Speed Up Printing with Klipper
With the Klipper motherboard and ARM 64-bit 1.5G main frequency quad-core processor to process and execute commands faster, Neptune 4 Pro can print at up to 500mm/s, allowing you to complete your print projects quickly and efficiently. With our pre-installed Klipper firmware, you can start printing right away without the hassle of firmware installation.
In addition, it supports input shaping, which helps eliminate artifacts and resonances on the model surface, and pressure advance, which helps predict nozzle pressure for more accurate and consistent extrusion and less filament ooze and blobbing.
Potent Extrusion & Upgraded Hotend
The printer's dual-gear direct drive extruder is another key feature that ensures smooth and consistent extrusion, weighing only 75% of the Neptune 3 Pro.
The 5.2:1 reduction ratio and dual-gear design ensure a firm grip on the filament and prevent the flexible filament from slipping and grinding. The copper-titanium bi-metal throat pipe has a unique air duct design for faster heat dissipation of the throat pipe and less nozzle clogging.
The 300 °C high-temp nozzle features an extended hotend design to fully melt the filament, allowing you to explore a wider range of materials, such as PLA, PETG, ABS, ASA, TPU, and high-temp filaments like nylon.
Unparalleled Heat Dissipation Performance
In addition to the two thickened 4015 ball bearing cooling fans on both sides of the print head, there are four 4020 ball bearing auxiliary fans behind the print head, which ensure omnidirectional rapid cooling of the newly printed layers even at a fast printing speed, and the deposited hot filament quickly bonds together for better overhang and bridge results.
Stable & Quiet Printing
The ELEGOO Neptune 4 Pro 3D printer is designed for quiet and precise printing with its silent drivers for all axes, reducing noise to below 50 dB. Its wear-resistant POM V-guide wheels move quietly, smoothly, and accurately.
The Z-axis dual lead screw + Z-axis dual motor design provides better synchronization, increasing the accuracy and stability of the print head movement.
Smoother Model Surface
Support for advanced functions like input shaping and pressure advance helps achieve a smooth model surface and consistent extrusion.
Intelligent Segmented Heatbed
With a power output of 100W + 150W, the slicing software automatically recognizes the size of the model during slicing and activates the peripheral heating zone if the model size exceeds the center heating zone (120 mm x 120 mm).
The two partitions can also be turned on and off manually for more precise temperature control.

Upgraded Dual-Sided Build Plate
The upgraded dual-sided plate ensures perfect PLA prints with a new specialized PLA Surface for excellent adhesion and minimal warping even at lower heatbed temperatures.
The original Textured PEI Surface ensures strong adhesion and easy print removal, supporting materials from PLA and TPU to high-temp options like ABS and carbon fiber.
Intelligent 3D Printing
No worries about unexpected power failures during printing, since the printer can resume printing after the power supply is restored.
Whenever the filament runs out or breaks, the printer will pause and alert you to prevent wasted materials and scrapped models.
Supports LAN Networking Printing
After connecting your printer to the LAN, you can easily access the web terminal for remote control and monitoring.
