Sunlu Filament Dryer E2

The SUNLU FilaDryer E2 is a professional-grade filament dryer and annealing machine built for engineering materials. With a working temperature up to 110°C, it's the only tool you need to prepare high-performance filaments like PA-CF, PC, ABS, and ASA - drying and post-print annealing in one machine.

Key Features

• Up to 110°C - Drying + Annealing in One - The only machine needed for engineering-grade workflows. Anneal printed parts to reduce internal stress and dramatically improve impact resistance and durability.
• 500W Ultra-High Heating Power - Reaches 50°C in 20 minutes, 70°C in 30 minutes from room temperature. 500W PTC ensures fast, efficient drying.
• Excellent Airtightness - One-piece silicone plug over line holes, sealing silicone strip on the cover plate, and magnetic closure system. All-round dual-chamber design (top, middle, bottom) enables temperature above 100°C.
• Extra Large Interior - Fits Ø250mm × 153mm spools. Holds 2×1kg, 2×2kg or 1×3kg spools. Compatible with 1.75mm, 2.85mm and 3.0mm filament diameters.
• Built-in Preset Filament Settings - One-click presets for common engineering materials. Timer range 0–99 hours for overnight drying.
• Triple Safety Protection - Alarm beep if temperature exceeds preset by 10°C. Dual-level temperature control (auto-disconnect on over-temp, auto-restore on cooling). Double-layer heat insulation: internal >100°C, external touch <60°C. Fireproof-grade materials throughout.
• More Durable Build - New motherboard cooling fan, metal ball components, improved temperature resistance. New cover prevents debris from falling into air ducts.
• Compatible With 99% of Materials - Engineering: ABS, ABS-CF, ASA, PC, PC-ABS, PC-PBT, CoPA, PA6-GF, PA6-CF, PA12-CF, PA612-CF, PA12, flame retardant PC. Standard: PLA, PETG, TPU, PVA and more.

What is Annealing?

Annealing heats printed parts at a controlled temperature to relax internal stresses introduced during cooling. This improves impact resistance, toughness, and dimensional stability - critical for functional engineering parts like drone components, brackets, screws, and structural housings.

Annealing Tips

• Determine the right temperature for your material before starting.
• Ensure even, gradual heating - avoid rapid temperature jumps.
• Allow gradual cooling for best dimensional results.
• Test with small models first to understand shrinkage before scaling up.
• Account for slight shrinkage in your design when annealing structural parts.
