About PETG

PETG is one of the most commonly used filaments. Its strength and durability make it an excellent choice for printing various mechanically-stressed parts, such as various holders, or clamps, for example. Due to its excellent layer-to-layer adhesion, PETG prints are ideal for indoor and outdoor waterproof applications. Furthermore, PETG is a tough material with good high-temperature resistance. The G in the acronym stands for a glycol-modified substance that is present during the manufacturing process. It modifies the properties of PET, so that it’s easier to print, less brittle, and clearer when printing with semi-transparent variants. PETG has a low thermal expansion, so even when printing big objects, and without an enclosure, it rarely lifts from the bed and warps. In addition to that, PETG is tougher and less brittle than PLA. It has a healthy amount of flex which can prevent parts from breaking under pressure. We use PETG to print parts for our printers!

Printing Setup

• Nozzle - 250 ±10 °C
• Heatbed - 80 ±10 °C
• Recommended Steel Sheet - Textured / Satin

Check Prusa's material table and print-surface preparation instructions before starting.

Basic Attributes

• Good high-temperature resistance - Worse details than PLA, for example
• Easy to print - Possibility of stringing
• Low shrinking and warping - Poor bridging characteristics
• High strength and durability
• Easier to sand than PLA (softer, less melting)

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.

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.

Prusament is produced by Prusa Polymers, with manufacturing checks throughout 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.

Prusa specifies a filament diameter tolerance of ±0.02 mm. Check the product notes for blend-specific tolerances.

The spool's QR code gives access to its recorded production parameters.

Beginners tips & tricks

Unlike PLA or ABS, PETG tends to ooze a bit and may leave strings of plastic on your print. We suggest drying the filament before printing, as described here. If stringing still occurs, you may further counter it by increasing retraction and playing with hotend temperature, but if you use our filament presets in Prusa Slicer, we already did that for you and the amount of stringing should be minimal. Or, you can get rid of the strings by briefly blasting your finished prints with a heat gun.

Notes This PETG is made in-house by Prusa Research. 1.75 mm filament is manufactured with precision of +- 0.02 mm Before printing, make sure the surface of heatbed is clean as described in 3D Printing Handbook. If you choose a 2 kg spool, please download and print the 2kg spool holder as it will not fit the standard spool holder. To dry the filament, please follow the instructions in our article.
