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.

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 FAST 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 RAM 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.
