About PETG
What is PETG?
PETG is what you reach for when PLA isn't robust enough but you don't want the warp and odour of ABS. It is the same chemistry as the bottles your beverages ship in — glycol-modified PET — and it brings impact resistance, mild flex, UV tolerance and food-contact-grade certifications (filament-dependent) to the FDM table. Slight stringing and minor dimensional drift are the trade-offs.
Properties
Spec sheet- Density
- 1.27 g/cm³
- Max use temp
- ~70 °C
- Tensile strength
- ~50 MPa, higher impact than PLA
- Layer adhesion
- Excellent — almost no de-lamination
- Finish quality
- Glossy, slightly translucent
- Indoor / outdoor
- Indoor + light outdoor
- Food-safe
- Food-contact-safe with certified filament + sealed surface
Best for
- Containers, bottles and storage jars
- Lamp shades and light-diffusing fixtures
- Light outdoor signage, planters, garden brackets
- Gadget cases, headphone parts, accessory housings
- Mechanical parts that need impact tolerance, not stiffness
Avoid for
- Tightly toleranced dimensional parts — PETG warps slightly
- Glass-clear optical parts (use resin instead)

Common questions
Questions buyers ask
Is PETG actually food-safe?
The polymer is. The print process introduces microscopic gaps between layers that can trap bacteria. For food-contact use we print with certified food-grade PETG and seal the surface with a food-safe epoxy.
PLA vs PETG — which should I pick?
Pick PLA for decor, prototypes and bright colour. Pick PETG for anything that will be dropped, used outdoors, or hold a liquid.
Will PETG survive an Indian monsoon?
Yes. PETG is stable in humidity and rain, and tolerates UV better than PLA or ABS. We use it for our own outdoor signage.
