KINGROON KR-01 Filament Dryer Box — 40W, 48Hr Timer, PLA PETG TPU ABS
🌡️ KINGROON KR-01 Filament Dryer Box – 40W, 48Hr Timer, Humidity Display
The KINGROON KR-01 filament dryer box keeps your filament dry, fresh, and print-ready. Four precise temperature presets, a 0–48 hour adjustable timer, and a real-time humidity display give you complete control over the drying process — no guesswork, no babysitting. Single-knob operation makes it simple for any skill level. Compatible with 1.75mm, 2.85mm, and 3.00mm filaments and most standard spool sizes. Ships from the United States.
Why Dry Your Filament?
Most 3D printing problems — stringing, bubbles, poor layer adhesion, rough surfaces — are caused by moisture-absorbed filament. Plastic filaments are hygroscopic, meaning they absorb moisture from the air over time. Once wet, filament degrades print quality dramatically and can be nearly impossible to print cleanly. A filament dryer removes that moisture and restores the filament to like-new condition before printing. If you’ve ever had a spool sitting open for more than a few days, it almost certainly needs drying.
Compatible Filament Materials
| Filament | Recommended Temp | Notes |
|---|---|---|
| PLA / HS PLA / PLA-CF | 45–50°C | Most moisture-sensitive, dry before every print |
| PETG / HS PETG / PETG-CF | 55–60°C | Absorbs moisture quickly, bubbling is a key sign |
| TPU | 50–55°C | Flexible filament, highly moisture-sensitive |
| ABS / ASA | 60–65°C | High-temp materials, use max setting |
| PP | 55–60°C | Dry thoroughly before printing |
| PC | 60°C | Very moisture-sensitive, always dry before use |
Diameter support: 1.75mm, 2.85mm, and 3.00mm filaments. Max spool: Ø200 × 71mm.
