Filament Drying Temperature & Time Chart
How hot and how long to dry each filament in a dedicated dryer, plus the signs of wet filament and how to store it properly.
| Material | Temperature | Time | Moisture sensitivity | Notes |
|---|---|---|---|---|
| PLA | 45–55 °C | 4–8 h | Low | Easiest to print. Leave the door or lid open on enclosed printers to avoid heat creep. |
| PETG | 60–65 °C | 4–6 h | Medium | Sticks very strongly to smooth PEI — use glue stick as a release layer. Prone to stringing when wet. |
| ABS | 60–80 °C | 4–6 h | Medium | Warps without an enclosure. Print in a ventilated room — it releases fumes. |
| ASA | 60–80 °C | 4–6 h | Medium | Like ABS but UV-resistant — the best choice for parts that live outdoors in the Jordanian sun. |
| TPU (95A) | 50–60 °C | 4–8 h | High | Print slowly. Feed it directly rather than through a multi-material system unless the maker supports it. |
| PA (Nylon) | 70–90 °C | 8–12 h | High | Very tough but absorbs moisture within hours — dry before every print and print from a dry box. |
| PC | 70–90 °C | 6–8 h | Medium | Highest heat resistance of common filaments. Needs a hot, enclosed printer. |
| PLA-CF / PETG-CF / PA-CF | 55–80 °C | 6–8 h | Medium | Carbon fiber wears out brass nozzles quickly — use a hardened steel nozzle. Settings follow the base material. |
| PVA (support) | 45–55 °C | 4–6 h | High | Water-soluble support. Store sealed with desiccant — it goes soft in humid air. |
How to use it
- 1Find your material in the chart and check how moisture-sensitive it is.
- 2Set the dryer to the recommended temperature and never go above the upper limit, or the spool windings can fuse.
- 3Dry for the listed time — very wet spools may need the upper end.
- 4Print straight from the dryer, or store the spool in a sealed bag with desiccant.
The right equipment
A filament dryer holds a steady temperature and lets you print straight from the spool while it dries, and newer Bambu Lab AMS units can dry lighter materials such as PLA and PETG. Browse filament dryers or AMS units.

Why filament absorbs moisture
Most filaments are hygroscopic — they pull water out of the air. When wet filament hits the hot nozzle, the water boils, causing popping, stringing, bubbles and weak layers. Nylon and TPU can go bad in hours; PETG in days; PLA in weeks.
Jordan’s summers are dry, but winter rain and humid rooms are enough to spoil an open spool. Keep spools sealed with desiccant, and dry them before long or important prints.
Frequently asked questions
How do I know if my filament is wet?
Popping or crackling while printing, heavy stringing, rough or bubbly surfaces and weak layer adhesion. PETG, TPU and nylon show these signs quickly.
Can I dry filament in the oven?
You can, but it is not recommended: kitchen ovens are inaccurate at low temperatures and can overshoot and ruin the spool. A dedicated dryer is more precise and safer.
Do I need to dry PLA?
PLA absorbs less moisture than most, but a spool that has been open for weeks can benefit from 4–6 hours at 45–55 °C, especially in the humid winter months.
Why not dry hotter to save time?
Above the material’s softening point the windings stick together or the spool deforms. PLA, for example, starts to soften around 55–60 °C.
At what temperature should I dry PETG?
Dry PETG at 60–65 °C for 4–6 hours in a filament dryer.
At what temperature should I dry TPU?
Dry TPU at 50–60 °C for 4–8 hours, and print it straight from the dryer if you can.
