Polymaker PolyDryer Box

Damp filament is a common cause of failed 3D prints, so the PolyDryer system is designed to dry and store filament in one unit. It dries filament at temperatures up to around 70 °C with 360° airflow to remove moisture evenly. Built-in controls and a timer simplify setup, while a central holder keeps the spool rotating during drying. The sealed design helps prevent moisture and dust from reaching the filament during storage. It works with a wide range of materials, including PLA, PETG, ABS and TPU, and offers multiple power levels to suit different filaments. In a modular setup, you can add PolyDryer Boxes to extend storage and drying capacity, making it possible to keep filament dry and ready for your next project.
