The SUNLU FilaDryer S4 Filament Dryer revolutionizes 3D printing workflow with its industry-leading 4-spool capacity and intelligent humidity control technology. This professional-grade filament dryer eliminates moisture-related printing issues while enabling seamless print-while-dry functionality through eight strategically placed filament outlets and PTFE tubes. Equipped with a powerful 350W PTC heater and triple-fan circulation system, the S4 achieves optimal drying temperatures up to 70°C with exceptional efficiency—heating 6.9 times faster than previous models while maintaining precise ±3°C temperature balance throughout the chamber.
Designed for serious makers and multi-printer setups, this smart dryer features pre-configured settings for all major filament types and advanced humidity monitoring that automatically activates when moisture levels exceed 50%, dropping to a power-saving 80W during maintenance mode. The large touchscreen interface and comprehensive safety systems make professional filament management accessible to users of all experience levels.
Key Features:
Industry-Leading 4-Spool Capacity: Internal chamber (450×210×211mm) accommodates four 1kg filament spools simultaneously, perfect for multi-color printing, bulk drying, and managing diverse material libraries in professional environments.
Intelligent Humidity Control: Advanced humidity sensor with automatic activation when levels reach 50%, maintaining optimal storage conditions at 25% humidity to prevent secondary moisture absorption and ensure consistent print quality.
High-Efficiency Heating System: 350W PTC heater with triple-fan circulation (2 side fans + 1 heating fan) achieves 70°C maximum temperature with 6.9x faster heating compared to standard dryers while maintaining ±3°C temperature uniformity.
Print-While-Dry Technology: Eight filament outlets (4 top, 2 each side) with included PTFE tubes enable direct feeding to up to 4 printers simultaneously, eliminating workflow interruptions and maintaining continuous productivity.
Smart Preset Controls: Pre-configured temperature and time settings for PLA, ABS, PETG, TPU, PA, and PC based on extensive testing data, plus manual adjustment ranges (35-70°C temperature, 0-99 hours timing) for custom materials.
Professional Safety Features: Triple protection system with PTC thermal cutoff, dual-stage temperature switches, and software monitoring, plus gel-coated rollers to prevent spool deformation during extended drying cycles.
