Prusa unveils cheap carbon-fiber ESD filament to shield electronics

Prusa just launched Prusament PETG ESD, a new 3D printing filament packed with carbon fiber and carbon nanotubes designed to safely dissipate static electricity. This material is aimed at electronics manufacturing—think custom trays for handling PCBs, soldering fixtures, and IC carriers—rather than just hobbyist projects. It protects sensitive components from electrostatic discharge during production.

At $56.99, it undercuts competing ESD filaments from 3DXTech and Polymaker, while adding carbon fiber for better dimensional stability and less warping. For small-scale manufacturers and indie hardware developers, this means they can quickly print anti-static tooling on-site, avoiding costly CNC-machined ESD trays. Prusa already uses the filament in its own factory to prevent issues during powder coating, proving its utility in real-world electronics assembly.
