[Smarter Drying, Better Printing] The SUNLU FilaDryer S4 Pro is designed to help makers and professionals keep filaments dry, stable, and ready to print. With dual-zone independent control, automatic humidity management, and built-in annealing mode, it delivers a more efficient and flexible filament drying experience.

[Dual-Zone Control, More Flexibility] The SUNLU FilaDryer S4 Pro runs two different drying settings at the same time. Dry PLA / PETG in one chamber while conditioning PA / PC / PP in the other, or set separate programs for different materials to save time and boost productivity.

[Faster Heating, Faster Results] Reach 85°C / 185°F more quickly with upgraded heating and airflow circulation. This helps remove moisture more effectively, reduce stringing, and improve layer adhesion for smoother print performance.

[Built for Advanced Materials] Add professional annealing support to your 3D printing workflow. The built-in annealing mode helps improve strength, dimensional stability, and heat resistance, making it ideal for PA, PC, PP, and other engineering filaments that the annealing temperature at/within 85°C.

[Smart Humidity Management] Set your target RH range from 30% to 50% and let the dryer do the rest. The system automatically starts when internal humidity reaches the set level and stops at 25% RH, helping keep filaments protected and ready to print.

[One Dryer, Multiple Adaptations] Compatible with PLA, PETG, TPU, ABS, ASA, PA, PC, Nylon, Carbon Fiber, Glass Fiber, and more. A large-capacity design for 4 × 1kg spools makes it a reliable choice for home studios, workshops, and 3D printing farms.
