Elegoo Neptune 3 Plus FDM 3D Printer Dual-Gear Direct Extruder 320x320x400mm Larger Bed Size

Main Features of Neptune 3 Plus:

• [Overview of Neptune 3 Pro] 225*225*280mm printing size can meet the needs of most users. With an STM32 motherboard, all axes of ELEGOO Neptune 3 Pro are driven by silent stepper motors for quieter and more precise movement during printing, which reduces the noise as low as 47-48dB. The easy-to-setup printer comes with the main components pre-assembled, as well as a complete tool kit for quick installation.
• [Dual-Gear Direct Extruder] The new dual-gear direct drive extruder is made of SUS303 high-quality stainless steel with a 3:1 reduction ratio and stronger extrusion force for smoother filament feeding and more stable & accurate printing, which greatly reduces nozzle clogging and under-extrusion issues, printing effect is better than Bowden extruder. Compatible with multiple filaments such as PLA, ABS, HIPS, TPU, PETG.
• [Nozzle Kit for Better Printing Effect] The nozzle kit contains a TC4 titanium alloy throat pipe, an aluminum alloy flat heat sink structure, and a brass nozzle. The widened aluminum heat sink paired with the front close-fitting efficient cooling fan for a better heat dissipation effect and lower the temperature of the throat pipe, thereby reducing the possibility of nozzle clogging. Fans on both sides of the print head ensure omnidirectional and rapid cooling of printed layers to improve the model details and overhang printing effect.
• [Smarter Printing Experience] Auto mesh bed leveling adopts a non-contact high precision sensor to automatically scan 36 (6×6) points of the hotbed and collect data in real-time, and then adjust the Z-axis height to compensate for any irregularities and unevenness of the printing platform. (Only applicable to metal printing platforms) Intelligent fan control: after printing, all fans will automatically stop working below 50℃ to extend fan lifespan, reduce noise, and save power. Smart resume printing: the printer will auto-pause when the filament runs out or breaks, and you can resume printing after a power outage.
• [More Stable Printing] The Z-axis with dual synchronized lead screws and dual-motor drive for more stable movement of the print head and higher printing accuracy, avoiding the printing deviation driven by a single Z-axis lead screw motor. The 4-wheel V-guide rail pulley is made of POM with more stable movement, low noise, wear resistance, and longer service life.
• [Ease of Use] PEI magnetic platform with a special coating and spring steel sheet for good adhesion and anti-warping, so that prints can be easily released or popped off by bending the print steel sheet. The 4.3-inch removable capacitive touch screen 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. The 250W high-power hotbed can quickly heat up to 100ºC and start printing. The integrated LED light bar on the gantry can be operated by pressing the buttons on the screen to conveniently observe the model printing in a poor light environment.

One-button Auto Leveling

With a high-precision non-contact sensor to automatically calibrate and compensate for any variances or unevenness at 49-point across the print platform, the bed leveling process is very simple and precise. All you have to do is click the button on the screen, let automatic leveling do its job, and tweaked the Z-axis compensation a bit via the UI. You can also use the hand-leveling knobs underneath the hotbed for auxiliary leveling for better compensation effect and print quality.

Powerful Extrusion Mechanism

The powerful double-gear direct extruder with a 3:1 reduction ratio and enhanced gearing force, paired with titanium alloy throat pipe for fast & smooth filament extrusion and sufficient discharge. The 420W hot bed can be quickly heated up to 100°C to meet the temperature requirements of different filaments, such as PLA, ABS, HIPS, TPU, PETG.

Quiet and Safe Printing

The STM 32-bit silent motherboard and a more reasonable nozzle heat dissipation structure reduce the noise to below 50db. Wear resistance 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.

More Practical Features

The PEI magnetic platform with good adhesion and the printed models can be easily removed by flexing the print steel sheet.

Fans on both sides of the print head ensure omnidirectional heat dissipation and rapid cooling of printed layers. After printing, all fans will automatically stop working to save power, reduce noise, and prolong the fan lifespan.

The removable capacitive screen can be operated by hand or fixed on the machine base and support an 8-language free switch and previewing the printed models.

The LED light strip on the gantry can be operated by the button on the screen to conveniently observe the model printing in a dim environment.
