Elegoo Neptune 3 Max represents a revolution in 3D printing with a huge printing space of 420 x 420 x 500 mm and a Dual-Gear extruder for smooth printing of materials such as PLA, PETG and TPU. It uses automatic print bed alignment with 63 control points and a quiet 32-bit motherboard for quiet printing below 50 dB. More
Elegoo Neptune 3 Max
Main features:
- Dual-Gear Direct Extruder - The new dual-gear direct extruder with gears made of SUS303 stainless steel features adjustable extrusion force and a 3:1 reduction ratio, which greatly reduces the risk of nozzle blockage and under extrusion, and printing well with PLA, ABS, PETG and even flexible filaments like TPU.
- Massive Print Volume - With the largest ever print volume of 420 x 420 x 500 mm, Neptune 3 Max gives you generous printing space to let your creativity run wild, whether you're printing larger models, or batches of smaller models.
- Auto Bed Leveling + Auxiliary Leveling - The non-contact high precision sensor automatically scans 63 points of the hotbed to compensate for any unevenness and inconsistencies of the printing platform. You can also use the hand-twist knobs under the build platform for auxiliary leveling to achieve the perfect first layer.
- Stable & Quiet Printing - The Z-axis is designed with dual lead screws and dual-motor drive for more stable and precise movement of the print head, and the double tie rod structure enhances the stability of the Z-axis gantry. With an STM 32-bit silent motherboard, the X/Y/Z/E axes are all driven by high-precision stepper motors to effectively reduce the printing noise under 50 dB.
- PEI Magnetic Platform - PEI magnetic platform with 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. The 420W high-power hotbed can quickly heat up to 100°C.
- Removable Capacitive Touchscreen - The 4.3-inch removable capacitive touchscreen can be operated by hand-held or fixed on the base. Built-in print model preview function to preview the model image before printing, and observe the printing progress by previewing the real-time comparison image of the printed model.

One-button Auto Leveling
The 63-point leveling system adopts a non-contact sensor to automatically calibrate and compensate for any inconsistencies or unevenness. No more tedious leveling operations of the printing platform. Simply click the button on the screen to start the automatic leveling job! There are hand-leveling knobs under the hotbed to fine-tune the build platform for a better compensation effect and final print quality. |

Potent Extrusion & Efficient Heat Dissipation The dual-gear direct extruder has powerful and adjustable extrusion force and better grip on the filament, paired with titanium heatbreak to achieve a smooth & even filament feeding. Widened aluminum heatsink and efficient front cooling fan for faster heat dissipation of the heatbreak, thus reducing nozzle clogging risk. Fans on both sides of the print head ensure omnidirectional and rapid cooling of printed layers for better overhangs and bridges printing results. |
|
Print Quietly and Safely The STM 32-bit silent motherboard and a more reasonable nozzle heat dissipation structure reduce the noise to below 50 dB. Wear resistant POM V-slot wheels move quietly, smoothly, and accurately. The 500W wide voltage power supply does not need to be adjusted and can be automatically switched according to the input voltage to ensure printing safety. |

Enhanced Stability Structure Z-axis dual lead screw+Z-axis dual-motor design with better synchronization increases the accuracy and stability of printing. The double tie rod structure enhances the stability of the Z-axis gantry. The XY-axis belt tensioner is easier to adjust belt tightness by rotating the hand-twist knob, and the Y-axis components are guided by dual profiles to improve the balance of the Y-axis and the stability of the printing platform. |
|
Smart Resume Printing No worry about unexpected power failure during the printing process since the printer can resume printing after the power supply is restored. With a filament detection sensor, whenever the filament runs out or breaks, the printer will pause and alarm until you load the new filament to avoid material waste and model scrapping. |
