Features:

Modular Dryer and Storage System

The Polymaker PolyDryer Dryer Dock and Storage Box combines active filament drying and airtight storage into one integrated system, eliminating the need to transfer filament between separate devices. Once a spool has been dried, it can remain inside the sealed storage box to protect it from moisture until you're ready to print. This streamlined workflow reduces handling, minimizes moisture exposure, and keeps your filament in optimal condition for consistent printing.

Dry, Store, and Print from One Box

Unlike conventional filament dryers that require removing the spool before printing, the PolyDryer allows you to feed filament directly from the sealed storage box using the included PTFE tube. This means the filament stays protected from ambient humidity throughout long print jobs, making it especially beneficial for moisture-sensitive materials like Nylon, TPU, PVA, and Polycarbonate.

360° Heated Airflow for Uniform Drying

The PolyDryer uses an advanced 360° heated airflow system that circulates warm air evenly around the entire spool. This consistent airflow helps remove absorbed moisture more effectively than localized heating methods, ensuring the filament dries uniformly while reducing the risk of overheating or uneven drying.

Three Preset Drying Levels

To accommodate different filament materials, the PolyDryer features three preset drying power levels. Whether you're drying everyday PLA or engineering-grade materials such as Polycarbonate and Nylon, users can select the appropriate setting to achieve effective drying without the complexity of manually adjusting temperatures.

Supports a Wide Variety of Filament Materials

Designed for versatility, the PolyDryer is compatible with most 1.75 mm 3D printing filaments, including PLA, PLA+, PETG, ABS, ASA, TPU, PVB, Nylon (PA), Polycarbonate (PC), PVA, PolySupport™, PolySupport™ for PA12, and many specialty engineering materials. This makes it an excellent solution for hobbyists and professionals working with multiple filament types.

Accommodates Most Standard 1 kg Spools

The spacious storage chamber supports filament spools weighing up to 1 kg with a maximum spool diameter of 205 mm and spool width of 78 mm. It also accommodates many smaller spool sizes, providing flexibility for users with different filament brands and packaging formats.

Airtight Storage for Long-Term Filament Protection

The PolyDryer Storage Box features a high-performance airtight sealing system that helps prevent moisture and dust from reaching your filament. By maintaining a sealed environment after drying, it reduces the need for repeated drying cycles and helps preserve filament quality for extended periods.

Built-In Hygrometer for Easy Humidity Monitoring

An integrated analog hygrometer allows you to quickly check the humidity level inside the storage box without opening it. This simple monitoring system helps users determine when additional drying or desiccant regeneration may be needed to maintain ideal storage conditions.

Reusable Color-Changing Silica Gel Desiccant

The included desiccant box contains reusable color-changing silica gel that actively absorbs moisture trapped inside the storage chamber. As the silica gel changes color, users receive a clear visual indication that it is time to regenerate or replace the desiccant, making maintenance both simple and cost-effective.

Smooth Spool Roller for Reliable Filament Feeding

Inside the storage box, the spool rests on a low-friction roller system that allows smooth filament movement during printing. This helps reduce feeding resistance, supports consistent extrusion, and minimizes unnecessary strain on the printer's extruder.

Expandable Modular Ecosystem

One of the PolyDryer's biggest advantages is its expandable modular design. A single Dryer Dock can be shared among multiple PolyDryer Storage Boxes, allowing users to dry one spool while securely storing many others. This significantly reduces the cost of expanding a filament management system compared to purchasing multiple standalone dryers.

Compact Design for Efficient Workspace Organization

Despite its generous internal capacity, the PolyDryer maintains a compact footprint of approximately 120 × 235 × 290 mm. Its space-efficient design makes it suitable for desktops, workshops, classrooms, makerspaces, and professional print farms where workspace is limited.

Optimized Drying Profiles for Multiple Filament Types

The PolyDryer includes manufacturer-recommended drying programs for various filament materials. These optimized drying durations help users achieve reliable moisture removal while protecting the physical properties of each filament type, resulting in improved print consistency and material performance.

Universal Power Compatibility

Powered by a universal 100–240V AC input with a 24V DC adapter, the PolyDryer is suitable for use in different regions without requiring specialized power equipment. Its efficient 68W maximum power consumption balances effective drying performance with energy efficiency.

Built-In Safety Protection

The PolyDryer incorporates an internal NTC thermistor and automatic overheating protection to ensure safe operation during extended drying sessions. These safety features help maintain stable performance while protecting both the device and the filament from excessive heat.

Complete Ready-to-Use Package

Everything needed to begin drying and protecting filament is included in the box. The package contains the Dryer Dock, Storage Box, spool roller, PTFE tube, hygrometer, desiccant box, reusable color-changing silica gel, two airlocks, power adapter, and user documentation, allowing users to start improving filament storage and print quality immediately after setup.

Designed to Improve Print Quality and Reduce Waste

By effectively removing moisture before printing and maintaining a dry environment afterward, the PolyDryer helps reduce common moisture-related printing issues such as stringing, bubbling, weak layer adhesion, inconsistent extrusion, poor surface finish, and failed prints. The result is better-looking models, stronger printed parts, reduced filament waste, and greater confidence in every print.
