Important Compatibility Information
The PolyDryer Storage Box XL is a passive storage solution and does not actively heat or dry filament on its own. It uses its sealed design and desiccant to help maintain a low-humidity environment.
For active drying, it can be integrated with the PolyDryer Dry Dock using the optional XL Dock Adapter, which is sold separately. The adapter is not included with the storage box.
The PolyDryer Box XL is compatible with 1.75 mm, 2.85 mm and 3.00 mm filament, making it suitable for a wide range of 3D printing applications.
