Filament drying temperature and time chart
Find manufacturer drying temperatures and times for PLA, PETG, TPU, ASA, PC Blend, and PA11-CF, then compare seven official dryer records from SUNLU, Polymaker, Creality, EIBOS, Sovol, and PrintDry.
Drying settings vary by material, brand, and formulation. Check the instructions for your exact spool.
Dry filament at the temperature and for the time specified by its manufacturer. Prusa’s current chart for the six Prusament materials covered here runs from 45 °C for PLA/rPLA to 90 °C for PA11-CF. The dryer comparison adds official records for the SUNLU FilaDryer S2 and S4 Pro, Polymaker PolyDryer, Creality SpacePi X4, EIBOS Polyphemus, Sovol SH03, and PrintDry PRO4, while preserving each manufacturer’s caveats.
Filament drying chart
The material settings remain specific to the named Prusament products. The dryer table farther down compares seven current machines without turning their maximum temperature into a promise of even heat around a spool.
| Filament type | Drying temperature | Drying time | Applies to |
|---|---|---|---|
| Prusament PLA / rPLA | 45 °C | 6 hr | Prusament-specific guidance |
| Prusament PETG | 55 °C | 6 hr | Prusament-specific guidance |
| Prusament TPU 95A | 60 °C | 4–6 hr | Prusament-specific guidance |
| Prusament ASA | 80 °C | 4 hr | Prusament-specific guidance |

Wet filament symptoms
Choose the symptoms you see. The same problems can come from slicer settings, the nozzle, or the feed path, so compare the same print before and after drying.
No signs selected
Keep the file, profile, printer, orientation, and filament the same. Dry the spool using the manufacturer’s cycle, then compare the result. If nothing improves, check the nozzle, profile, feed path, and printer.
Seven official product records
Will your filament dryer get hot enough? Compare the SUNLU FilaDryer S2 and S4 Pro, Polymaker PolyDryer, Creality SpacePi X4, EIBOS Polyphemus, Sovol SH03, and PrintDry PRO4, then test a documented ceiling against the exact Prusament cycles above.
A maximum setting answers only one question. Airflow, sensor position, spool size, room conditions, and temperature uniformity still change the result.

Creality notes that the two chambers can differ by 1–5 °C while heating.

Timer: 30 minutes–24 hours or unlimited
This record is pinned to the U.S. 110 V, 80 °C option. Confirm the label on the unit because EIBOS also exposes a 70 °C version.

Polymaker says one temperature cannot represent the whole box, so this guide will not convert the published 68–73 °C range into a fixed comparison ceiling.

PrintDry states that the area near the hot-air outlet is hotter than areas farther away.

Sovol’s formal specification lists 400 W and an 85 °C ceiling. A conflicting 150 W body caption is excluded from this record.

Use 70 °C only as the published ceiling, not proof of an even spool temperature.

Timer: Independent temperature and time control by zone
SUNLU publishes an 85 °C selectable maximum for the S4 Pro; even so, the setting is not an independent uniformity test.

No drying cycle can be compared until the material is known.

SUNLU lists the FilaDryer S2 at a maximum of 70 °C. That reaches the lower-temperature references on this page, but not the 80–90 °C Prusament cycles shown for ASA, PC Blend, and PA11-CF.

After drying
Prusa recommends closed storage with desiccant, especially for materials that absorb moisture quickly. A dry box helps keep a dry spool dry, but it does not replace the manufacturer’s active drying cycle for a wet spool.
Follow the filament maker’s temperature and time.
Print the same file again and compare the result.
Seal the spool with maintained desiccant.
