9K Print Quality: The 7″ 9K monochrome LCD with 8520×4320 resolution and 18×18? XY resolution allows you to print models with extremely fine details and sharp edges at a printing speed of up to 70mm/h, achieving superior quality and precision. Powerful COB Light Source: Mars 4 adopts a powerful COB light source consisting of 36 LEDs hidden beneath a monochrome LCD that work together to provide a highly uniform UV light beam throughout the build area. The result is your printed models with exceptional precision and smooth surfaces. Efficient Heat Dissipation: With a large cooling fan and heat-conducting copper tubes next to the COB light source for fast heat transfer, this ensures efficient heat dissipation performance and prolongs the service life of the printer. Laser-Carved Build Plate: The laser-engraved build plate provides excellent adhesion during the printing process and easy to remove printed models.
