At Sovol, we believe that reliable 3D printing starts long before the first layer is printed.
One of the most common causes of print failure—often overlooked—is moisture-affected filament.
To help makers, professionals, and engineers achieve more consistent results across a wide range of materials, we are proud to introduce the Sovol SH03 High-Temperature Dual-Chamber Filament Dryer.
Why Filament Drying Matters
Many popular 3D printing filaments are hygroscopic, meaning they absorb moisture from the air over time. This can lead to:
- Stringing and oozing
- Bubbles and rough surface finish
- Reduced mechanical strength
- Poor layer adhesion, especially with Nylon and PC
- Audible popping sounds during extrusion
While sealed storage and desiccants help slow moisture absorption, they cannot restore already wet filament. Active, temperature-controlled drying is essential.
Designed by Sovol: Drying and Storage in One Solution
The SH03 filament dryer is designed to solve two critical needs in one compact system:
- High-efficiency filament drying
- Long-term moisture-controlled storage
Unlike basic filament dryers, SH03 combines controlled heating, active moisture exhaust, and sealed storage—making it suitable for both everyday printing and extended filament protection.
Dual Independent Chambers for Multi-Material Workflows
The SH03 features two fully independent drying chambers, offering unmatched flexibility:
- Each chamber can be set to a different temperature and time
- Dry different filament types simultaneously
- Supports up to 4 filament spools
- Single-chamber operation for improved energy efficiency
This design is ideal for users working with multiple materials or frequently switching between filaments.
True High-Temperature Drying up to 85°C
Many standard filament dryers are limited to lower temperatures that are insufficient for engineering-grade materials.
The Sovol SH03 supports adjustable temperatures from 45°C to 85°C, making it suitable for:
- PLA / PLA+
- PETG
- TPU
- ABS
- PC
- Nylon and other high-moisture filaments
Powered by dual 200W PTC heating modules, SH03 delivers fast and stable heating while maintaining safe and controlled operation.
PTC Heating Technology with 360° Hot Air Circulation
SH03 uses PTC ceramic heating elements, chosen for their safety, stability, and efficiency:
- Automatic temperature regulation
- No exposed glowing elements
- Reduced risk of overheating
- Energy-efficient performance
Combined with an independent airflow system and 360° hot air circulation, heat is distributed evenly throughout the chamber for more consistent drying results.
Active Moisture Exhaust and Auto Dehumidification Mode
Active Moisture Exhaust
During drying, SH03 actively opens its intake and exhaust vents once the target temperature is reached. This allows moisture-laden air to be expelled instead of condensing inside the chamber.
After drying is complete, the vents automatically close to maintain a sealed, low-humidity storage environment.
AUTO Dehumidification Mode
In AUTO mode:
- Users can set a humidity threshold (20%–40%)
- Drying starts automatically when humidity exceeds the threshold
- After reaching the target humidity, SH03 continues drying for 30 minutes
- The system then switches to energy-saving storage mode
This allows SH03 to protect filament even when not actively printing.
Intelligent Safety System with Four-Layer Protection
Safety is a core design principle at Sovol. The SH03 includes multiple layers of protection:
- Dual temperature sensors for accurate chamber control
- Smart 4-wire fan monitoring with automatic alerts
- Software-based thermal runaway protection
- Hardware-level thermal cutoff and PTC self-protection
These systems ensure safe, stable operation during long and high-temperature drying cycles.
Intuitive Touchscreen Control
The SH03 touchscreen interface is designed for simplicity and precision:
- Preset profiles for 7 filament types
- Adjustable temperature and drying time (2–98 hours)
- One-touch parameter copy between chambers
- Real-time temperature and humidity display
- Clear error notifications for easier maintenance
Whether you are a beginner or an experienced user, SH03 is easy to operate.
Designed for Daily Use
- Low operating noise (~47.6 dB at 1 m)
- Heat-insulated base and anti-scald lid design
- High-temperature-resistant rotating shaft
- PTFE filament outlet for printing directly from the dryer
With SH03, you can dry, store, and print without moving your filament.
A Cost-Effective High-Temperature Filament Dryer from Sovol
By combining 85°C high-temperature capability, dual-chamber design, active dehumidification, and multi-spool support, the SH03 delivers professional-grade filament management at an accessible price point.
The Sovol SH03: Built for Reliable Printing
The Sovol SH03 High-Temperature Dual-Chamber Filament Dryer is designed for makers who value consistency, material performance, and long-term reliability.
Whether you are printing advanced engineering materials or simply want better print quality, SH03 helps ensure your filament is always ready to perform.
