Dry and Reliable Storage for Large Spools

The PolyDryer Box XL is specifically engineered for users working with large filament spools, supporting sizes up to 3 kg. This makes it a practical choice for print farms, long-duration prints, or anyone looking to reduce spool changes during production. By keeping filament sealed in a controlled environment, it helps preserve material quality over time and reduces the risk of print issues due to moisture.

Airtight Design That Protects Filament

At the core of the Box XL is its high-integrity sealing system. A 360° silicone gasket and a secure latching mechanism work together to prevent moisture from entering the container. This ensures a stable, low-humidity environment, which is especially important for hygroscopic materials like nylon and PETG.

Monitor Conditions at a Glance

An integrated hygrometer provides real-time humidity readings, giving you full visibility into the internal environment without needing to open the box. Combined with the included color-changing desiccant, you get both digital and visual indications of humidity levels, making it easy to know when maintenance is needed.

Print Directly from the Box

The built-in filament feeding system allows you to print directly from the sealed box without exposing the filament to ambient air. This ensures consistent conditions throughout the entire printing process and eliminates the need to repeatedly open and re-seal the container.

Designed for Practical Daily Use

The Box XL has been designed with user convenience in mind. An integrated handle makes it easy to transport, while the improved latching system simplifies opening and closing, even with heavier spools. Inside, the setup is optimized for smooth filament movement and efficient handling, helping to streamline your workflow.

Part of a Flexible Ecosystem

While primarily a passive storage solution, the Box XL can be integrated with the PolyDryer system via an optional adapter should active drying be required. This modular approach provides the flexibility to expand your setup as your needs evolve, without having to replace your existing storage solution.
