9K Accuracy with Stunning Detail
The ELEGOO Mars 4 Ultra offers exceptional printing quality and details. It features a 7-inch 9K Mono LCD with 8520*4320 resolution that captures every tiny detail, allowing you to produce highly detailed models with an incredible 18 microns XY precision.

Up to 150mm/h Printing Speed
Mars 4 Ultra’s fast printing capabilities are equally impressive, allowing you to achieve a print speed of up to 150mm/H with ACF release liner film and the upcoming ELEGOO rapid standard resin.

This 3x faster printing speed enables you to produce high-quality models with incredible speed and efficiency.

High-Speed Wifi Transfer
The brand new Linux OS with built-in 4G ROM supports Wi-Fi transfer, with a transmission speed of 6-10Mbps. Plus, it is compatible with both 2.4G and 5G networks, making file transfer a breeze from your computer or mobile device.

The detachable Wifi antenna is conveniently placed on the side of the printer’s Z-axis, making it easy to connect to your network.

COB Light Source + Fresnel Collimating Lens
Experience vertical and uniform exposure of 405nm wavelength beam thanks to the COB light source and Fresnel collimating lens, which provides consistent curing across the entire build area with less than a 5-degree light angle and 92% light uniformity. This ensures that your models have a smooth and even surface finish.

Stable Printing Performance
The Z-axis adopts a linear guide rail structure with an accuracy of 0.02mm, ensuring precise and stable movement to help eliminate riffles on final prints and produce smooth and delicate surfaces on your models.

The 4-point leveling system with four clockwise-tightening screws is design to eliminate the need for repeated leveling after one-time leveling, saving you time and effort.

The build plate has a laser-carved surface to enhance adhesion during the printing process, even when printing large models.

Improved Printing Experience
There is a large cooling fan and heat-conducting copper tubes positioned next to the COB light source for rapid heat dissipation. This feature not only enhances the printer’s performance but also extends its service life.

The upgraded air purifier has a protective plastic case to safeguard the built-in activated carbon filter during transportation and effectively remove resin odor during printing.

The printer comes with Voxeldance Tango Slicer, which offers both static mode and dynamic mode (including smooth and high-speed mode) to improve your printing efficiency. The open-sourced GOO slice file format is compatible with third-party slicing software, such as CHITUBOX and Lychee Slicer.

Leak-proof Design
The printer’s mid-plate is designed with a raised step to keep the resin from flowing inside the printer, which protects the printer’s internal components from damage and ensures a clean workspace.

Screw End Caps for Build Plate Screws
The build platform screws have screw end caps for easier cleaning, which saves your time and effort during post-processing and maintenance.

Adjustable Foot Pads
The adjustable foot pads for improved stability ensure that the printer remains stable on uneven surfaces.
