Why teams choose PETG
A practical step up for functional parts that need toughness and chemical resistance beyond basic PLA.
Strengths
- Better toughness and chemical resistance than typical PLA
- Useful for many functional brackets and covers
- Carbon-fibre variants available for stiffer needs

Colour representation is approximate. Material batch, surface finish, print orientation, geometry, lighting and display calibration can affect final appearance.
Colour is subordinate to material choice
Use the variant panel above for swatches. Colours never get standalone pages.

Designing for PETG
Pair with FORM3D Design Guidelines for shared FDM rules.
- Allow clearance for mating assemblies — PETG can be less “dry” than PLA.
- Avoid extremely thin unsupported walls on large spans.
- For CF grades, expect a stiffer, more abrasive composite finish.
Know the trade-offs
- Can string or show surface artefacts on complex geometry
- Not the strongest outdoor UV answer versus ASA
- Heat resistance is moderate, not polycarbonate-class
