Printing PETG Filament on Ender 3: Tips and Settings

Printing with PETG (or pet G) filament on your Ender 3 can yield fantastic results, but it requires specific settings and considerations. In this Filament Friday blog post, we will explore the nuances of printing with PETG, review recommended temperatures, discuss the impact of PTFE tubing, and showcase prints using Atomic and Prusament filaments.

Understanding Temperature Requirements

PETG filament typically requires higher temperatures compared to PLA. Both Atomic and Prusament filaments suggest a printing temperature range of 240 to 265 degrees Celsius. It is crucial to note that the lower end of this range should be considered as the minimum for successful prints.

The Role of PTFE Tubing

The standard PTFE tubing that comes with the Ender 3 can pose challenges when printing PETG at higher temperatures. Variability in the quality of this tubing can lead to issues like breakdown, crystallization, or discoloration around 230-240 degrees Celsius. To mitigate these risks, upgrading to a higher temperature PTFE tubing, such as Capricorn tubing, can provide more consistent performance at temperatures up to 260-265 degrees Celsius.

Testing with Atomic and Prusament Filaments

Atomic Filaments Carbon Fiber Black PETG

The Atomic filament in carbon fiber black offers a temperature range of 240 to 265 degrees Celsius. When printed using recommended settings like a 0.2mm layer height, 25% infill, and a nozzle temperature of 240 degrees Celsius, the results are impressive. While PETG prints may appear slightly rougher than PLA, the overall quality is commendable.

Prusament Neon Green PETG

Prusament's neon green PETG filament, with a temperature range of 250 degrees Celsius plus or minus 10 degrees, produces stunning prints. The neon green hue provides a smooth finish, making it an excellent choice for vibrant and visually appealing 3D prints.

Printing Tests: Benchy, Marvin, and Vase Model

Using the recommended settings and slight adjustments in temperature, the Benchy and Marvin prints with both filaments showcase the capabilities of PETG. Additionally, experimenting with vase mode, specifically using a spiralize mode in Cura, allows for the creation of unique, single-walled prints that highlight the filament's characteristics effectively.

Conclusion

Printing PETG filament successfully on an Ender 3 involves understanding temperature requirements, optimizing settings, and potentially upgrading PTFE tubing for consistent results. By following tailored settings and selecting high-quality filaments like Atomic and Prusament, users can achieve remarkable prints with PETG.
