The Polymaker PolyDryer™ Box is a hermetically sealable storage box that complements the PolyDryer™ filament dryer and protects filament from moisture even after drying. It maintains optimal conditions for spool storage and extends their lifespan without compromising print properties.

Key features

The PolyDryer™ Box is designed as a modular accessory for the Polymaker PolyDryer™ system. Thanks to its rubber seal and integrated filament feed opening, it allows printing directly from the box, eliminating material contact with airborne humidity. Silica gel packets can be placed inside to maintain low relative humidity. The box is compatible with standard spools from common manufacturers and its construction withstands regular operational wear. It is suitable for sensitive materials such as Nylon, PETG, Polycarbonate, ASA or TPU.

Technical parameters

Who is the Polymaker PolyDryer™ Box suitable for

The box will be appreciated by users who work with hygroscopic materials and need to keep them dry between individual prints. It is ideal for workshops, offices and home users who want to ensure consistent print quality, minimize filament breakage and avoid problems caused by moisture absorption (bubbles, stringing, brittle prints). It also finds use in professional environments where consistent storage conditions for technical filaments must be maintained.

Tips for use

• Before inserting the spool, dry the filament first in the PolyDryer™ dryer to achieve optimal dryness.
• Always place silica gel packets or a humidity indicator inside the box to monitor conditions.
• Keep the filament feed opening clean to prevent material jamming.
• Store the box away from direct sunlight and heat sources.
• Regularly check the condition of the seal and replace saturated silica gel.
• Boxes can be stacked to save space in the workshop.
