Only one wall on first layer
In Bambu Studio, the profile 0.20mm Standard @BBL A1 sets it toNo
The first layer gets a single wall and the rest is solid infill. It's for bases with fine details, where a second wall would eat into the design.
How it works
On the first layer, walls are printed with wide lines (0.5 mm). If the base has letters, holes or thin shapes, two wall loops take up a millimeter and the detail disappears. With a single wall, the bottom surface pattern reaches further and the detail is kept.
It only affects the first layer; all the others keep their normal walls.
When to change it
- A sign or a stamp with text on the face that touches the plate: turn it on.
- A normal part, like a bracket or a box: leave it off; two walls give a firmer edge.
Typical values
| Value | What for |
|---|---|
| Off | Defaultdefault |
| On | One wall on the first layer |
Watch out for
- With a single wall, the outline of the first layer is a bit weaker: on tall, narrow parts it may not stick to the plate as well.
