Snapmaker 2 A350 Dual Extruder

The Snapmaker 2 A350 Dual Extruder is an FDM 3D printer from Snapmaker with a 310 x 330 x 290 mm build volume.

Specifications

Based on comprehensive technical reviews and manufacturing data, here are the verified technical specifications of the Snapmaker 2 A350 3-in-1 3D printer equipped with the Dual Extrusion Module:

• Hotend: The dual extrusion module is designed as an all-metal, high-temperature system capable of reaching a maximum operating temperature of 300°C. This wide thermal range enables the extrusion of not only standard consumer plastics like PLA, PETG, and flexible TPU, but also demanding engineering polymers such as Copolyester, Polycarbonate (PC), Polyamide (Nylon/PA), and carbon-fiber or glass-fiber reinforced filaments (PA-CF, PA-GF).

Calibration

Achieving flawless prints with the Snapmaker 2 A350 Dual Extruder requires meticulous calibration. Because the two nozzles are physically fixed on the same carriage, any alignment errors will lead to print defects, dragging, or mixing colors. Follow this step-by-step engineering calibration cookbook:

• Thermal Stabilization and Bed Degreasing:
• Procedure: Clean the PEI build plate thoroughly with high-purity Isopropyl Alcohol (IPA, >90%) using a lint-free microfiber cloth.

Common defects

• Hardware defects and mechanical weaknesses
• Heat Creep and Clogging in the Compact Carriage: The compact packaging of the dual extrusion toolhead restricts air volume around the heatsinks. When printing low-temperature filaments like PLA or water-soluble PVA, the heat from the active heater block can migrate up the metal heat break into the heatsink. This causes the filament to soften prematurly in the cold zone, causing it to swell and clog the extruder.

What it is used for

Best use-cases:

• Complex Geometric Assemblies with Soluble Supports: The Dual Extruder is highly effective for printing parts with intricate internal cavities, steep overhangs, or interlocking mechanical parts.
