Filament Diagnostic Tool

Is My Filament Wet?

Wet filament is one of the most common causes of bad prints, and it is easy to miss. Pick your material, check off what you are seeing, and get a quick verdict plus a sensible drying starting point.

Step 1. Your material
Step 2. What are you seeing?

Check every symptom that applies. The more you check, the stronger the signal that moisture is the culprit.

Starting points by material

Highlighted for your selected material once you run the check. These are general starting points, not exact settings: always verify against your dryer and the material spec sheet.

Material Temp Time
PLA 45-55 C 4-6 h
PETG 60-65 C 4-6 h
TPU 50-55 C 4-6 h
ABS/ASA 60-70 C 4-6 h
Nylon (PA) 70-80 C 8-12 h
PC 70-80 C 6-8 h

PETG, TPU, Nylon, and PC absorb moisture fastest. PLA absorbs more slowly but still does in humid conditions, so do not assume it is safe just because it printed fine last month.

This tool offers general guidance based on common, well-established drying ranges. It is not a substitute for your filament manufacturer's published specifications. When in doubt, follow the spec sheet and run a small test print.
