Elegoo Neptune 4 Plus | Large-Format FDM 3D Printer | 500mm/s

Large-Format Speed. Automatic Levelling. Klipper Out of the Box.

The Elegoo Neptune 4 Plus is built for makers, small businesses, and professionals who need more build volume, more speed, and less time spent on calibration. With a 320 × 320 × 385 mm build area, Klipper firmware pre-installed, and automatic bed levelling as standard, it delivers large-format performance without the setup overhead.

Print speeds run at a standard 250 mm/s and push up to 500 mm/s — backed by accelerations up to 12,000 mm/s² and a reinforced Y-axis that keeps quality consistent even at high speeds. The dual-gear direct drive extruder handles a wide variety of filaments reliably, while the improved cooling system and 300°C maximum nozzle temperature give you the headroom to work with demanding materials that lower-spec machines can't touch.

Klipper gives you full access to input shaping, pressure advance, and advanced tuning — the tools that experienced users rely on to extract the best possible performance from every print. And for those new to Klipper, the Neptune 4 Plus makes a genuinely good introduction.

Built for enthusiasts, small businesses, and professionals who need to:

• Print large architectural scale models, display pieces, and presentation prototypes
• Run batch production — print multiple parts simultaneously across the full build plate
• Create full-scale cosplay armor, helmets, and large-format accessories
• Manufacture functional enclosures, production-ready prototypes, and custom tooling
