The Creality Ender 3 v2 has solidified its place as a beloved and reliable 3D printer within the maker community. Its affordability and versatility make it an excellent platform for both beginners and experienced enthusiasts. At 3D Fusion, we’re passionate about providing high-quality filament that helps you unlock the full potential of your Ender 3 v2.
This guide will provide you with our recommended starting settings for printing both our popular 3D Fusion PLA and PETG filaments on your Ender 3 v2. While these settings are a great foundation, remember that 3D printing can be a nuanced process, and slight adjustments might be necessary based on your specific printer, environment, and desired outcome.
Understanding Key Slicer Settings
Before we dive into the specifics, let’s quickly recap some of the crucial slicer settings we’ll be discussing:
- Nozzle Temperature: The temperature at which the filament is melted and extruded.
- Bed Temperature: The temperature of the build plate, crucial for first-layer adhesion and preventing warping.
- Print Speed: The speed at which the print head moves during printing. This is often broken down into different speeds for various parts of the print (initial layer, infill, walls).
- Retraction: The process of pulling the filament back into the nozzle when the printer moves between non-printing areas. This helps prevent stringing and blobs.
- Retraction Distance: The amount of filament pulled back.
- Retraction Speed: The speed at which the filament is retracted.
- Layer Height: The thickness of each printed layer. Smaller layer heights result in finer detail but longer print times.
- Infill: The internal structure of your print, affecting its strength and weight.
- Infill Density: The percentage of the print’s interior that is filled with infill.
- Cooling: The use of fans to cool the extruded filament, which is particularly important for PLA.
- Bed Adhesion: Slicer settings that help the first layer stick to the build plate (e.g., brim, skirt, raft).
Best Settings for 3D Fusion PLA on Creality Ender 3 v2
PLA is generally considered an easy-to-print filament, and our 3D Fusion PLA is formulated for smooth and reliable results on the Ender 3 v2. Here are our recommended starting points:
- Nozzle Temperature: 200-215°C. Start with 205°C and adjust slightly based on your specific PLA color and desired surface finish. Higher temperatures can improve layer adhesion but might lead to stringing.
- Bed Temperature: 50-60°C. A heated bed is highly recommended for PLA on the Ender 3 v2. Start with 55°C.
- Print Speed:
- Initial Layer Speed: 15-20 mm/s. A slower initial layer speed helps ensure good adhesion.
- Infill Speed: 50-60 mm/s.
- Outer Wall Speed: 25-35 mm/s. Printing outer walls slower can improve surface quality.
- Inner Wall Speed: 40-50 mm/s.
- Retraction:
- Retraction Distance: 5-6 mm. The Ender 3 v2 with its Bowden setup generally requires a slightly longer retraction distance.
- Retraction Speed: 40-45 mm/s.
- Layer Height: 0.15-0.2 mm. This range offers a good balance between detail and print time. You can go lower for finer details or higher for faster prints.
- Infill:
- Infill Pattern: Gyroid, Cubic, or Grid are popular choices for PLA.
- Infill Density: 15-25% for general-purpose prints. Increase for more strength.
- Cooling: Enable part cooling fan at 100% after the first few layers. PLA benefits significantly from good cooling to prevent warping and improve overhangs.
- Bed Adhesion:
- Brim: Recommended for prints with small footprints or sharp corners to prevent warping. A 5-10 line brim is usually sufficient.
- Skirt: A good option for priming the extruder and ensuring consistent flow before the print starts.
Best Settings for 3D Fusion PETG on Creality Ender 3 v2
PETG offers excellent strength and durability but can be a bit more sensitive to settings than PLA. Here are our recommended starting points for printing 3D Fusion PETG on your Ender 3 v2:
- Nozzle Temperature: 230-245°C. Start with 235°C and adjust based on your specific PETG color. PETG requires higher temperatures than PLA.
- Bed Temperature: 70-80°C. A heated bed is essential for PETG. Start with 75°C.
- Print Speed: Generally, PETG prints better at slightly slower speeds than PLA.
- Initial Layer Speed: 15-20 mm/s.
- Infill Speed: 40-50 mm/s.
- Outer Wall Speed: 20-30 mm/s.
- Inner Wall Speed: 30-40 mm/s.
- Retraction: PETG is prone to stringing, so dialing in retraction is crucial.
- Retraction Distance: 6-7 mm. You might need to experiment slightly with this.
- Retraction Speed: 30-40 mm/s. Lower retraction speeds can sometimes help with PETG.
- Layer Height: 0.15-0.25 mm. Similar to PLA, this range provides a good balance.
- Infill:
- Infill Pattern: Gyroid, Cubic, or Triangles work well with PETG.
- Infill Density: 15-25% for general-purpose prints.
- Cooling: Use part cooling fan sparingly, typically at 20-50%. Excessive cooling can negatively impact layer adhesion with PETG. You might even try printing the first few layers without any fan.
- Bed Adhesion:
- Brim: Often helpful for PETG, especially for larger prints.
- Raft: Can be used for challenging geometries or if you’re having trouble with bed adhesion.
- Glue Stick (as a release agent): Applying a thin layer of water-soluble glue stick to a glass bed can prevent PETG from sticking too strongly and potentially damaging the bed upon removal.

Important Considerations and Tuning
- Filament Variations: Remember that even within our 3D Fusion range, different colors of PLA and PETG might have slightly different optimal temperatures. It’s always a good idea to print a temperature tower to fine-tune the best nozzle temperature for a specific roll.
- Printer Calibration: Ensure your Ender 3 v2 is properly calibrated. This includes accurate bed leveling and calibrating your extruder’s E-steps to ensure the correct amount of filament is being extruded.
- First Layer Calibration: A perfect first layer is crucial for print success. Take the time to fine-tune your Z-offset so that the first layer is slightly squished onto the bed without being too thin or too thick.
- Stringing and Blobs: If you experience stringing with PETG, try increasing the retraction distance or decreasing the nozzle temperature slightly. Blobs might indicate too much extrusion or too slow retraction.
- Bridging and Overhangs: For better bridging performance with PLA, ensure good cooling. PETG generally handles bridging slightly less well than PLA and might require slower speeds and less cooling. For overhangs, adjusting the cooling and speed can help.
Conclusion: Start Here, Experiment Often!
The settings provided in this guide are excellent starting points for printing with 3D Fusion PLA and PETG on your Creality Ender 3 v2. However, the beauty of 3D printing lies in experimentation. Don’t be afraid to make small adjustments to these settings based on your specific needs and the results you’re seeing.
