• ①【SUNLU S4 Pro 3D Printer Filament Dryer】– Compared to the SUNLU S4, Upgraded S4 offers faster heating, intelligent temperature control, improved drying efficiency, and a built-in annealing mode for enhanced material performance.
• ②【Dual-Chamber Independent Control】- The SUNLU S4 Pro features two independently controlled chambers, allowing different temperatures, drying programs, and annealing settings to run simultaneously. Dry PLA in one chamber while conditioning PA in the other for maximum flexibility and efficiency.
• ③【Faster Heating & More Efficient Drying】- Upgraded from the SUNLU S4, the S4 Pro FIlaDryer delivers faster heating（85℃/185℉） and improved airflow circulation to remove moisture more effectively. Restore print quality, reduce stringing, improve layer adhesion, and keep your filaments ready for high-performance 3D printing.
• ④【Built-in Annealing Mode for Stronger Prints】- S4 Pro Filament Dryer features a professional annealing mode designed to improve print strength, dimensional stability, and heat resistance. Ideal for engineering-grade materials including PA, PC, PA6-CF, PA12-CF and other advanced filaments.
• ⑤【Automatic Humidity Control】- Simply set your target humidity level from 30% to 50%. The S4 Pro automatically starts drying when chamber humidity exceeds the preset value and stops once it reaches 25%, ensuring your filaments remain dry, protected, and ready to print at all times.
• ⑥ 【Strong Compatibility】- Compatible with PLA, PETG, TPU, ABS, ASA, PA, PC, Nylon, Carbon Fiber, Glass Fiber, and more. It ideal for both professionals and hobbyists.
• ⑦【Large Capacity FilaDryer】- SUNLU filament dryer S4 Pro holds 4×1KG. External size - 458(L)*218(W)*310(H) mm, internal size - 220(L)*210(W)*211*2(H) mm, net weight - 4.7KG.
