mechanical properties.
Further independent testing and feedback from electronics manufacturers will clarify the filament’s practical advantages in industrial environments. Cape Flats readers interested in emerging 3D printing technologies for electronics and industrial prototyping may find this development notable as additive manufacturing continues to expand into specialised fields.
The exact market availability and regional pricing for the filament remain to be clarified, with reported prices differing between global and European outlets. We will follow up with Prusa Research and monitor industry reviews for expanded insights and verified performance data.
