Good prints start
with dry filament.
Popping, stringing or a spool that's been sitting out? Find your maker's drying settings, then give that filament somewhere dry to live.
Where are you starting?
Something's not printing right.
Know which signs point to moisture, and which could have another cause.
02 / DRYGet the settings for your spool.
Compare maker-sourced temperatures and times without mixing drying methods.
03 / STOREKeep the moisture out.
A sealed box, suitable desiccant and a humidity reading each have a job to do.
How hot?
How long?
Start with the maker of your filament. These examples show why a single setting for each material isn't enough.

|---|---|---|
| PLA Prusa · Prusament PLA / rPLA | 45 °C | 6 h |
| PETG Prusa · Prusament PETG (all versions) | 55 °C | 6 h |
| TPU Prusa · Prusament TPU | 60 °C | 4–6 h |

Different spools. Different needs.
Sources you can check.
Claims you can trust.
We don't test products. Every temperature and time comes from the filament or dryer maker, linked and dated. “Lab” is our name, not a claim of testing.
We explain the limits alongside the settings, so you can make sense of the advice for your own spool.
How we put these guides together →Do I need a dryer or a dry box?
A dryer removes moisture under the maker's specified conditions. A dry box limits moisture exposure during storage. A sealed box alone doesn't establish that a wet spool is ready to print. Choose a storage approach.
Can humidity tell me whether my filament is wet?
A hygrometer measures the air around it, not the moisture inside your filament. Use it to monitor storage, and use your maker's drying guidance for the spool. Check humidity and dew point.
