Elegoo Neptune 4 Pro

Fast, stable and powerful, the Neptune 4 Pro is a great addition to the Elegoo family. The FDM printer is equipped with a high-performance, high-speed mainboard, reaches an incredible top speed of 500 mm/s, and is compatible with Klipper!

Neptune 4 Pro compared to Neptune 4

While the printers have broadly similar features, there are three fundamental differences that make Neptune 4 Pro stand out:

► Heating bed with two heating areas: Both printers are equipped with a 250-watt heating bed. However, the Neptune 4 Pro's smart heating bed has two independent heating areas (150 watts + 100 watts).

► All-Metal Frame

► All-Metal Linear Rail

Stable design with a modern look

Neptune 4 Pro uses a portable and stable gantry structure with elegant and modern elements.

High speeds

The FDM printer uses a high-performance computing processor that allows it to reach a top speed of an incredible 500 mm/s! Elegoo recommends a standard print speed of 250 mm/s for best printing results.

The processor has a special motion control algorithm that can calculate the step time with high precision for higher motion accuracy.

Klipper-compatible high-speed silent mainboard

The powerful ARM 64-bit 1.5G quad-core High-Speed Silent mainboard not only ensures quiet operation but also effectively reduces printing noise. In addition, it has 8G of memory and supports the secure storage of more than 400 model files.

Unlike other printers in the Neptune line that are compatible with Marlin, Neptune 4 and Neptune 4 Pro come with Klipper firmware.

Large build volume for more creativity

Just like its brother the Neptune 4, the Neptune 4 Pro is built in the popular FDM 3D printer build volume of 225 x 225 x 265 mm. This allows the most creative 3D ideas to be turned into reality.

All-Metal Guide Rails

Both the X and Y axes use robust all-metal guide rails with U-shaped steel wheels to ensure less drag and more precision.

250-watt heated bed with two independent heating areas

Both the Neptune 4 and Neptune 4 Pro feature a 250-watt heating bed that heats up to 110 °C in just a short time. The main difference between the two is that the smart heating bed of the Neptune 4 Pro has 2 independent heating areas: While one operates at 100 watts, the other heats at 150 watts. With this clever system, you can significantly reduce power consumption, since only the area that is needed for the size of your model is heated.

When editing and setting parameters in the slicer, you can turn on the "intelligent mode". This automatically detects the size of your model and heats either only one heating area if you are printing a smaller model, or both heating areas if you are printing models of different sizes at the same time. The heating areas can of course also be controlled or set manually on the screen.

PEI magnetic build platform

Thanks to the special PEI coating, printed models can be easily detached from the build platform without any tools after the heating bed cools down.

Self-developed dual-gear extruder with direct drive

Elegoo's proprietary Dual Gear Direct Drive extruder of the Neptune 4 Pro is 25% lighter than the extruder of the Neptune 3 Pro. It ensures greater extrusion force, resulting in a 5.2X extrusion ratio and higher printing accuracy.

A wide range of materials such as PLA, ABS, TPU, nylon, etc. are supported.

High Temp Hotend for temperatures up to 300 °C

The hotend of the Neptune 4 Pro supports temperatures up to 300 °C. It features an all-metal high-temperature heat break and a unique air channel design for better heat dissipation.

The hot end of the nozzle has been extended to allow filaments to be fully melted and evenly extruded.

Powerful cooling system

The Neptune 4 Pro, like its twin brother Neptune 4, is equipped with a sophisticated cooling system. This combines a heat dissipation module with intelligent fan control, which ensures comprehensive heat dissipation during printing:

• 4 powerful 4020 fans dissipate heat during high-speed printing at a max rotation rate of 10,000 rpm;
• 2 side-mounted 4015 fans cool the model during printing at a max speed of 11 000 rpm;

An intelligent fan control automatically turns off all fans after printing, not only saving energy but also reducing noise levels.

Manual or 2.0 automatic levelling - the choice is yours

Neptune 4 Pro features a high-precision, non-contact levelling sensor that automatically acquires data from 121 points (11 x 11) on the build platform, increasing printer success rates.

Smart features for more clearance and flexibility

► Filament Detection Sensor: If a breakage occurs or you run out of filament, an error alarm is automatically triggered as well as the printing process is interrupted to prevent errors on the model or filament waste.

► Smart Resume Printing: In the event of a power failure, printing will resume as soon as power is restored.

Capacitive 4.3-inch screen

You can either attach the magnetic 4.3-inch touch screen to the printer base or hold it comfortably in your hand.

Multiple languages are supported: simplified Chinese, English, Spanish, French, Italian, Russian, German and Japanese.

Printing over LAN networks

Whether remote control or monitoring - you always have your printing process in view via the WEB terminal!

Easily operated X/Y-axis belt tensioner and wider Y-axis for more precise movements

Set the optimal belt tension by operating a knob

The widened profile of the Y-axis (to 56 mm) provides more stable and smooth movements.

Double Z-axis motor with leadscrews

Neptune 4 Pro uses two powerful Z-axis motors with leadscrews for better print quality and higher precision.

LED light for a better view

Daylight is great, no one disputes that. But your great 3D-printed models deserve to be shown off in a special light! That's why the Neptune 4 Pro has been equipped with LED lights: one LED light is located right next to the nozzle; there's also a light bar with 30 LED lights on the top of the printer frame. Both LED lights can be switched on and off very easily on the touchscreen.
