SUNLU Filament Dryer E2 The SUNLU FilaDryer E2 is a robust, professional-grade filament dryer and annealer designed for advanced engineering materials. It heats up quickly—reaching up to 110 °C thanks to its 500 W PTC system—enabling both rapid moisture removal and precision annealing for high-performance filaments like PC, PA, ABS, and carbon-fiber blends. With a sealed, dual‑chamber, insulated interior that can hold two 1 kg spools (or one 3 kg spool), it offers excellent airtightness and thermal stability while keeping the exterior below 60 °C. Safety features include dual temperature protection, over‑temperature alarm, and intelligent cooling. Though its steep price and industrial features might be overkill for casual hobbyists, enthusiasts working with premium engineering-grade filaments will find its combo of drying and annealing functionality invaluable.
