Practical drybox for large filament spools up to 3000 g
The Polymaker PolyDryer™ Box XL is a high-quality storage box for 3D printer filaments, specifically designed for large spools up to 3 kg. Thanks to the strong airtight seal, moisture is kept out of the box, ensuring filament remains dry for long periods and guaranteeing optimal print results. Furthermore, you can print directly from the closed box, keeping your filament protected from moisture during the printing process.
This practical filament box is ideal for makers, professionals, and print farms that work with large filament spools and are looking for a reliable solution for the storage and use of moisture-sensitive materials such as PLA, PETG, ABS, ASA, Nylon, and TPU.
Key features
- Suitable for filament spools up to Ø 300 x 118 mm (max. 3 kg)
- Strong airtight seal for long-term dry storage
- Direct printing from the closed box is possible
- Integrated hygrometer for monitoring humidity
- Includes color-changing silica gel (up to 110 grams)
- Reduces moisture absorption and prevents print issues
- Optimized design for heavy filament spools
- Convenient integrated carrying handle
- Improved locking system for easy use
- Supports filament diameters of 1.75 mm, 2.85 mm, and 3.00 mm
Always dry filament for better print quality
Moisture in filament can lead to poor layer adhesion, stringing, air bubbles, and reduced print quality. The Polymaker PolyDryer™ Box XL helps prevent these issues by creating a controlled dry environment in which your filament is stored safely.
Thanks to the integrated hygrometer, you can check the humidity at a glance. Additionally, the included color-changing silica gel visually indicates when it is time to regenerate or replace the desiccant.
Print directly from the storage box
A major advantage of the PolyDryer™ Box XL is that you can use filament directly from the box while printing. Through the sealed filament feed, the filament is guided to the printer without losing the dry environment. As a result, the material remains protected from moisture, even during long print jobs.
Expandable with the PolyDryer™ system
The PolyDryer™ Box XL is part of the modular Polymaker PolyDryer™ system. In combination with the optional PolyDryer Dry Dock (not included), the box can be expanded into an active filament dryer. This allows you not only to store filament dry but also to actively remove moisture for the best possible print performance.
