3D PRINTING TROUBLESHOOTING

This issue often affects Coral Sponge templates when printing thin walls, resulting in visible gaps and instability.

The problem stems from slicer logic (notably in Bambu Studio and Orca Slicer), where transitions from 2-perimeter to 1-perimeter walls are mishandled. Instead of building a full perimeter and adding an extra one for thicker sections, these slicers create a double perimeter simultaneously, then a separate single perimeter, leading to disjointed walls.

The ideal transition, as shown in the Prusa Slicer example, generates a fully closed perimeter first, followed by additional perimeters.

Prusa Slicers:

• Use Prusa Slicer for best results
  

Bambu Slicer & Orca:

Enable Advanced settings and then:
• Wall generator: Arachne
• Wall transitioning filter margin: 1000%
• Wall transition length: 150%
• Minimum Wall Width: 150%
• Minimum Feature Size: 50%
• Seam position: Random

Other / Adjust Settings

• To achieve full round perimeters, try:
• Enable "Detect Thin Walls."
• Reduce Extrusion Width for Perimeters & External Perimeters (e.g., 0.45mm to 0.3mm)
• Tilt blocks and enable supports, ensuring the problematic wall is on a slope for a wider profile
• Set Seam Start Position to random
• X-Y contour compensation: +0,34mm
