Incredible Print Quality
ELEGOO Mars 3 Pro comes with a 6.6 inches 4K mono LCD screen with a resolution of 4098*2560 and an XY resolution of 35μm, providing prints with fine details and high precision, which far surpasses FDM printers in quality and speed.
In addition, there is a replaceable scratch-resistant tempered glass above the LCD screen with a perfect fit for better light transmission and protection.

Truly Accurate Printing
Upgraded COB UV LED light source with 36 highly integrated LED lights perfectly matches with Fresnel lens, ensuring the light intensity distribution across the entire screen uniform with consistent accuracy.

PFA Release Liner
With less release tension to better protect the small supports, so that the parts won't stick to the PFA release liner due to excessive suction when printing, thereby improving the printing success rate at a higher level of detail.

High Stability with High Throughput
Sandblasted surface build plate with non-slip hexagon socket screws for quicker and easier leveling, which is more stable for printing bigger models or multiple small parts in one go in a large build volume of 143.43×89.6×175mm³ /5.647×3.52×6.8 in³.


The new heat dissipation system includes double heat-conducting copper heat tubes and a cooling fan for faster ventilation and heat dissipation, with less than 5% light decay after 6000 hours of continuous printing.

The activated carbon filtration system can effectively reduce the divergence of odor for a refreshing printing environment.

Support both Chitubox Pro slicer and Lychee Slicer 3.0 software. New features are added to Chitubox Pro software, such as an automatic support algorithm, model repair tool, easy object manipulation, and many other functions to realize the infinite possibilities of 3D printing.
