Elegoo Neptune 4 Pro
Main features:
- Intelligent Segmented Heatbed - With 100W + 150W power output, 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. Additionally, the surface of the PEI magnetic platform is marked for guidance.
- All-metal linear rails - Both the X and Y axis use all-metal rails to withstand heavy use, with U-shaped steel wheels for less drag and more precision.
- Pre-installed Klipper Firmware - With a quiet Klipper motherboard and ARM 64-bit 1.5G main frequency quad-core high-performance processor, Elegoo Neptune 4 Pro can achieve printing speed of up to 500mm/s (recommended 250mm/s), allowing you to produce your models faster than ever before. Neptune 4 Pro supports input shaping and pressure advance function to improve the print quality of models.
- Dual-Gear Direct Extruder - The new self-developed dual-gear direct drive extruder with a 5.2:1 reduction ratio ensures powerful extrusion and smoother filament feeding. Paired with copper-titanium all-metal throat pipe and unique air duct design to effectively improve the heat dissipation of the throat pipe and reduce nozzle blockage risk.
- 300°C High-temp Nozzle - With a 300°C high-temp nozzle and an extended hot end, which means the filament can be fully melted and uniformly flow out even at high printing speed, this printer can handle a wide range of materials, including PLA, PETG, ABS, TPU, and high-temperature filaments such as nylon.
- Auto Bed Leveling + Auxiliary Leveling - With 121 (11x11) points auto bed leveling, you can achieve consistent and reliable prints every time without the need for manual bed leveling. Additionally, the auxiliary leveling by hand-twist knobs allows for further fine-tuning of the print bed's level for improved print quality.
- Efficient & Instant Cooling - The 2 thickened double-sided 4015 model cooling fans with strong wind for more comprehensive and efficient heat dissipation, along with the 4x4020 ball bearing blower fans behind the print head to quickly cool down the newly deposited model, ensuring good print quality even at very fast printing speed.
- Removable Capacitive Touchscreen - The 4.3-inch removable capacitive touchscreen can be operated by hand-held or fixed on the base, and features a model preview function and pause printing function for added convenience. The gantry's LED light strip with 30 beads and a hood, combined with an LED light on the nozzle for observing the model printing in a dark environment.

Separate Segmented Heatbed Elegoo Neptune 4 Pro features an intelligent segmented heatbed for added efficiency and energy-saving, and a hot bed overheat protection switch to prevent thermal runaway causing hot bed damage or fire. The heatbed can be set to 100W to heat only the center area (120 mm x 120 mm), making it ideal for smaller models. For larger models, the heatbed can be set to 250W, heating the entire surface area. The two partitions can also be manually controlled for flexible temperature adjustments. PEI magnetic platform with a special coating and spring steel sheet for good adhesion and anti-warping, just gently bend the print steel plate to release or pop off the prints. |

Unparalleled Heat Dissipation PerformanceIn addition to the two thickened 4015 ball bearing cooling fan on both sides of the print head, there are four 4020 ball bearing auxiliary fans behind the print head, which ensures omnidirectional rapid cooling of the newly printed layers even at a fast printing speed, and the deposited hot filament quickly bond together for better overhang and bridge results. |
Potent Extrusion & Upgrade HotendThe dual-gear direct extruder with a 5.2:1 reduction ratio and enhanced gearing force for even filament extrusion and sufficient discharge, weighing only 75% of the weight of the Neptune 3 Pro. Copper-titanium bi-metal throat pipe with unique air duct design for faster heat dissipation and less nozzle clogging. The nozzle with an extended hotend can withstand up to 300°C to fully melts the filament, meeting the temperature requirements of high-temp filaments like nylon. |

More Practical Features
- no more worries about unexpected power failure during printing since the printer can resume printing after the power is restored
- whenever the filament runs out or breaks, the printer will pause and alarm you to prevent wasted materials and scrapped models
- supports LAN networking printing, so once connected, you can use the WEB terminal to remotely control and monitor your printer
- the XY-axis belt tensioner is easy to adjust with a hand-twist knob, and the widened Y-axis profile ensures a stable printing platform
- the removable capacitive screen can be handheld or fixed on the machine base, supporting 8 languages, print models previewing, and a pause printing function
- the gantry's LED light bar and nozzle LED light can be operated via the screen's button to conveniently monitor printing progress even in dim lighting
