Polymaker PolyDryer Box (PX01003) - Filament Dryer and Storage Box

The Polymaker PolyDryer Box (PX01003) is a passive filament dryer and storage box designed to keep your 3D printing filaments dry and ready for use. With an airtight seal and integrated digital hygrometer, it provides a controlled environment for up to two 1kg spools or one 2kg spool, ensuring optimal print quality by preventing moisture absorption.

Advantages

Maintains filament dryness for consistent printing results. The integrated hygrometer allows real-time humidity monitoring, while the passive desiccant system uses included silica gel bags to absorb moisture without electricity. Six filament output ports enable direct printing from the box, and the integrated bearings ensure smooth filament feeding.

Suitable for

• 3D printer users who need to store and dry PLA, ABS, PETG, TPU, and other hygroscopic filaments
• Workshops and labs requiring a reliable, low-maintenance filament storage solution
• Users with multiple spools who want to keep filaments ready for immediate use
