SUNLU FilaDryer E2 Professional Filament Drying and Annealing

Born for engineering filaments — fast drying, precise annealing, bigger capacity.

The SUNLU FilaDryer E2 combines high-power drying with true annealing up to 110 °C to unlock the full performance of engineering materials. A sealed, dual-chamber design improves thermal insulation and moisture control, while smart safety protections keep operation reliable for home or pro use.

Key Features:

• Up to 110 °C annealing: Optimize ABS, ASA, PC, PC-ABS, PA/nylon, and carbon/glass-filled variants.
• 500 W PTC heater: Rapid heat-up — ~20 min to 50 °C and ~30 min to 70 °C (room temp baseline).
• Dual-chamber + sealed design: Silicone-sealed cable passthrough and lid gaskets reduce moisture ingress.
• Large capacity: Fits up to Φ250 mm × 153 mm spools; tested to hold 1 kg × 2, 2 kg × 2 or 3 kg × 1 (SUNLU spool sizes).
• Preset materials & one-click apply: Quick setup for common filaments.
• Multi-diameter support: Compatible with 1.75 mm, 2.85 mm, and 3.0 mm filaments (PTFE tubes included).
• Smart safety: Dual over-temp control with auto cut-off & recovery; double-layer insulation keeps exterior < 60 °C when interior > 100 °C.

• Standby Power: ≤ 1 W

Benefits:

• Removes absorbed moisture to reduce bubbles, stringing and poor layer adhesion
• Anneals engineering filaments for improved impact resistance and toughness
• Restores performance of opened or long-stored spools

Ideal For:

• ABS / ABS-CF, ASA, PC, flame-retardant PC, PC-ABS, PC-PBT
• CoPA / PA6-GF / PA6-CF / PA12-CF / PA612-CF / PA12 and more

Notes & Safety: Follow filament maker guidance for drying/annealing temps and durations. Ensure your spool’s heat resistance matches the set temp (e.g., ≥ 70 °C when drying at 70 °C). Avoid touching the unit while hot; exterior may be ≥ 55 °C at higher setpoints. Keep the lid closed during operation for best results.
