ELEGOO is a globally recognised leader in consumer and prosumer 3D printing, founded by a team of engineers dedicated to making advanced manufacturing accessible to everyone. Known for combining innovation, reliability, and affordability, ELEGOO develops printers that empower creators - from beginners and educators to professional designers and engineers.
The Neptune series represents ELEGOO's evolution in FDM printing, delivering faster speeds, smarter automation, and improved precision while maintaining user-friendly operation.
With the Neptune 4 range, ELEGOO introduces next-generation high-speed printing powered by modern motion systems and intelligent firmware.
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.
You can easily access the recommended slicing software directly from the ELEGOO Africa website, where the latest version is available for download along with setup guides and supporting resources. This ensures you are working with the most up-to-date software optimised for the Neptune 4 Plus, allowing for a smooth setup process, simplified print preparation, and the best possible printing performance from day one.
