Choose PETG when you need a versatile functional part and PLA isn't durable enough.
Best for
- brackets and assembly parts
- covers and functional parts
- parts exposed to moisture
Strengths
- good toughness
- moisture resistance
- wide practical use
What to consider
- higher tendency to string
- less sharp detail than PLA
- surface can be glossier
Advantages and limitations
Exact print settings may vary by printer, nozzle and part geometry. We'll send the technical data sheet (TDS) on request.

Printing tips
On smooth PEI or glass, we recommend using a release layer.
These values are indicative, for a 0.20 mm layer height and a 0.4 mm nozzle (0.6 mm for CF and GF). Start with the baseline setting and fine-tune it for your printer — maximum speed can be limited by hotend flow rate. The cooling fan value in the table refers to the part-cooling fan; print the first 2 layers without cooling, overhangs and bridges may need more. Leave the hotend cooling fan at your printer manufacturer's default setting. Dry the filament in a temperature-controlled dryer, don't exceed the spool's heat resistance, and after drying store it sealed with a desiccant.

Questions about PETG
What is PETG filament suitable for?
PETG combines relatively easy printing with higher toughness and durability. It suits brackets, covers and parts for everyday technical use.
Is PETG suitable for outdoor use?
PETG is best suited for indoor use. For parts permanently exposed to sunlight and weather, choose ASA.
What diameter and tolerance does 3DFINITY PETG filament have?
PETG filament is manufactured at a 1.75 mm diameter with a declared tolerance of ±0.02 mm. We make it using our own technology in Slovakia with diameter control during production.
