How to Fix Rough / Droopy Overhangs

Step-by-step fix for rough / droopy overhangs on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix rough / droopy overhangs?

1
Reduce overhang threshold angle to 35–40° and enable tree supports. Tree supports leave smaller contact marks and are easier to remove cleanly.
Setting: support.thresholdAngle
2
Slow down outer wall speed to 80–100 mm/s on overhangs. Faster printing doesn't give the filament enough time to cool before the next layer.
Setting: speed.layers.outerWall
3
Increase part cooling fan to 100% for PLA/PETG overhangs. Better cooling = the filament solidifies faster and droops less.
Setting: Cooling fan

Pro tip: Select "Good Cosmetics" above — it enables tree supports with rectilinear interface pattern for the smoothest possible overhang surfaces.
