ELEGOO Neptune 2D 3D Printer generates 220X220X250mm sized prints at a speed of ~180 mm/s. It has 8.66*8.66*9.8 inches build dimensions, a user-friendly interface, operates at low decibels, and is safest to use by children, novices, and professionals.


ELEGOO Neptune 2D 3D Printer is a semi-assembled, simplest-to-operate device, made up of POM material that has supreme wear resistance, is ultra-quiet and has a high precision (±0.1mm).

It’s a smart printing device that automatically shuts off the power supply after the model, saving electricity.

The resume printing option is another safety feature that enables the printer to pause at an accidental power or filament outage and resume printing from the same layer.

The Auto-Stable power supply system (400 Watt) automatically went to the switched mode when the machine reached its desired temperature and prevented it from getting hotter.

Its 250W hotbed is highly-efficient and fast. It heats the hotbed to its maximum degree in less than 3 minutes.

ELEGOO Neptune 2D offers a multi-language user interface, large rotary nuts for easier leveling, a TMC2225 silent driver for quitter printing, and consistent printing for more than 2,000 hours.

Not only that, this 3D printer’s hotbed is made up of replaceable fiberglass that allows stronger adhesion and smooth removal of the model once it completes.

    This 3D printer is semi-assembled, making it easier to setup and operate. The silent motherboard is an exciting feature. The printer has 32-bit with a TMC2225 silent driver that allows you to enjoy a quiet printing environment. Two all-metal extruders also back the printer for automatic dual color filament.

    The printer comes semi-assembled. Although there’s a bit of work involved in assembling, it can be completed in under an hour. The bed is leveled manually but it’s not particularly difficult. Filaments adhere nicely to the plate without glue and prints can easily be removed.

    I would recommend this printer because you can mix colors while printing thanks to all-metal extruders for automatic dual color filament. it has a paused print feature. I found little faults in this printer and it can deliver high-quality prints with accuracy and the least amount of noise.

    This printer can deliver high-quality prints with great precision. The 3D Printer is equipped with two extruders; it supports automatic dual color filament switching in a single nozzle. Two all-metal gears equipped on each extruder provide better and more accurate prints.32bit motherboard with TMC2225 silent driver provides a quieter printing at 50db noise level and ensures consistent printing for 200 hours without any issues. I like this printer because of the features mentioned above, coupled with the fact that the printer has Safety Power Supply, Resume Printing and Removable Build Plate with 220x220x250mm Printing Size.
