What can you expect?
Prusament PETG is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.02mm precision and highly-consistent colors. You can inspect parameters of every spool we made at prusament.com. Check the sample spool!
Manufactured In-House By Josef Prusa
We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.
Premium-Grade Materials And Thorough Testing
The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.
± 0.02 mm Manufacturing Guaranteed Precision
We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.02mm precision and highly-consistent colors in our filaments.
High Quality You Can Check Yourself
We are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool).
More about PETG Carbon Fiber
Prusament PETG Carbon Fiber is our classic Prusament PETG filament reinforced with carbon fiber, which improves some of its mechanical properties and gives it an attractive look. Compared to regular Prusament PETG, this material has better dimensional stability, better temperature resistance, higher modulus of elasticity, and is less prone to stringing. With Prusament PETG Carbon Fiber, you get very durable, professional-looking prints. The carbon fibers inside the filament are obtained by recycling industrial waste from the production process or carbon composites at the end of their life.

Basic Attributes
New spools equipped with OpenPrintTag
Prusament filaments are wound on a redesigned spool that introduces several improvements for an even better printing experience, starting in October 2025. The new spool features a simple locking mechanism that makes disassembly quick and easy, allowing effortless refills. It also stays secure during filament drying, even at higher temperatures. And with its slimmer dimensions, the spool ensures compatibility with a wide range of multi-color and multi-material printing systems.
Every new Prusament spool now comes with a fully rewritable NFC tag powered by the OpenPrintTag standard. It’s designed to work across brands and ecosystems. It is free to use, free to extend, and open for anyone to build upon. Most importantly, it works entirely offline. All essential data is stored directly on the tag. Your printer can recognize the spool instantly, with no dependence on cloud services or vendor lock-ins. The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app.

Beginners tips & tricks
Make sure you print Prusament PETG Carbon Fiber with a hardened nozzle. Carbon fibers inside are highly abrasive and may damage a regular brass nozzle.
Notes
This PETG Carbon Fiber was made in-house at Prusa Research.
This 1.75mm filament has a manufacturing tolerance of ± 0.02 mm.
Before printing, make sure the surface of heatbed is clean as described in 3D Printing Handbook.
To dry the filament, please follow the instructions in our article.
