The short answerRun PETG hot, and keep the bed warm.
A PETG nozzle sits between 240 and 260 °C, and the bed lands near 80 °C. The Prusament and Polymaker datasheets set those bands. Start in the middle and tune for stringing or warping.
The nozzle range
PETG melts higher than PLA. The Prusament PETG datasheet lists 250 °C with a 10 °C margin, and the Polymaker PETG sheet lists 240 to 260 °C. Stay inside that band. Below 240 °C the layers bond weakly. Above 260 °C the filament strings and oozes.
| Setting | Recommended | Why |
|---|---|---|
| Nozzle temperature | 240 to 260 °C | Prusament 250 ±10, Polymaker 240 to 260. |
| Bed temperature | 70 to 80 °C | Prusament lists 80 °C with a 10 °C margin. |
| Part cooling fan | 20 to 60 % | Keep fan low for the first layers. |
| Print speed | 40 to 60 mm/s | Slow down for clean corners. |
Bed temperature
Prusament sets the PETG bed at 80 °C with a 10 °C margin. Polymaker lists 60 to 70 °C for the build plate. A bed of 70 to 80 °C sits inside both. Drop to 60 °C if the part prints too hot and lifts at the center.
Tuning for common flaws
| Likely cause | Fix | Severity |
|---|---|---|
| Stringing between moves | Drop the nozzle 5 °C and add retraction | md |
| Corners lifting | Raise the bed to 80 to 90 °C and clean the sheet | hi |
| Weak layer adhesion | Raise the nozzle 5 °C toward 260 °C | md |
| Rough top surface | Slow the print speed to 40 mm/s | lo |
Key takeaways
- Print PETG at 240 to 260 °C on the nozzle.
- Set the bed to 70 to 80 °C, or up to 90 °C if corners lift.
- Keep the part cooling fan between 20 and 60 %.
- Dry wet PETG before you blame the temperature.

Do I need a temperature tower for PETG?
For the full settings set, read the PETG temperature guide. For the broader material overview, see the PETG filament page. Stringing that does not clear with temperature usually needs the PETG retraction settings.
