Filament Drying Box eSun EBOX-LITE for 1.75mm Filament Capacity

eSun EBOX-LITE is a compact filament drying box designed for 1.75 mm filament spools. It creates a controlled low-humidity environment to reduce moisture absorption and maintain filament printability. The unit supports common 1.75 mm materials and is intended for storage and pre-print drying to minimise defects related to damp filament, such as bubbling, increased stringing and layer adhesion problems.

Advantages

The EBOX-LITE provides a stable drying environment with simple operation and compact dimensions suitable for desktop use. By lowering filament moisture content it helps improve print consistency and reduces the frequency of filament-related print failures. The box allows users to store multiple spool types in a dry atmosphere to prolong filament shelf life and ensure more predictable extrusion behaviour during printing.

Suitable for

• Drying and storing 1.75 mm PLA, ABS, PETG and other common 1.75 mm filaments
• Preparing filament spools before 3D printing to reduce bubbles and stringing
• Maintaining filament condition in humid environments or workshops
• Small-scale printing setups and desktop 3D printer users

Key specifications

• Filament diameter compatibility: 1.75 mm
• Designed capacity: fits standard-sized filament spools (1.75 mm)
• Function: controlled drying and storage to reduce moisture uptake
• Form factor: compact, desktop-oriented enclosure for easy placement

How to use

Place one or more 1.75 mm filament spools inside the EBOX-LITE and close the lid to create a sealed environment. Set the recommended drying time and temperature according to the filament manufacturer's guidance or common practice for the filament type. Allow the unit to run until the filament reaches an appropriate dryness level before loading it into the printer. For storage, keep the spools inside the box with the drying cycle or desiccant active as needed to maintain low humidity.

Usage recommendations

Follow filament manufacturer drying guidelines for temperature and duration when available. Use the EBOX-LITE for a pre-dry cycle before printing hygroscopic materials such as PETG or ABS, and keep filament spools sealed inside the box between prints in humid environments to preserve print quality.
