Neptune 4 Plus 3D Printer

The ELEGOO Neptune 4 Plus expands high-speed FDM printing into large-format production while maintaining precision and reliability. Powered by Klipper firmware and a reinforced motion system, the Neptune 4 Plus enables creators to produce larger parts faster without sacrificing print quality.

Featuring an all-metal hotend, intelligent automatic bed levelling, and an upgraded cooling system, the printer is designed for demanding workflows such as prototyping, cosplay components, functional parts, and batch production. The larger build volume, combined with high-speed performance, makes the Neptune 4 Plus ideal for makers ready to scale beyond standard desktop printing sizes.
