Polymaker PolyDryer Filament Dryer (Dryer Dock + Storage Box)

The Polymaker PolyDryer is a modular filament drying and storage system that pairs a heated Dry Dock with a sealed PolyDryer Box. Dry a damp spool on the dock, lift the box off, and keep the filament sealed and ready to print. Co-developed with FabNotion, it is built for makers who want dry filament without juggling separate dryers and storage bins.

Dry and Store in One System

One Dry Dock works with as many PolyDryer Boxes as you like. Keep each material in its own box, then set whichever spool needs attention on the dock. A 360° airflow design moves warm air evenly around the spool, and three preset power levels cover common materials such as PLA, PETG, ABS, TPU, PC, and nylon. The highest setting reaches roughly 68–73 °C inside the box, depending on room conditions, spool size, and material.

Sealed Storage You Can Print From

The PolyDryer Box uses a tight latching lid and airlock fittings, so filament can feed straight to your printer through the included PTFE tube without opening the box. A built-in hygrometer shows the humidity inside at a glance, and color-changing silica gel desiccant turns from orange to dark green as it absorbs moisture. When it is saturated, the desiccant can be regenerated on the Dry Dock, in an oven, or in a microwave.
