How to print with Ultimaker PETG

PETG is a glycol modified version of Polyethylene Terephthalate (PET). It has the same reliable printability as PLA, but with enhanced toughness, chemical resistance, wear resistance, and temperature resistance (up to 75°C). It is therefore the go-to material for 3D printing in industrial environments for functional prototypes and manufacturing aids.

Note: The information provided here applies to Ultimaker PETG, similar quality cannot be guaranteed with third-party filaments.

Tip:  Ultimaker Cura version 4.9.1 onwards contains optimized print profiles for Ultimaker PETG and can be downloaded here.

Ultimaker PETG can be printed on the Ultimaker S5, Ultimaker S3 and Ultimaker 3 using an AA print core, and on the Ultimaker 2+ Connect printers . On other Ultimaker 3D printers, you may use this material experimentally, although no official print profiles are supplied. The best way to use PETG on the Ultimaker 2(+) is by selecting CPE as the base profile and adjust the print temperature to 245°C and the build plate temperature to 85°C. Read more how to make custom materials for the Ultimaker 2(+) on this page.

Printer Compatible print cores / nozzles
Ultimaker S5 (Pro Bundle) AA 0.25, AA 0.4, AA 0.8
Ultimaker S3

AA 0.25, AA 0.4, AA 0.8

Ultimaker 3

AA 0.25, AA 0.4, AA 0.8

Ultimaker 2+ Connect

0.25, 0.4, 0.6, 0.8


Ultimaker PETG has optimized settings for the Ultimaker S5 Pro Bundle, Air Manager, and Material Station. This ensures a good end of filament and end of print experience in the Material Station and an optimal build environment with the Air Manager. Please make sure to use the latest version of Ultimaker Cura and ensure the firmware has the latest update.

PETG can also be used for dual-extrusion prints, in combination with PVA, Breakaway, or another color of PETG. Below you can find the complete compatibility overview for PETG.

The experimental (exp) and not supported (X) combinations have not been verified, since limited use cases are available. Results are dependent on the model type that is used. Combinations with Ultimaker TPU95A are experimental, because of the potential oozing of TPU95A in dual prints.

Recommended settings and configuration

Note:  Always use the latest version of Ultimaker Cura and make sure that your 3D printer is updated with the latest firmware version to include the correct material profile for Ultimaker PETG. PETG profiles can be found in Cura 4.9.1 or higher.


PETG prints at nozzle temperatures between 225°C and 245°C. Depending on the selected profile in Ultimaker Cura there are small differences in the nozzle temperatures. These have been optimized to print properly with the selected print core size and layer height profile. The build plate temperature is set to 85 °C for reliable adhesion. These temperatures are the same for the Ultimaker S5, Ultimaker S3, and Ultimaker 2+ Connect.

PETG also supports intent print profiles, where the visual print profiles focus on reduced stringing and optimal overhangs and the engineering print profiles focus on enhanced Z strength.

Note: The correct temperatures are automatically used based on the printer, nozzle size, and profile you select in Ultimaker Cura.


For reliable adhesion and to reduce the chance of glass plate chipping, a thin layer of UHU glue (included in the accessory box of your 3D printer) should be applied to the glass plate. Printing with Ultimaker PETG doesn’t require any additional accessories.


Caution:  The addition of glue is recommended to improve adhesion and thereby prevent the chance of print failure and printer damage. Additionally, the use of glue can prevent overadhesion that can lead to damage to the build plate.

In Ultimaker Cura the default build plate adhesion type for all PETG profiles is with a brim. This enables even large models to adhere well to the build plate.

Print environment

PETG is an easy-to-print material and therefore does not require additional accessories to create a stable printing environment.

Health and safety

Ultimaker PETG emits low levels of gases and particles when 3D printed in accordance with the recommended temperatures mentioned above. To ensure a comfortable and healthy working environment, we recommend 3D printing in a well-ventilated area.
