How to Fix Gaps / Holes in Top Layer

Step-by-step fix for gaps / holes in top layer on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix gaps / holes in top layer?

1
Increase top shell layers to 5–7 (default is often 3–4). More solid top layers bridge over the infill pattern more completely.
Setting: strength.topBottom.topLayers
2
Run flow rate calibration — if flow is even 3–5% too low, top layers won't fill completely.
Setting: Flow ratio
3
Enable ironing (Quality > Ironing > Top surface only). The nozzle makes an extra pass with minimal extrusion, filling micro-gaps.
Setting: quality.ironing.type

Pro tip: Select "Good Cosmetics" above — it enables ironing and outer-first wall order for perfectly smooth top surfaces.
