As each type of filament has unique properties, settings such as nozzle temperature, bed temperature, and many more require adjustments between different filament types for the printing process to succeed and create the optimal final product.
Alongside this, it’s also worth considering that the difference in the manufacturing process and material composition among different brands of filament also change the optimal configuration, making using brand-specific settings a significant point of improvement.
In today’s article, we will take a deep look into the optimal settings for Sunlu PETG, which will allow us to obtain better results than what we can achieve with generic PETG settings, as generic settings aren’t as optimized as brand-specific settings.
So, what are the optimal settings for Sunlu PETG?
We have listed the optimal settings for Sunlu PETG below, taken directly from the manufacturer’s website:
- Nozzle (Print) Temperature – 220 to 250 degrees Celsius
- Bed Temperature – 60 to 80 degrees Celsius
- Print Speed – 50 to 100 millimeters per second
- Filament Diameter – 1.75 mm
In the upcoming sections, we will analyze the optimal settings for Sunlu PETG in greater detail and go over the steps we recommend taking to add these settings to popular slicer software such as Cura and PrusaSlicer.
What Are the Optimal Settings for Sunlu PETG?
Even though they consist of the same base material, the optimal settings for different brands of filaments can show a degree of variance due to each manufacturer using a distinct manufacturing process and material composition for their spools of PETG filament.
Sunlu recommends a nozzle temperature that falls into the range of 220 and 250 degrees Celsius and a bed temperature that falls into the range of 60 and 80 degrees Celsius for an optimal printing process with the Sunlu PETG.
Aside from the temperature values, the recommended print speed value by the manufacturer is between 50 and 100 millimeters per second, and the filament has a diameter of 1.75 mm, which is a vital piece of configuration that your slicer requires.
As the configuration values recommended by Sunlu are ranges rather than direct values, finding the optimal numbers for your printer can require a few test prints of experimenting with different values, which we highly recommend doing.
As an example, for this article, we have tested a spool of Sunlu PETG with an Ender 3 printer, where we have found the value of 235 degrees Celsius to be optimal for nozzle temperature, 70 degrees Celsius for bed temperature, and 80 millimeters per second for print speed.
How to Configure Sunlu PETG Settings in Cura?
While it’s possible to enter the parameters manually to configure Cura for printing with Sunlu PETG, this process can become tedious for those who frequently switch between different brands and types of filament.
Fortunately, it’s possible to store settings for specific filaments in Cura and load them back whenever you need, making the process of switching between filaments much easier.
To start, let’s take a look at the process of adding custom material presets to Cura, where we can save a set of configurations that are specific for Sunlu PETG:
- Click the Prepare tab located on the top of the Cura window.
- Click the pane on the middle, which should have information about the current material and nozzle size.
- Click the dropdown that corresponds to the Material label.
- Choose the Manage Materials option from the dropdown menu.
- Choose the Generic PETG entry from the left pane, and click the Duplicate button.
- Choose the newly duplicated entry from the left pane.
- Fill the Brand Box with Sunluand the Diameter box with 1.75.
- Switch to the Print Settings tab in the same window.
- Fill the values you would like to use specifically with Sunlu PETG filament into their respective inputs.
Upon successfully adding the custom material, you can find the Sunlu PETG option in the Material drop down and activate the specific settings by clicking this option.
After adding Sunlu PETG as a custom material and activating it, let’s also configure a custom profile that contains the print settings we will use for Sunlu PETG in specific.
- Click the Prepare tab on the Cura window.
- Click the pane on the right, which displays the print settings information.
- Click the Custom button if you haven’t switched to Custom mode already.
- Click the Profile dropdown, and choose the Manage Profiles option.
- Duplicate a default profile by selecting one from the left pane and clicking the Duplicate button.
- Give your new profile a name, such as Sunlu PETG, to make it easy to find.
- Activate the profile by selecting it from the left pane and clicking the Activate button.
- Modify the Print Settings you would like to save on this profile.
- Click the Profile dropdown, and choose the “Update profile with current settings/overrides” option to save the settings into the profile.
Once you create both the custom material and the custom profile, all there is left to do is select the Sunlu PETG material from the material dropdown and the corresponding profile from the profile dropdown in the Print Settings section, which will activate all of your Sunlu PETG settings.
How to Configure Sunlu PETG Settings in PrusaSlicer?
As PrusaSlicer also allows adding custom material presets, adding all the filaments you regularly use into PrusaSlicer will make the printing process much more convenient.
In the case of adding Sunlu PETG as a custom preset in PrusaSlicer, here are the steps we recommend following to get the process done as effortlessly as possible:
- Click the Filament Settings tab, which you can find on the top of the PrusaSlicer window.
- Click on the Floppy Disk icon next to the Filament dropdown, which you can find at the top left corner of the window.
- Type Sunlu PETG into the input to give the custom preset a meaningful name that you can easily find later.
- Modify the Nozzle Temperature, Bed Temperature, and Filament Diameter with the manufacturer’s suggestions. Optionally, you can fill out the Filament Cost, Filament Density, and Spool weight inputs to allow PrusaSlicer to calculate your filament usage.
- Click the Save button, and save the preset without modifying the name this time to write the settings into the Sunlu PETG preset you have created in step 3.
Once you successfully add the preset, you will be able to find Sunlu PETG in the Filament dropdown, which you can locate in the Plater tab of PrusaSlicer, and activate the specific settings you have saved earlier with the click of a button.
Creating custom profiles with the information you obtain from the filament manufacturer’s recommendation is, without a doubt, the best way to ensure that you always use the optimal settings for the filament you’re using and leave no room for error in configuration.
To quickly recap, let’s quickly mention the optimal settings for Sunlu PETG that we have directly taken from the manufacturer’s website:
- Extruder Temperature – 220-250°C
- Platform Temperature – 60-80°C
- Print Speed – 50-100 mm/s
- Filament Diameter – 1.75 mm
To find the most optimal configuration for your printer, we highly recommend running some test prints by incrementally increasing or decreasing the values while staying in the range the manufacturer recommends.
