• 【150W PTC Heater up to 70°C】 – The 150W PTC heating system reaches up to 70°C within a few minutes and dries even moisture-affected PLA, PETG, and ABS spools evenly. Even heat means less stringing, bubbling, or clogging during long printing sessions.
  
• 【Split Design for Flexible Setup】 – The modular split design allows each unit to be used independently or stacked for multi-printer setups, saving bench space and keeping each spool dry. Works with 1.75 mm filament and fits most 3D printers.
  
• 【Drying While Printing】 – Supports simultaneous drying and printing, allowing you to feed filament directly from the box while it stays at optimal humidity. No more pausing prints to change spools or waiting for a separate drying cycle.
  
• 【Long-term Moisture Control】 – With built-in desiccant, the internal humidity remains stable within ±5% for 21 days, keeping filament ready between print sessions. The sealed design keeps external moisture out, so spools stay dry even in damp basements or garages.
  
• 【Integrated Moisture Monitoring & Safety】 – The integrated moisture window allows checking internal conditions without opening the box, while double hardware protection mechanisms and real-time monitoring ensure safe operation. The simple display interface allows adjusting temperature, time, and filament settings in seconds.
