Sovol-SV02 (Legacy)

The Sovol-SV02 (Legacy) is an FDM 3D printer from Sovol 3D with a 240 x 220 x 300 mm build volume.

Specifications

Based on official product manuals, user forums, and technical specifications, here are the verified specifications of the Sovol SV02 (Legacy) dual-extrusion 3D printer:

• Hotend: The defining characteristic of the Sovol SV02 is its "2-in-1-out" dual extrusion hotend system. This setup utilizes two independent Bowden extruder motors mounted on the frame that feed filament into a single heater block and nozzle. Inside the hotend, a Y-shaped metal transition chamber merges the two filament paths. The maximum hotend temperature is 250°C.

Calibration

Successful dual-color printing on a 2-in-1-out hotend depends entirely on how well the filament tip is shaped and retracted. If the filament is not retracted properly, it will form a bulbous tip (blob) inside the Y-splitter, blocking the secondary filament from loading and ruining the print.

• PTFE Bowden Tube and Fitting Inspection:.

Common defects

• Hardware defects and mechanical weaknesses
• Y-Splitter Clogging: The primary mechanical weakness of the SV02 is clogging inside the Y-splitter. If the retracted filament tip is deformed or too thick, it will jam inside the metal split junction. This often results in the filament snapping inside the hotend, requiring complete disassembly of the toolhead to clear.

What it is used for

Best use-cases:

• Dual-Color PLA or PETG Decorative Models: Ideal for printing signs, nameplates, multi-color logos, and detailed decorative figures. The lightweight toolhead ensures very smooth wall finishes with minimal ringing.
