PolyDryer Box XL (box only)

PolyDryer Box XL: airtight storage for large-format technical filaments

The PolyDryer Box XL is a storage solution designed to protect moisture-sensitive filaments, especially during long or demanding prints. Designed for professional environments, it ensures high sealing performance validated through rigorous testing (water, smoke, humidity), effectively limiting material degradation.

Its compatibility with large spools up to 3 kg makes it an ideal choice for continuous production. Integrated into the PolyDryer ecosystem, it can evolve into an active drying solution. Reliable, easy to handle, and built from real user feedback, it meets the practical constraints of 3D printing workshops.

Key advantages of the PolyDryer Box XL

Advanced sealing performance

The PolyDryer Box XL provides effective protection against moisture thanks to an optimized sealing system.

Tested under real conditions (water ingress, smoke leakage, humidity rise), it helps preserve the mechanical and extrusion properties of technical filaments, especially hygroscopic materials such as nylon or TPU.

Large spool compatibility

Designed to accommodate spools up to 300 mm in diameter and 118 mm in width, the Box XL is ideal for industrial filament formats (up to 3 kg).

It reduces handling and helps optimize production continuity on professional machines.

Print directly from the box

Thanks to its integrated feeding system with sealed filament paths, you can print directly from the box without compromising the internal environment.

This ensures consistent humidity stability throughout the entire print, even during long production cycles.

Technical features and innovations

Integrated humidity monitoring

The PolyDryer Box XL includes a hygrometer for real-time monitoring of internal humidity levels. Combined with 110 g of silica gel with saturation indicator, this system provides both visual and measured control. It allows users to anticipate desiccant regeneration needs and maintain optimal storage conditions over time.

Expandable PolyDryer ecosystem

The PolyDryer Box XL goes beyond passive storage. It can be connected to the PolyDryer Dry Dock via an adapter (optional or 3D printable), transforming it into an active drying system.

This modular approach allows users to adapt their setup depending on materials and production requirements.

Workshop-oriented ergonomics

Developed based on user feedback, the PolyDryer Box XL features an integrated handle for easier transport of heavy spools. Its redesigned locking system simplifies opening and closing, even in production environments. Loading is also optimized to handle large spools efficiently.

Multi-material compatibility

Compatible with 1.75 mm and 2.85 / 3 mm filaments, the PolyDryer Box XL supports a wide range of technical materials. It is particularly suited for moisture-sensitive polymers while remaining versatile for standard applications, making it a valuable addition to any professional setup.
