Sovol SH02 vs SH01: The Evolution of 3D Printing Filament Dryers

A comprehensive comparison of Sovol's filament drying solutions - which model truly delivers superior results?

Essential Insights

The SH02 features a powerful 150W PTC heating system that reaches target temperatures up to 3x faster than the SH01's 48W heater
Enhanced temperature control on the SH02 offers a wider range (40-70°C) compared to the SH01's limited presets (40°C, 45°C, 50°C)
Significant user experience upgrades on the SH02 include touchscreen controls and filament-specific presets not available on the SH01

Filament dryers have become essential tools for 3D printing enthusiasts who want to maintain optimal print quality and prevent issues caused by moisture absorption. Sovol offers two popular filament dryer models – the SH01 and the newer SH02 – each with distinct capabilities and features. This comprehensive comparison will help you understand which model best suits your 3D printing workflow.

Performance Comparison: Heating Power and Efficiency

The most significant difference between these two models is their heating system. The Sovol SH02 features a robust 150W PTC (Positive Temperature Coefficient) surround heating system that distributes heat evenly throughout the chamber. This represents a substantial upgrade from the SH01's 48W heater. The enhanced heating capability allows the SH02 to reach 50°C within approximately 7 minutes and up to 70°C within 25 minutes – considerably faster than the SH01.

This performance difference is crucial for users who need to quickly prepare filament for printing or when dealing with highly hygroscopic materials that require thorough drying. The SH02's faster heating means less waiting time before you can start printing with properly dried filament.

Temperature Range and Control

Temperature control is another area where the SH02 shows significant improvement:

The SH01 offers limited temperature presets at 40°C, 45°C, and 50°C
The SH02 provides adjustable temperature settings from 40°C to 70°C in increments

This expanded temperature range makes the SH02 more versatile for different filament types. For example, while PLA typically requires lower drying temperatures (around 45-50°C), materials like Nylon and Polycarbonate benefit from higher temperatures that only the SH02 can provide.

Timer Settings

The timing capabilities also differ between the two models:

SH01: Timer settings from 6-12 hours in 1-hour increments
SH02: Extended timer range from 2-98 hours with greater flexibility

The SH02's expanded timer options allow for both quick drying sessions and extended drying for particularly wet filament or highly moisture-sensitive materials.

Design Features and User Experience

Control Interface

The user interface represents a significant evolution from the SH01 to the SH02:

SH01: Basic control panel with three buttons that can feel cumbersome to operate
SH02: Advanced 3.9-inch touchscreen interface that allows for easier adjustments and monitoring

Beyond just being more intuitive, the SH02's touchscreen enables one-touch selection of preset programs for specific filament types including PLA, TPU, PETG, ABS, ASA, PVA, PC, PA, and PP. These presets automatically configure recommended heat and timer settings, taking the guesswork out of filament drying.

Moisture Protection and Sealing

Effective sealing is critical for a filament dryer, and the SH02 shows improvements in this area:

The SH02 features triple ring seals for better moisture protection
Two desiccant holders (70mm x 50mm x 10mm) at the bottom for use with color-changing silica gel
Thicker sealing materials compared to the SH01

These enhancements mean the SH02 can better protect filaments from moisture even when not powered on, functioning as both an active dryer and a passive storage solution.

Noise Levels

User reports indicate that the SH02 is generally louder than the SH01 due to its larger fan and more powerful heating element. However, with the lid closed, the noise is reduced significantly. The SH01's fan has been reported to become noisier over time, which may be a consideration for long-term use.

Visual Comparison
