Product Description

Sovol SH03 Filament Dryer is a high-performance, dual-chamber dryer and storage box for 3D printing filaments. Thanks to two independent heating zones and PTC heating up to 85 °C, it reliably dries even demanding technical materials such as PA, PC, ASA or PETG, while being gentle on common filaments like PLA or TPU.

The device holds up to four 1kg spools (or two wider spools up to 150 mm wide) and combines active drying with long-term storage. The automatic dehumidification function monitors internal humidity and, if necessary, cyclically starts drying so that the filament remains constantly in optimal condition for printing.

Main Advantages

• Double heating chamber – two independently adjustable zones allow drying different materials simultaneously at different temperatures.
• High temperature up to 85 °C – suitable for standard and technical filaments (PLA, ABS, PETG, TPU, PA, ASA, PC, PP, PET and others).
• Capacity up to 4 spools – holds four standard 1kg spools (≤ 70 mm wide) or two wider spools up to 150 mm.
• Active dehumidification – automatic circulation and exchange of humid air maintains a stably low relative humidity inside the box.
• Precise time and temperature control – temperature setting in the range of 45–85 °C, timer up to 98 hours in 2-hour increments, display of temperature and humidity.
• Compatibility with 1.75 mm and 2.85 mm filament – thanks to the included PTFE lead-throughs and the possibility of printing without them.
• Quiet operation (< 50 dB) – suitable for home workshops and offices, does not disturb during work.
• Safe operation – PTC heating with overheat protection and a cover with anti-slip/anti-scald treatment.

Usage and Printing Benefits

Moist filament causes popping, bubbles, matte surface, stringing and weak layers. The Sovol SH03 dryer minimizes these problems by:

• removing moisture from filaments before printing,
• keeping spools dry long-term during storage,
• enabling printing from demanding hygroscopic materials (e.g. nylon, PC, ASA) with significantly higher reliability.

The dryer is suitable for individual FDM printers as well as a central drying box for multiple printers or AMS/Multimaterial systems.

• Temperature and humidity display (0–99 % / 0–99 °C)
• Automatic mode – cyclic drying according to humidity
• Capacity 4× 1kg spool (≤ 70 mm) or 2× 1kg/2kg spool (≤ 150 mm)
• Support for 1.75 mm and 2.85 mm diameters
• Possibility of inserting silica gel for even better drying and storage
• Quiet operation < 50 dB
• Improved seal with PTFE bushings
• Safety overheat protection

Technical Parameters

Compatibility

Sovol SH03 is universal and works with the vast majority of FDM printers on the market (Prusa, Bambu Lab, Creality, Anycubic, Elegoo, Sovol and others). Thanks to multiple filament outlets, the dryer can easily be placed next to or above the printer and used as a dry spool holder.

Who is the Sovol SH03 for

• For hobby and professional users who print often and from multiple materials.
• For users in environments with higher humidity (basements, garages, apartments near water, etc.).
• For everyone who wants to increase print quality, reduce failed prints and extend the life of filaments.

Investment in the Sovol SH03 dryer pays off quickly in the form of more reliable printing, less material consumption and time spent tuning settings.
