PETG print settings

The practical middle ground: tougher and more heat-tolerant than PLA, far easier than ABS.

Enclosure: Works open, but an enclosure improves layer bonding and cuts warping.

Bed surface & adhesion

Bonds far too well to bare PEI and glass — use a glue stick as a release layer or it can tear a chunk out of the sheet.

Retraction starting points

Prone to stringing — favour the higher distance, raise travel speed, and dry the filament if it has absorbed moisture.

Good for

• Functional parts, enclosures, brackets
• Outdoor use — decent UV and moisture resistance
• Anything that needs to flex without snapping

Watch out for

• Strings badly — dry it, raise travel speed, enable combing
• Too much cooling makes layers delaminate; keep the fan low
• Absorbs moisture from the air within days of opening

These are widely-published starting points for the generic material, not a specification. Individual spools vary by brand, colour and additive package — always defer to the figures printed on your spool.
