Sovol SH01 Spool Holder Filaments Dryer Box — Dry, Protect, and Perfect Your 3D Printing Filaments

Designed for 1.75 mm and 2.85 mm filaments, the Sovol SH01 is more than a spool holder—it’s a dedicated dehydrator that keeps PLA, PETG, ABS, and TPU filament consistently dry for better print quality on FDM 3D printers.

Why drying matters

• Filaments are hygroscopic—moisture leads to print failures, brittle material, poor layer adhesion, and rough surface finish.
• The SH01 actively removes excess moisture, yielding smoother surface textures and stronger, more reliable layer bonding.

Real-time monitoring and precise control

• Inline display shows current temperature and humidity inside the dry box for ongoing visibility.
• Set heating to 40°C, 45°C, or 50°C with selectable drying times from 6 to 12 hours to match your material and environment.
• If the ambient room temperature is below 16°C, the internal temperature may not hit 50°C—but drying efficiency remains effective.

Power-off drying mode with long-term storage

• Silicone and PTFE seal design allows safe storage of filaments for extended periods without power.
• Option to place up to four desiccant bags inside (not included) to further improve drying efficiency and moisture control.

Large, practical capacity

• Accommodates 2 filament rolls with a width under 70 mm, or 1 roll with a width under 150 mm.
• For optimal moisture evaporation, open the PTFE seals on top during heating.

Even heating for consistent drying

• Built-in fan uses thermodynamic air principles to distribute heat evenly around the filament, speeding up drying and improving consistency.

Usage tips and support

• Load filament through the outlet with the direction set counterclockwise so the bottom pulley feeds smoothly.
• If the display shows E0 or E1 errors, open the box to inspect all cable sockets on the motherboard; contact support for replacements if needed.
