J1 Filament Dryer Box for 3D Printer Filaments, 150W PTC, Up to 70°C | Dry While Printing, Humidity Monitoring, Split

Key features

• 150W PTC Heating up to 70°C – The 150W PTC heating system reaches up to 70°C in minutes, drying even moisture-soaked PLA, PETG, and ABS spools evenly. Consistent heat means fewer stringing, bubbling, or clogging issues during long prints
• Split Design for Flexible Setup – Modular split design lets you use each unit independently or stack them for multi-printer setups, saving bench space while keeping every spool dry. Works with 1.75mm filament and fits most 3D printers
• Dry While Printing – Supports drying and printing simultaneously, so you can feed filament directly from the box while it stays at optimal humidity. No more pausing prints to swap spools or waiting for a separate drying cycle
• Long-Term Moisture Control – With built-in desiccant, internal humidity stays stable within ±5% over 21 days, keeping filament print-ready between sessions. The sealed design locks out ambient moisture, so spools stay dry even in humid basements or garages
• Built-in Humidity Monitoring & Safety – The integrated humidity window lets you check internal conditions without opening the box, while dual hardware protection and real-time monitoring keep operation safe. Simple display interface lets you adjust temperature, time, and filament settings in seconds
