How to Fix Visible Z-Seam

Step-by-step fix for visible z-seam on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix visible z-seam?

1
Set seam position to "Back" or "Nearest" in Quality > Seam. "Back" hides the seam on the least visible face; "Nearest" distributes it.
Setting: quality.seam.position
2
Enable "Wipe before external perimeter" or use Scarf joint seam (if available). These blend the layer transition to make the seam nearly invisible.
3
Set wall order to "outer/inner" in Quality > Advanced. Printing outer walls first gives the seam a cleaner transition point.
Setting: quality.advanced.orderOfWalls

Pro tip: Select "Good Cosmetics" above — it automatically sets seam to back, enables outer-first walls, and adds ironing for the cleanest possible surfaces.
