3D Printing Material Guide - How to Print PETG with Anet ET4 Series 3D Printer

For those Anet 3D printer users who become accustomed to print with PLA, they may doubt if the Anet ET4 and ET5 series 3D printer can print PETG filament; And if it can, then how to set printing parameters becomes another question. Today, we’ll learn how to set printing parameters on printer and slicer to print PETG on Anet ET4 and ET5 series 3D printers.

I - Get the Right Printing Temperatures on Printer

To print PETG with higher strength (than PLA), we need to set higher temperature for both the nozzle and the hotbed to ensure a better melt and deposit result for the material.

Recommended temperature settings for PETG:

Nozzle temperature: 230℃-250℃
Hotbed temperature: 70℃–75℃.
Fan: OFF or lower speed

As we see from above values, to print PETG, we need higher temperatures. And these temperatures offset within 20℃. That’s because different PETG filaments from different manufacturers or even from the same manufacturer of different colors or different production dates may have different features.  So the printing temperatures vary accordingly.

To get the right printing temperatures for specific PETG filament, we need to print below temperature tower with the PETG filament to measure out the exact values.

Tips: When printing the tower, set the parameters according to the recommendation in the link and use appropriate slicer to do it.

By printing the tower, we get more accurate temperature settings for the nozzle and the hotbed; but still we need to avoid setting the hotbed temperature lower than 70℃ to prevent warping or the printed object striping off from the bed. If we set the bed temperature among 65-70according to the test result of temp tower printing, then we should apply some glue or tape onto the bed to prevent unexpected print failures.

Additionally, don’t forget to set the fan off or operate at lower speed.

Now, let’s see how we can adjust parameter settings for PETG printing on slicer software.


II – PETG Print Settings on Cura

  1. Layer height: 0.06mm - 0.1mm
  2. Infill: 10-20%
  3. Nozzle temperature: 230-250℃
  4. Heat bed temperature: 70-75
  5. Retraction: enabled
  6. Fan: OFF or lower speed
  7. Initial layer print speed: 25mm/s


When print with PETG, we should adjust some parameters on slicing software accordingly. Here we take Cura as an example. 

  1. Set layer height at 0.06mm; if want to speed up the printing, this value can be increased a little but not higher than 0.1mm.
  2. Infill value can adjust according to your requirement.
  3. For high speed printing, set infill to 10% or lower
  4. For delicate components printing, set infill to 20%
  5. For tool printing, set infill to 100% for reliabilities.
  6. Adjust both nozzle and hotbed temperature according to temp tower print result; as we tested, hotbed temperature should be set among 70℃-75℃.
  7. Enable retraction and set retraction distance at 7 to avoid oozing.
  8. When set hotbed temperature to below 70℃ according to temp tower printing, we can apply some glue or tape onto the hotbed, or set adhesion type to raft to enhance first layer addition and easy removal of the printed model.
  9. And as mention in previous paragraph, find the “Cooling” option in slicer settings and set the fan off or operate at lower speed to further ensure high temperature needed for PETG printing. “Cooling” setting can also be adjusted while printing.enable cooling on cura
  10. Another important factor for PETG printing is the “Initial Layer Speed” setting. According to our test, the default value on Cura (see below picture) fits PETG printing. No change should be done here.

Follow above guidance and adjust the print settings, and then we can print PETG with Anet ET series 3D printer very well.

Ok, that’s all the content about PETG printing on Anet ET series 3D printer. Actually we only need to find out the accurate printing temperatures (commonly higher than PLA printing) for specific PETG filament, and then adjust temperature and some other settings according to the guidance. It’s quite easy, isn’t it?

Wish you a happy PETG printing with Anet ET series 3D printer!
