Prusa has introduced a new ESD-safe 3D printing filament, Prusament PETG ESD, designed specifically for electronics manufacturing. The material incorporates both carbon fiber and carbon nanotubes to provide electrostatic discharge protection while enhancing dimensional accuracy and reducing warping during the printing process.
The new filament is priced at $56.99. This makes it more affordable than comparable products from competitors, such as 3DXTech, which sells its ESD-PETG for $105, and Polymaker, whose Fiberon PETG-ESD is priced at $65.98. Prusa's offering is currently the only one on the market that includes carbon fiber reinforcement.
Prusa targets this material for industrial applications, including PCB fixtures, soldering holders, and IC transport trays. The company suggests that using this filament can reduce manufacturing costs by replacing expensive CNC-machined ESD components with on-site 3D-printed alternatives, benefiting both small-scale manufacturers and independent developers.
While Prusa has not yet released a full technical datasheet, the company claims the filament offers increased stiffness and reduced toughness, comparable to its existing PETG Carbon Fiber product. Prusa already utilizes this new material within its own production lines to prevent overcoating issues during the manufacturing of its print sheets.
