6K Printing Accuracy
With a 9.1-inch 6K mono LCD screen of 5760x3600 resolution, you can print out highly detailed models at 34 microns XY resolution, with a faster printing speed of up to 70mm/H and a curing time of only 1.5-3s per layer.
The replaceable tempered glass with 9H hardness effectively prevents scratches and damage to the LCD screen and prolongs its lifespan of LCD screen.

Smoother Surface Finish
The COB+ refractive light source ensures that the exposure of the 405nm wavelength beam across the LCD screen is more even and vertical with consistent accuracy.
Combined with full-grayscale anti-aliasing algorithms, which significantly reduces the "staircase" effect, resulting in finer details and a smoother surface finish.

Dual Cooling Fan Design
The dual cooling fan structure dissipates heat faster and more efficiently, thereby extending the service life of MARS 4 MAX.

Multiple Printing Modes
The Voxeldance Tango Software provides 3 printing modes: static mode and dynamic mode (including smooth mode and high-speed mode). When selecting the dynamic mode, it will adjust the printing speed dynamically according to the cross-sectional size of the printed model, which reduces the influence of release force and improves printing efficiency.
Besides, ELEGOO has self-developed a new open-source GOO slice format, which is compatible with third-party slice software, such as CHITUBOX and Lychee Slicer.


The 20mm thicker Z-axis linear guide rail effectively reduces the vibration amplitude during Z-axis movement and the layer pattern of printed models for a better printing effect.

The sandblasted build plate increases model adhesion for a higher printing success rate.

The air purifier is connected via USB, with an activated carbon filter to reduce resin odor in the printer chamber. You can also choose the upcoming ELEGOO's first large air purifier, which can remove formaldehyde and up to 95% of VOCs.
