Skin infill density
With the “Locked Zag” pattern: how much plastic goes into the skin, the band of infill right against the walls. Raising it reinforces the part exactly where it needs it most.
How it works
Much of a part's strength is in the walls and in what's right behind them. With “Locked Zag” you can make the skin denser than the skeleton and gain stiffness without filling the whole inside.
By default it takes the same density as the general infill.
When to change it
- A box with screws in the corners or a bracket that carries weight near its edges: 30–50% in the skin and 10–15% in the skeleton.
- A tool handle that has to feel firm when you squeeze it, without using as much plastic: 40% in the skin.
- The usual: same as the infill.

Watch out for
- It only shows up with the “Locked Zag” infill pattern.

What Bambu Studio says
The portion of the model's outer surface within a certain depth range is called the skin. This parameter is used to adjust the density of this section.When two regions have the same sparse infill settings but different skin densities, This area will not be split into two separate regions.default is as same as infill density.
