Quick diagnosis
Identify wet filament by popping, stringing, rough surfaces, brittle filament, and inconsistent extrusion.
Likely causes
- Moisture absorbed from air
- Old spool left open
- Poor storage container
- High humidity print room
Step-by-step fix
- Listen for popping or hissing at the nozzle.
- Compare with a known dry spool.
- Dry the spool using the correct temperature for the material.
- Store filament with desiccant after drying.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
