# Walls
|
|
|
|
In 3D printing, "walls" refer to the outer layers of a printed object that provide its shape and structural integrity.
|
|
Adjusting wall settings can significantly affect layer adhesion, strength, appearance and print time of your model.
|
|
|
|
|
|
|
|
- [Wall loops](#wall-loops)
|
|
- [Alternate extra wall](#alternate-extra-wall)
|
|
- [Detect thin wall](#detect-thin-wall)
|
|
|
|
## Wall loops
|
|
|
|
"Wall loops" refers to the number of times the outer wall is printed in a loop.
|
|
Increasing the wall loops will:
|
|
- Enhance:
|
|
- Layer adhesion
|
|
- Strength
|
|
- Rigidity
|
|
- Reduce infill ghosting
|
|
- Increase print time
|
|
|
|
## Alternate extra wall
|
|
|
|
This setting adds an extra wall to every other layer. This way the infill gets wedged vertically between the walls, resulting in stronger prints.
|
|
When this option is enabled, the ensure vertical shell thickness option needs to be disabled.
|
|
|
|
> [!WARNING]
|
|
> It's not recommended to use this option with:
|
|
> - [Lightning infill](strength_settings_patterns#lightning) as there is limited infill to anchor the extra perimeters to.
|
|
> - **[Ensure vertical shell thickness: ALL](strength_settings_advanced#ensure-vertical-shell-thickness)**
|
|
|
|
## Detect thin wall
|
|
|
|
By default, walls are printed as closed loops. When a wall is too thin to contain two line widths, enabling "Detect thin walls" prints it as a single extrusion line.
|
|
Thin walls printed this way may have reduced surface quality and strength because they are not closed loops.
|
|
|
|
> [!TIP]
|
|
> Usually, it is recommended to use [Arachne wall generator](quality_settings_wall_generator#arachne) which will disable "Detect thin walls" because it uses a different approach to wall generation.
|
|
|
|
- In small details it can generate details that wouldn't be possible with traditional wall generation methods.
|
|
|
|
|
|
- In large prints, it can generate defects more easily due to the reduced wall thickness.
