PolyDryer™ Box XL: Sealed Storage for Large Filament Spools

Superior Sealing Performance
PolyDryer™ Box XL features a high-integrity sealing design verified through water leakage, smoke leakage, and long-duration humidity testing. It delivers sealing performance comparable to the standard PolyDryer Box with no degradation despite its larger internal volume.

Print Without Breaking the Seal
The integrated filament feeding system lets you print directly from the sealed box. Filament routes through sealed airlocks, maintaining the sealed environment during the entire print. No more opening your storage every time you start a job.

Always Know Your Filament's Humidity
A built-in hygrometer provides real-time humidity readings, and the included color-changing silica gel desiccant (up to 110g) gives you an instant visual check on moisture levels inside the box.

Built for 3kg Spools
Designed for spools up to 3kg (Ø300 × 118mm), Box XL reduces spool changes and keeps printing workflows smooth — ideal for print farms and heavy users running large-format or long-duration jobs.

User-Centered Design
Easier to carry with an integrated handle, easier to load with a design built for heavy spools, and easier to open with a new latch system. Box XL is built around real user feedback.

Part of the PolyDryer™ Ecosystem
Box XL integrates with the PolyDryer Dry Dock via an optional Dock Adapter (sold separately) for active drying capability. Compatible with 1.75mm, 2.85mm, and 3.00mm filament diameters.

Curious

Is the spool mount just a plastic cylinder or does it spin on bearings?

Polymaker

The standard box comes with both options for a center cylinder or bearings to roll on, but the larger box only has the center spool holder option.
