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 for printed parts made out of engineering materials with an annealing temperature of 85°C or less. [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 (Nylon), PC, and variants with carbon fiber or glass fiber fill, and more. A large-capacity design for 4 × 1kg spools makes it a reliable choice for home studios, workshops, and 3D printing farms.
