Mars 3 Pro:
[4K 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.
[Powerful 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 smoother surface finish and incredible printing quality.
?Large Build Volume?With a large build volume of 143.43×89.6×175mm (5.647×3.52×6.8 inches), you can print one large model or undergo batch printing in a single job, which saves your time and greatly improves your productivity.
[Designed for Reliability]Non-slip hexagon socket leveling screws work with the sandblasted oxide surface build plate for stronger adhesion and more stable printing. PFA release liner with less release tension for a higher printing success rate.
[Better Printing Experience]The air purifier with a built-in active carbon filter effectively absorbs and filters the resin odor and pungent fumes, giving you a fresh printing experience. Copper heat tubes and a powerful cooling fan with faster heat transfer and better cooling efficiency, extend the life span of a 3D printer.
