# Prusa Launches Carbon-Fiber ESD Filament for Electronics Manufacturing New electrostatic-dissipative material offers affordable production-grade solutions for sensitive electronic components. - **Source:** [Tom's Hardware](https://www.tomshardware.com) - **Published:** 2026-11-11 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/4147c366-a340-4e6b-baed-e3dc1862f6e5 ## New ESD Filament Launch Prusa Research introduced Prusament PETG ESD on Tuesday, a specialized filament designed for electrostatic-dissipative applications. By incorporating carbon fibers and carbon nanotubes, the material protects sensitive electronics from static discharge. This product aims to serve professional electronics production environments rather than just hobbyist projects, offering a unique material composition. ## Competitive Market Pricing Priced at $56.99 for a 1kg spool, this new filament undercuts existing market alternatives significantly. Competitors like Polymaker and 3DXTech offer similar ESD-rated materials at $65.98 and $105 respectively. Prusa’s offering stands out as the only option currently available that combines carbon fiber reinforcement with electrostatic-dissipative properties for users. ## Targeting Industrial Production Prusa is positioning this filament specifically for manufacturing tasks like PCB fixtures, soldering holders, and IC transport trays. By enabling on-site printing of these tools, companies can bypass the long lead times and high costs associated with traditional CNC-machined ESD fixtures. It provides a scalable solution for smaller hardware developers. ## Material Performance Characteristics While official datasheets remain unpublished, Prusa indicates the filament features increased stiffness and reduced toughness. These mechanical properties mirror those found in their existing PETG Carbon Fiber line. However, the specific carbon fiber concentration may differ, as this material prioritizes electrostatic protection over the raw structural strength required for parts. ## Internal Production Application Prusa actively utilizes this new PETG ESD filament within its own internal manufacturing facilities. The company employs the material to prevent overcoating issues on the edges of its print sheets during the powder coating process. This real-world application demonstrates the material's reliability in high-volume, repetitive industrial production environments today. ## Enhancing Dimensional Accuracy The integration of carbon nanotubes and fibers serves a dual purpose beyond static protection. These additives improve the dimensional accuracy of printed parts while simultaneously minimizing warping during the cooling process. Such stability is critical for manufacturing fixtures that must hold delicate electronic boards securely during assembly or testing phases. ## Beyond Hobbyist Utility Although hobbyists often use standard PLA or PETG for basic enclosures, this ESD-rated material provides essential protection for sensitive components like Raspberry Pi or ESP32 boards. Prusa emphasizes that the primary value lies in production-line efficiency, allowing smaller manufacturers to implement professional-grade ESD safety measures without the prohibitive costs. ## Future Performance Outlook As independent testing and official strength profiles emerge, the true value of this filament will become clearer. If the mechanical performance proves comparable to standard carbon-fiber PETG, it could become a preferred choice for diverse industrial applications. The market now awaits further data to confirm its long-term durability and utility. ## Sources covering this story - https://www.tomshardware.com/3d-printing/prusa-launches-new-carbon-3d-printing-filament-for-electronics-manufacturing-carbon-fiber-and-carbon-nanotube-filled-material-dissipates-electrostatic-energy-for-static-sensitive-electronics — --- _Summary written by Brifing from the original reporting.
