Voron2 350

The Voron2 350 is an FDM 3D printer from Voron2 with a 350 x 350 x 350 mm build volume.

Specifications

The Voron2 350 is a prosumer-grade FDM (Fused Deposition Modeling) 3D printer featuring a build volume of 350 mm (X) x 350 mm (Y) x 350 mm (Z). Based on the open-source Voron 2.4 design, the 350 mm variant is the largest standard model in the series, designed for printing large monolithic components from engineering materials without sacrificing the speed advantages of CoreXY kinematics.

CoreXY and Flying Gantry Kinematics (350 mm Specs)

The Voron2 350 utilizes the "Flying Gantry" Z-axis design. In this setup, the heated bed is stationary, bolted to the bottom frame.

Calibration

Follow this 8-step calibration guide to configure the Voron2 350.

• Frame Squaring and Structural Verification

With the 350 mm build volume, frame squaring is critical. Use a machinist's square to check all extrusion joints. Measure the frame diagonals in the X-Y, X-Z, and Y-Z planes.

• Expected result: Diagonal differences under 0.5 mm to ensure a square frame and prevent Z-axis binding.

Common defects

• Hardware defects and mechanical weaknesses
• Gantry Sagging on Power Loss: When the printer is powered down, the flying gantry can drop unevenly under its own weight. This can cause the gantry to bind or twist, loading the belts or rails. Consider installing Z-axis lock mechanisms or configuring Klipper macros to position the gantry safely before shutdown.

What it is used for

Best Use-Cases

• High-Speed ABS/ASA Printing: The enclosed chamber and CoreXY kinematics are suitable for printing ABS and ASA parts quickly without warping [6, 9].
• Large-Format Structural Parts: The 350x350x350 mm build volume allows printing large enclosures, brackets, and robotic parts without sectioning.
