What Are the Optimal Settings for eSUN PETG?

The unique properties of the plastic used in different filament types play a vital role in the configuration of the print settings, as each difference in attributes that directly affect the printing process, such as the melting point, also requires you to configure your printing parameter correspondingly.

On the other hand, even though not as considerable as the differences between different types of filament, it’s also possible to see differences in optimal print settings between different brands due to the fact the manufacturing process and the composition of materials that each manufacturer uses are distinct.

In today’s article, we will be analyzing the optimal print settings for the eSUN brand of PETG filament through the manufacturer’s recommendations, which will provide a quick and straightforward optimization that will improve the quality of your prints compared to using generic PETG settings.

So, what are the optimal print settings for eSun PETG filament?

  • Nozzle (Print) Temperature – 230 to 250 degrees Celsius
  • Bed Temperature – 60 to 80 degrees Celsius
  • Print Speed – 60 to 100 millimeters per second
  • Filament Diameter – 1.75 mm or 2.85 mm

Moving forward, we will be talking about configuring print settings as optimally as possible for eSUN PETG in greater detail, finding out how to save these settings in Cura and PrusaSlicer, and finally, taking a quick look at the optimal eSUN PETG settings specifically for the Ender 3.

What Are the Optimal Settings for eSUN PETG?

While the base material is the primary factor determining the characteristics affecting the print settings that you will need to use, the fact that each manufacturer uses a different material composition for their filament also plays a role that we cannot ignore. 

According to the manufacturer, a nozzle temperature range of 230 to 250 degrees Celsius, a print speed range of 60 to 100 millimeters per second, and a bed temperature of 60 to 80 degrees Celsius are optimal for printing with eSUN PETG.

Since you can find eSUN PETG both with 1.75 millimeters and 2.85 millimeters of filament diameter, it’s vital to ensure that the variant you pick is supported by your 3D printer (1.75 mm is virtually the standard) and that you have configured your slicer to match the filament diameter value accordingly.

For the best results, remember to conduct test prints with distinct values that fall in the ranges the manufacturer recommends (such as by incrementing or decrementing the print temperature by five at a time), compare the results you have gathered, and perform adjustments accordingly.

How to Save eSUN PETG Settings in Cura?

As saving your customized settings will grant much more comfortable access whenever you want to switch between different filaments, it’s something we highly recommend doing once you are done with the configuration process.

Below, you can find a quick step-by-step guide for adding eSUN PETG as a custom material in Cura:

  1. Click the Prepare tab on the top of the Cura window.
  2. Click the middle pane to bring up the settings related to the material and the nozzle size.
  3. Click the Material dropdown, and click Manage Materials.
  4. Click Generic PETG from the list on the left, and click the Duplicate button to create a new material profile with the base PETG settings.
  5. Choose the new entry from the list to make editing possible.
  6. Type eSUN into the Brand input and 1.75 mm (or 2.85 mm) into the Diameter input.
  7. Click the Print Settings tab.
  8. Fill in the configuration that belongs to the filament, such as the print temperature, into the appropriate inputs.

While that will save eSUN PETG as a material that you can choose, saving material-specific settings such as the print temperature and the filament diameter, you will also need to create a custom print setting profile for any non-material configuration that you would like to use in conjunction, such as print speed. 

Here is how you can add the print settings you will be using with eSUN PETG as a custom print profile in Cura:

  1. Go to the Prepare tab in Cura.
  2. Click the right pane to bring up the print settings.
  3. Click the Custom button if visible; else, skip this step.
  4. Click the Profile dropdown menu, and select Manage Profiles from the list.
  5. Duplicate one of the readily available profiles, and name the new profile eSUN PETG.
  6. Activate the profile by clicking the Activate button.
  7. Make the adjustments you wish to use with eSUN PETG, such as changing the print speed through the print settings area.
  8. Click the Profile dropdown menu, and choose the “Update profile with current settings/overrides” button to save all the adjustments you have performed to the profile you have made.

After getting the custom material and the custom profile ready, you can activate them from their corresponding sections whenever required, which will tell Cura to load both the material-specific and non-material-specific settings you have specified for usage.

How to Add eSUN PETG Settings into PrusaSlicer?

The PrusaSlicer preset feature exists to add custom settings that you can reload for any specific scenario of your choice, which is what we will be using to add the unique set of configurations for eSUN PETG.

Below is our step-by-step guide that you can follow to add eSUN PETG as a preset in PrusaSlicer:

  1. Navigate to the Filament Settings Section of PrusaSlicer.
  2. Click the Save button (floppy disk icon).
  3. Type eSUN PETG into the box to determine the preset’s name.
  4. Modify the parameters such as Filament Diameter, Filament Density, Filament Cost, Spool Weight, Nozzle Temperature, and Bed Temperature accordingly.
  5. Click the Save button once more, this time to finalize the changes.
  6. Directly click the OK button without making any changes to the name of the preset, which will transfer the configuration you have adjusted to the preset you have created.

After saving the custom preset, you can find it in the Filament dropdown menu under the Plater tab of PrusaSlicer with the name that you have specified during the saving process, and reload the settings whenever required by clicking the entry.

What Are the Optimal eSUN PETG Settings for Ender 3 (Pro/V2)?

Due to many 3D printing enthusiasts looking to find settings optimized explicitly for the Ender 3, as it’s the most-used 3D printer on the market right now, let’s quickly go through the Ender 3 optimized settings for eSUN PETG in this section.

Below, you can find our recommended eSUN PETG settings for the Ender 3, which provided optimal results for us:

  • Nozzle Temperature – 245 degrees Celsius
  • Bed Temperature – 80 degrees Celsius
  • Print Speed – 60 millimeters per second
  • Filament Diameter – 1.75 mm

Feel free to conduct test prints to find the values that will work best for you, as the values we have shared are results of our own tests and may not work equally well in every scenario. 

Wrapping Up

Utilizing the manufacturer’s recommendations for the brand of filament that you are using and saving the settings for later use is one of the most efficient optimizations you can perform, as the print quality will highly benefit from it for a fraction of your time.

To quickly recap, a range of 230-250 for the print temperature, 60-80 for the build platform temperature, 60-100 mm/s for the print speed, and finally, 1.75 mm (or 2.85 mm, depending on the variant you have) for the filament diameter are the suggested values for printing with eSUN PETG.

Since the values provided by the manufacturer are ranges rather than exact numbers, finding the precise figures that will work best in your case will require you to slowly narrow the ranges down by running test prints with distinct values for the parameters and making adjustments according to the results.

Happy printing!
