V-wheel drive: The V-wheel is made of imported POM material, which has the advantages of ultra-quiet, high precision, and wears resistance. At the same time, the machine transmission mechanism is equipped with an eccentric isolation column, which can make up for the reduction of printing accuracy caused by long-term printing and wear of the V wheel;

The Mars 4 has been safeguarded against unforeseen errors. Its front platform is slightly stepped, in case of resin leakage. Large Build Volume] With a large build volume of 143×89.6×175mm (5.62×3.52×6.8 inches), you can print one large model or undergo batch printing in a single job, which saves your time and greatly improves your productivity. PS: After printing all the firmware files, you need to restart the machine to make the new firmware take effect. Smart Voxeldance Tango Slicer 】 Three printing modes are optional: static mode and dynamic mode (including smooth and high-speed mode). In dynamic mode, the slicing software will dynamically adjust the printing speed by the cross-sectional size of the printed model to reduce the impact of the release force, thereby improving the printing efficiency. In addition, ELEGOO self-developed a new open-source GOO slicing format, which is compatible with multiple slicing software without restriction. Inch 9K Mono LCD】Equipped with a 7-inch 9K mono LCD offering an impressive 8520x4320 resolution and 18µm XY resolution, Mars 4 Ultra allows you to print incredible complex models with crisp details. The mono LCD is protected by a 9H hardness tempered glass, ensuring it withstands daily wear and tear while maintaining optimal performance.Smart resume printing: the printer will auto-pause when the filament runs out or breaks, and you can resume printing after a power outage.

ELEGOO 3D Printer, Neptune 3 Plus FDM 3D Printer with 49-Point Auto Bed Leveling, Dual-Gear Direct Extruder, Ultra-Quiet Printing, Removable Capacitive Screen, Larger Printing Size of 320x320x400 mm / 12.59x12.59x15.74 Inches Removable Capacitive Touchscreen】The 4.3-inch removable capacitive touchscreen can be operated by hand-held or fixed on the base, and features a model preview function and pause printing function for added convenience.

Fast and accurate, the Elegoo Mars 3 is the latest and greatest in the Mars series of printers.

Powerful Linux OS】With built-in 4G RAM and no more delay loading files, the Linux operating system ensures faster & smooth operation and efficient resource management. Material break detection and material shortage alarm: to avoid the machine running empty when the consumables are used up, resulting in material waste and model scrap; Dual-Gear Direct Drive Extruder】The dual-gear direct drive extruder with a 5.2:1 reduction ratio for smooth and consistent extrusion, combined with the copper-titanium bi-metal throat pipe and unique air duct design, improve heat dissipation and reduce nozzle clogging. 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. Monochrome LCD] 6.6-inch 4K monochrome LCD screen with a replaceable anti-scratch tempered glass with 9H hardness for a better light transmittance at 4098 x 2560 high resolution, protecting the screen while restoring model details to the greatest extent.

The Mars 4 is equipped with a special heat-conducting copper heat pipe for faster heat transfer, as well as a large fan* for more efficient heat dissipation.

Upgraded light source】 36 highly integrated LED lights with a brand new COB lens that has a free-form surface can deliver over 90% uniformity of UV light illumination, making the printing accuracy upgraded to another level. Hours Lifespan 】 The service life of the DLP projector is as long as 20,000+ hours, 10 times longer than the 2,000 hours lifespan of an LCD screen, which means you will save a lot of maintenance costs for replacing your LCD printer's screen.

The Elegoo Mars 3 Pro is equipped with a replaceable 9H tempered glass screen protector that protects the monochrome display. Neptune2s adopts a new platform of a special coating combined with spring steel, easy model removal by bending or popping. It is not easy to deform at high temperature, detachable, and has a longer service life.Widely compatible with PLA/ABS/PETG/TPU filaments. The new FEP 2.0 facilitates removal and the print quality is increased due to its high UV light transmission. Large Build Volume】The 153.36x77.76x175 mm³/6.04x3.06x6.89 inch build volume provides you with enough space for daily creations without sacrificing printing accuracy. you only need to update the files in the firmware file and copy the files to the root directory of the diskPowerful COB Light Source] Upgraded free-form surface COB lens consists of 36 highly integrated UV LED lights, paired with a Fresnel lens to deliver an even beam of 405nm wavelength with 92% light uniformity for a more smooth surface finish and incredible printing quality. COB+ Refractive Light Source】MARS 4 Max adopts the COB+ refractive light source to ensure that the emitted 405nm wavelength beam is more vertical and uniform on the entire LCD screen after refraction. Paired with the full grayscale anti-aliasing algorithm to make printed models with finer and more realistic details and a smoother surface. A step design of the center platform prevents leaking resin from flowing into the interior of the device, damaging its internal components. C. Intelligent fan system, which automatically shuts down after cooling, prolongs the life of the machine . Effortless Leveling】The 4-point hassle-free leveling system makes setup a breeze, and after one leveling, no need to repeat leveling, ensuring perfect prints every time. The laser-carved surface on the build plate offers improved adhesion, reducing the risk of print failures. Brand new ACF release liner film with less release tension for a high printing success rate even at a faster printing speed.
