Prusament PETG ESD is a carbon-filled material with electrostatic-dissipative properties, suitable for direct contact with sensitive electronic devices. Unlike other materials, this filament contains both conductive filler and carbon fiber reinforcement, adding extra thermal resistance and dimensional stability. Plus, it doesn't release conductive filler into the surroundings.
The material's electrostatic dissipative properties are achieved through carbon nanotubes instead of conductive carbon black. The nanotubes don't release into the surroundings, which makes this filament safe for housings and other structural components of sensitive electronic equipment.
Unlike most ESD-safe materials, the Prusament PETG ESD contains both conductive nanotubes and reinforcing carbon fibers. These significantly improve its dimensional stability and thermal resistance. This means very little to no warping when printing large models.
Carbon fibers give the material a slightly rough matte surface finish with a black tone. This results in an overall expensive look.
Prusament PETG (red) and Prusament PETG ESD (black). The latter attracts the powder, preventing overcoating.
When powder-coating the print sheets, some of the particles accumulate on the bottom edges. This causes an uneven coating. We use PETG ESD for printing a fixture that attracts part of the paint, preventing unwanted overcoating.
The ESD-safe PETG allowed us to make a functional rapid prototype, which was used for testing in a real environment before manufacturing the fixture with metal and in large quantities.
Prusament is a premium-grade material made by the same people who build the printers. Every spool is manufactured in-house with consistent color and high diameter precision. You can verify it yourself, down to the last meter.
Every Prusament color is formulated and locked to a documented spectroscopic recipe. We test every batch against the standard before it ships. The result: if you run out mid-project and order a second spool, the colors will match perfectly.
Our diameter tolerance is the maximum limit, not an average: when we say the diameter tolerance is ±0.04 mm, the real numbers are much lower. We continuously measure and record diameter and ovality across the full length of every spool and publish the actual data.
Every Prusament spool comes with the actual measured data from manufacturing: diameter readings along the entire length, weight, and ovality. We're the only filament manufacturer in the world that does this.
Our PLA filament is wound under controlled tension on precision machines. Every spool goes through a final inspection before shipping. The result is a spool that feeds smoothly from start to finish. Also, it looks great every time.
Prusament is manufactured in our facilities in the Czech Republic (Europe) and Delaware (United States). That means faster shipping, lower import duties where applicable, and a supply chain under our full control.
There's no third-party manufacturer who can quietly change a raw material supplier. No surprise batch failures from a factory you've never visited.

Starting October 2025, all Prusament filaments ship on a redesigned spool with a fully rewritable NFC tag powered by the OpenPrintTag standard.
The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app. It works entirely offline, it is free to extend, and open for anyone to build upon.
