PETG (Polyethylene Terephthalate Glycol) is one of the most-used 3D printing materials. In plain terms: the durable all-rounder — strong, tough and food-safe grade.
VOXFIL PETG combines the strength of ABS with PLA-level printability. It resists chemicals and moisture, handles impacts without shattering, and prints with a smooth, glossy surface. The go-to material for functional parts that live in the real world.

How to print PETG
- Nozzle: 230 – 250 °C (240 °C sweet spot)
- Bed: 70 – 85 °C, PEI recommended
- Speed: 40 – 90 mm/s, low cooling
- Retraction tuning avoids stringing — see our guide
