Polymaker PolyDryer™ Box XL

The Polymaker PolyDryer™ Box XL is the perfect option for users looking to reliably store large filament spools in a dry environment and print directly from there. Designed for spools up to 3 kg, it combines a heavy-duty seal with practical features for a smooth workflow.

Thanks to its high-quality airtight sealing, moisture is effectively kept out, even with the larger internal volume. This ensures your filaments remain in optimal condition at all times. Particularly practical: you can print directly from the closed box. The filament is guided out through integrated, sealed ports without compromising the dry environment inside.

To ensure you always have full control, a hygrometer is integrated to display the current humidity level. Additionally, the included colour-changing silica gel (up to 110 g) provides a quick visual check of the moisture status.

The box is specifically designed for large spools up to Ø300 x 118 mm (up to 3 kg), meaning fewer spool changes are necessary - ideal for long print jobs or use in print farms. Handling has also been optimised: an integrated handle, a design reinforced for heavy spools, and an improved locking system make it exceptionally convenient to use.
