The Creality Ender-3 V3 SE has some key differences from the Ender 3 v2 that will influence the optimal settings for printing 3D Fusion PLA and PETG. The most significant change is the move to a direct drive extruder and the inclusion of auto bed leveling. Here’s how the settings would likely differ:  

Key Differences Affecting Settings:

• Direct Drive Extruder: This is the biggest change. Direct drive extruders have the motor and extruder gears located directly above the hot end. This reduces the distance the filament has to travel, leading to better retraction performance and the ability to print more flexible filaments.  
• Auto Bed Leveling (ABL): The V3 SE features CR Touch or a similar ABL system, which simplifies bed leveling and can compensate for minor imperfections.  
• Potentially Higher Print Speeds: The V3 SE is often marketed with the capability of achieving higher print speeds compared to the V2.  
• Updated Cooling System: The cooling setup on the V3 SE might be different, potentially impacting optimal fan settings.

Updated Settings for 3D Fusion PLA on Creality Ender-3 V3 SE:

• Nozzle Temperature: 200-215°C (Likely remains similar, start with 205°C).
• Bed Temperature: 50-60°C (Likely remains similar, start with 55°C).
• Print Speed:
  • Initial Layer Speed: 15-20 mm/s (Likely remains similar for optimal adhesion).
  • Infill Speed: 60-80 mm/s (The V3 SE might handle higher speeds well).
  • Outer Wall Speed: 30-45 mm/s (Can potentially increase slightly while maintaining quality).
  • Inner Wall Speed: 50-70 mm/s (Potential for higher speeds).
• Retraction: This is a significant change due to the direct drive.
  • Retraction Distance: 0.5-1.5 mm. Direct drive extruders require much shorter retraction distances. Start with 1mm and fine-tune.  
  • Retraction Speed: 25-40 mm/s. You might need to experiment within this range.
• Layer Height: 0.15-0.2 mm (Likely remains similar).
• Infill:
  • Infill Pattern: Gyroid, Cubic, or Grid (Likely remains similar).
  • Infill Density: 15-25% (Likely remains similar).
• Cooling: Enable part cooling fan at 100% after the first few layers (Might need slight adjustment based on the specific cooling setup of the V3 SE – observe overhang performance).
• Bed Adhesion: Skirt is likely sufficient due to ABL. Brim might still be useful for small-footprint prints, but the need is reduced.

Updated Settings for 3D Fusion PETG on Creality Ender-3 V3 SE:

• Nozzle Temperature: 230-245°C (Likely remains similar, start with 235°C).
• Bed Temperature: 70-80°C (Likely remains similar, start with 75°C).
• Print Speed:
  • Initial Layer Speed: 15-20 mm/s (Likely remains similar).
  • Infill Speed: 50-70 mm/s (Potential for higher speeds compared to the V2).
  • Outer Wall Speed: 25-35 mm/s (Might be able to increase slightly).
  • Inner Wall Speed: 40-60 mm/s (Potential for higher speeds).
• Retraction: Significant change due to direct drive.
  • Retraction Distance: 1-2 mm. Start with 1.5mm and fine-tune. PETG still tends to string more than PLA, so careful adjustment is needed.  
  • Retraction Speed: 25-40 mm/s. Experiment to find the sweet spot.
• Layer Height: 0.15-0.25 mm (Likely remains similar).
• Infill:
  • Infill Pattern: Gyroid, Cubic, or Triangles (Likely remains similar).
  • Infill Density: 15-25% (Likely remains similar).
• Cooling: Use part cooling fan sparingly, typically at 30-60%. The direct drive might allow for slightly more cooling compared to the V2, but it still avoids excessive cooling with PETG.
• Bed Adhesion: Brim is often helpful. Glue stick on glass can still be a good release agent.

Important Considerations for the Ender-3 V3 SE:

• Retraction Tuning is Key: The direct drive requires significantly less retraction. Start with lower values and incrementally increase if you see stringing. Too much retraction can cause clogs.
• Take Advantage of Auto Bed Leveling: Ensure your ABL is properly calibrated. While it helps, a generally level bed is still recommended for the best results.
• Experiment with Higher Speeds: The V3 SE is designed for faster printing. Gradually increase speeds to find the optimal balance between speed and quality for your specific needs.  
• Observe Cooling Performance: The cooling system on the V3 SE might be more efficient. Pay attention to overhangs and adjust fan settings accordingly.

Recommendation:

Treat these settings as a starting point. The best approach is to run test prints (like temperature towers and retraction tests) with your specific 3D Fusion filament on your Ender-3 V3 SE to fine-tune the optimal settings for your desired print quality and speed. Happy printing!
