About filament dryers
Most filaments absorb moisture from the air. Wet filament pops and strings as it prints, and nylon, TPU and PETG are affected far more than PLA. A dryer bakes the water back out at a controlled temperature and many can feed the printer while they run.
The maximum temperature decides which materials a dryer can handle: around 50°C covers PLA and TPU, 65°C covers PETG, and nylon, ABS, ASA and PC want 70-80°C. Spool capacity matters if you print from several spools at once.
Prices are checked against our own price history, so a deal only counts when the price is genuinely lower than usual, not just lower than a list price.
Common questions
What temperature should I dry filament at?
Roughly 45-50°C for PLA, 55°C for TPU, 65°C for PETG and 70-80°C for ABS, ASA, nylon and PC, usually for four to six hours. Always stay below the filament's glass transition temperature.
Do I need a filament dryer for PLA?
Not usually. PLA absorbs moisture slowly, so a sealed box with desiccant is enough for most people. A dryer earns its place with PETG, TPU, nylon and other hygroscopic materials.
