The short answerPETG is tougher than PLA and easier than ABS.
PETG is a glycol-modified polyester that bridges PLA and ABS. It prints hotter than PLA, survives heat and impact, and needs no heated chamber. The Prusament and Polymaker datasheets put its nozzle range at 240 to 260 °C.
What PETG is
PETG stands for glycol-modified polyethylene terephthalate. The glycol makes it clearer, tougher, and less brittle than raw PET. It sits between PLA, which is easy but brittle, and ABS, which is tough but hard to print.
Settings at a glance
These ranges come from the Prusament and Polymaker PETG datasheets, with drying guidance from Bambu Lab.
| Setting | Recommended | Why |
|---|---|---|
| Nozzle temperature | 240 to 260 °C | Prusament and Polymaker both land here. |
| Bed temperature | 70 to 80 °C | Prusament lists 80 °C with a 10 °C margin. |
| Part cooling fan | 20 to 60 % | Polymaker range. Start low, raise for overhangs. |
| Print speed | 40 to 60 mm/s | Prusament allows up to 200 mm/s. Slow for detail. |
Where PETG fits
- Pick PETG for functional parts that take a knock.
- Pick PETG for parts that face warmth, but not sustained high heat.
- Skip PETG for pure display models, where PLA is easier and looks crisper.
PETG compared
| Property | PETG | PLA | ABS |
|---|---|---|---|
| Ease of print | Medium | Easy | Hard |
| Heat resistance | Medium | Low | High |
| Toughness | High | Low | High |
| Nozzle temperature | 240 to 260 °C | 200 to 220 °C | 245 to 265 °C |
| Needs a heated chamber | No | No | Yes |
| Best for | Durable parts | Models | Warm, functional parts |
Common PETG problems
| Likely cause | Fix | Severity |
|---|---|---|
| Nozzle too cold | Raise the nozzle 5 °C toward 260 °C | md |
| Bed too cold | Raise the bed to 80 to 90 °C | hi |
| Wet filament | Dry at 60 to 65 °C for 8 hours | hi |
| Fan too high | Drop part cooling to 20 to 40 % | lo |
Key takeaways
- PETG prints at 240 to 260 °C with a 70 to 80 °C bed.
- It is tougher and more heat-resistant than PLA.
- Dry PETG before printing; it absorbs water fast.
- Pick PETG for functional parts, PLA for display models.
