Orca Slicer Top Interface Layers: Enhancing Surface Finish

Top interface layers play a critical role in the final look of your model’s upper surfaces. Orca Slicer allows you to define:

• Top layer count
• Ironing patterns
• Top skin overlap
• Speed modifiers for surface smoothing

Orca Slicer’s Top Interface Layers

Setting	Description	Practical Tip
Top Layer Count	Defines the number of topmost layers printed. More layers provide a smoother surface.	Increase the top layer count to cover imperfections from lower layers, ensuring a polished and uniform finish.
Ironing Patterns	The nozzle moves across the top layers to smooth the surface, reducing layer lines.	Enable ironing for a glossy or smoother surface, especially for prints where aesthetics are important (e.g., PLA).
Top Skin Overlap	Determines how much the outermost layers overlap with the interior infill. A higher overlap improves adhesion.	Increase overlap to reduce gaps and ensure better bonding between top layers and infill, leading to a more seamless surface.
Speed Modifiers	Adjusts the printing speed for top layers to improve surface smoothing.	Reduce the print speed for top layers to achieve finer, smoother finishes on the model’s upper surface.
Material Selection	Different materials affect surface finish quality.	Use PLA or PETG for easier smooth finishes. For tougher materials like ABS or Nylon, fine-tune other settings.
Temperature Settings	Higher temperatures can improve layer adhesion but may increase stringing or oozing.	Adjust temperature settings according to the filament used to maintain good layer adhesion while avoiding surface defects like stringing.

By adjusting the top interface layers, users can improve surface quality and minimize visual imperfections like layer lines or under-extruded patches.
