How to Fix Wet / Damp Filament (Popping, Bubbles)

Step-by-step fix for wet / damp filament (popping, bubbles) on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix wet / damp filament (popping, bubbles)?

1
Dry the filament immediately: PLA at 45–55°C for 4–6hrs, PETG at 65°C for 6–8hrs, Nylon/PC at 80°C for 8–12hrs.
2
Store filament in sealed bags with desiccant after drying. Nylon and PVA absorb moisture in hours; PETG in days.
3
If you must print without drying: increase nozzle temperature by 5–10°C and reduce print speed by 20%.
Setting: others.nozzle.nozzleTemp

Pro tip: Wet filament ruins surface quality. Select "Good Cosmetics" above to see material-specific temperature and speed settings — but always dry filament first.
