Accelerate Printing with Klipper

With the Klipper motherboard and a quad-core ARM 64-bit 1.5G main frequency processor to process and execute commands faster, the Neptune 4 Pro can print at up to 500mm/s, allowing you to complete your printing projects quickly and efficiently. With our pre-installed Klipper firmware, you can start printing right away without the hassle of firmware installation.

Additionally, 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 uniform extrusion and less filament ooze and blob formation.

Powerful Extrusion & Improved Hotend

Another key feature of the printer is the dual-gear direct drive extruder, which 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 flexible filament from slipping and grinding. The copper-titanium bimetal throat tube has an exclusive air duct design for faster heat dissipation of the throat tube and less nozzle clogging.

The 300 °C high-temperature 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-temperature filaments like nylon.

*Tip: For printing ABS, ASA, and Nylon filament materials, it is recommended to use a printer with an enclosed chamber or a dedicated enclosure. These materials require a thermally stable printing environment; an enclosed chamber helps reduce warping, improve surface quality, and limit the dispersion of fumes and odors during printing.

Unrivalled 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, ensuring rapid and omnidirectional cooling of newly printed layers even at high print speeds, while the hot deposited filament quickly binds 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 less than 50 dB. Its wear-resistant POM V-guide wheels move silently, smoothly, and accurately.

The dual lead screw design on the Z-axis and dual motor on the Z-axis ensure better synchronization, increasing the accuracy and stability of print head movement.

Smoother Model Surface

Support for advanced features like input shaping and pressure advance helps achieve a smooth model surface and consistent extrusion.

Smart Segmented Heated Bed

With a power output of 100W + 150W, the slicing software automatically recognizes the model size during operation and activates the peripheral heating zone if the model size exceeds the central heating zone (120mm x 120mm).

For more precise temperature control, you can manually turn the two partitions on and off.

Additionally, the magnetic PEI platform surface is marked for guidance.
