Cubicon Style Neo-A31

The Cubicon Style Neo-A31 is an FDM 3D printer from Cubicon with a 310 x 310 x 310 mm build volume.

Specifications

The Cubicon Style Neo-A31 (technical designation Style NEO-A31C) is the largest and most robust enclosed professional FDM 3D printer in the Style product family by South Korean manufacturer Cubicon. Launched alongside the Neo series, this printer is designed for industrial prototyping, large-scale prints, and low-volume production runs in engineering offices, factories, and universities that require a large build volume and process automation.

The mechanical specifications of the Cubicon Style Neo-A31 feature a build volume of 310 x 310 x 310 mm, representing an expansion over the smaller A22 model (220 mm) and positioning it as a competitor to high-end industrial printers.

Calibration

To achieve optimal print quality and dimensional accuracy on large prints using the Cubicon Style Neo-A31, complete these 8 calibration steps:

• Large Bed Degreasing and Cleaning

Due to the large build surface area (310x310 mm), dust and skin oils can accumulate easily. Clean the cold bed before printing using 99% or higher Isopropyl Alcohol (IPA) and a lint-free paper towel. Avoid using acetone, as it can damage the micro-texture of the ceramic coating.

Common defects

• Hardware defects and mechanical weaknesses
• Z-Drag Chain Cable Fatigue:

Due to the large travel distances along the X/Y/Z axes (310 mm), the printhead wires are routed through a plastic drag chain. Over time, the cables in the high-flex zones can develop wire fractures, leading to temperature sensor faults or extruder motor stalling.

Fix: If "Heater Open" errors occur, replace the cable harness with an OEM replacement or use high-flex silicone-insulated wiring.

What it is used for

Best use-cases

• Large ABS and ASA Parts:

The 310 mm build volume and enclosed chamber make the printer well-suited for printing large enclosures, brackets, and automotive prototypes without warping.

• STEM Labs and Universities:

The fully enclosed chassis, safety door sensors, and HEPA air filtration make it safe and accessible for educational use.
