How to Fix Infill Showing Through Walls

Step-by-step fix for infill showing through walls on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix infill showing through walls?

1
Increase wall count to at least 3. More walls create a thicker shell that masks the infill pattern underneath.
Setting: strength.walls.wallLoops
2
Increase top shell layers to 5–7. Pillowing (infill showing on top surface) is solved by adding more solid top layers that bridge over the infill.
Setting: strength.topBottom.topLayers
3
Set wall order to "outer/inner". Printing the outer wall first gives it a cleaner surface since it's not pushed around by previously-printed inner walls.
Setting: quality.advanced.orderOfWalls

Pro tip: Select "Good Cosmetics" above — it sets outer-first walls and ironing to completely hide infill patterns on the surface.
