Feature
●【Overview of Neptune 3 Pro】225x225x280mm/8.85x8.85x11 inch market mainstream 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, TPU, PETG, and ABS.
●【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.
●【Smarter Printing Experience】Auto mesh bed leveling adopts a non-contact high precision sensor to automatically scan 36 (6x6) 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) 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.

Description
One-click Auto Leveling
The 36-point leveling system adopts a non-contact sensor to precisely measure the distance between the nozzle and hotbed in 36 areas across the print platform, and automatically calibrates and compensates for any inconsistencies or unevenness of the hotbed for better final print quality.
Powerful Extrusion System
Double-gear direct extruder with 3 times extrusion torque motor and enhanced gearing force, work with titanium alloy throat pipe for easier filament feeding and more stable & precise printing. And the 250W hotbed can quickly heat up to 100ºC, compatible with PLA,ABS,PETG,TPU, and similar filaments.
Quiet & Safe Printing
The whole machine adopts STM 32-bit motherboard silent drivers and a more reasonable nozzle heat dissipation structure, reducing the noise down to 50db, like a persons whisper. Wear resistance POM V-slot wheels move quietly, smoothly, and accurately.
