What is PETG used for?
Functional parts, brackets, containers, limited outdoor use, watertight parts
+ Pros
Tough, chemical and moisture resistant, easier than ABS/ASA, little warping
– Cons
Prone to stringing, sticks strongly to PEI (use release agent), scratches more easily
Printing tips at a glance
- Nozzle temperature: 230–270 °C – start in the middle of the range on a new spool and fine-tune with a temperature tower.
- Bed temperature: 60–80 °C.
- An enclosure is not needed, but avoid drafts.
- Drying: 65 °C, 6–8 h. Wet filament shows up as crackling, stringing and rough surfaces.

Frequently asked questions
What nozzle temperature does PETG need?
Guideline for PETG: 230–270 °C nozzle and 60–80 °C bed temperature. The exact values are printed on the manufacturer's spool.
How heat resistant is PETG?
Heat deflection temperature (HDT) is around 69–78 °C. Above that, loaded parts start to deform.
Does PETG need to be dried?
Recommended: 65 °C, 6–8 h.
Do I need an enclosure for PETG?
An enclosure is not needed, but avoid drafts.
Values are guidelines from manufacturer datasheets (Polymaker, Bambu Lab, Prusa). They may differ by manufacturer, colour and print settings.
