Polyethylene terephthalate glycol
PETG 3D printing service
PETG is the workhorse for functional parts. It is tougher and more heat tolerant than PLA, handles moisture and many household chemicals, and flexes a little before it breaks instead of snapping.

Fit for purpose
Where PETG works, and where it doesn't.
Good for
- Brackets, mounts, and mechanical parts
- Parts exposed to water or humidity
- Snap fits and parts that need some give
- Outdoor parts that stay out of long direct sun
Properties
- Good impact resistance and layer adhesion
- Heat tolerance to roughly 70–80 °C
- Resists moisture and many common chemicals
Things to consider
- Slightly less crisp detail than PLA
- Degrades over years of UV exposure; ASA is better for permanent outdoor use
