PETG Filament tips

PET & PETG filament are known for easy printability, smooth finish and water resistance. PETG is a modified version of PET, which is best known for its PET bottles. It is a semi-rigid material with good impact strength. With a slightly soft surface which makes it prone to wear. It also has good thermal properties, so you can cool it well without being afraid of warping.


Shiny and smooth surface finish.

Good bed adhesion with minimal warping.

Usually odorless during 3D printing.


Difficulty printing bridge structures.

Chance of stringing.

Hardware requirements.

Before you buy PETG filament. It is advisable to check whether your 3D printer has the correct hardware. So that you too can achieve optimum print quality with PETG filament.


Heated bed is recommended.

Temperature: 75-90 °C

Closed printer is not necessary.

Construction area

painters tape



Temperature: 230-250 °C.
No special hot end needed.


Fan is necessary.

Pro Tips.

The glossy surface of PETG is especially useful when using a raft. The part separates easily from the raft and maintains a nice surface finish.

Try turning off the fan for the first few layers of the PCB to avoid warping. This trick works especially well for larger prints.

PETG filament 3D printing tips.

With these tips you can reduce the most common problems when printing with PETG filament.

Invest in a good building surface.

Some 3D printers have a glass print bed as standard, or painters tape on the print bed. These surfaces can work fine for PETG. Nevertheless, we recommend a heated print bed for the best result. Especially the first layer adhesion is a lot better from a heated print bed. By laying down a good foundation, the entire print will of course be better. When using a heated glass print bed, additional adhesives are not necessarily required.

Correct retraction settings prevent stringing.

Stringing is a common problem when printing with PETG filament. Stringing is a kind of spider web like threading between parts of your print. Correct retraction distance and speed reduced the chance of stringing.
