Polymaker PolyDryer Filament Dryer

The PolyDryer is a modular 2-in-1 drying and storage solution designed to protect filaments from moisture and dust. Its sealed design, combined with a 360° airflow system, dries filaments evenly while keeping them secure between uses. It supports a range of popular 3D printing materials and accommodates spools up to 1 kg with dimensions up to 205 mm in diameter and 78 mm in width, and it works with 1.75, 2.85, and 3.00 mm filament. A central holder keeps the spool spinning smoothly during drying, while an LCD screen and timer simplify setup. The unit can be expanded by adding additional PolyDryer Boxes connected to a dock, enabling a customized drying and storage setup tailored to ongoing projects. Three preset drying settings plus a continuous option let you choose the right level for different filaments, and adjustable power levels provide further control. The system heats up to 70 °C and includes temperature control to prevent overheating, with automatic power-off when necessary for safety.
