ELEGOO Neptune 4 Max FDM 3D Printer
[Overview of ELEGOO Neptune 4 Max FDM 3D Printer] 420*420*450mm printing size can meet the needs of most users. With an STM32 motherboard, all axes of ELEGOO Neptune 4 Max FDM 3D Printer 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. 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 (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) 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.
