Designed for both beginners and enthusiasts, it combines reliable performance, fast printing speeds, and user-friendly operation for a smooth resin printing experience. 9K Print Quality The 7-inch 9K monochrome LCD with 8520 × 4320 resolution and 18 μm XY resolution allows you to print models with extremely fine details and sharp edges at a printing speed of up to 70 mm/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-Engraved Build Plate The laser-engraved build plate provides excellent adhesion during the printing process and makes it easy to remove printed models. Voxeldance Tango Slicer Mars 4 uses Voxeldance Tango Slicer, which offers three printing modes: static mode and dynamic mode (including smooth mode and high-speed mode) to improve printing efficiency and optimize your prints for quality and speed, or a balance of both.The open-source GOO slice file is compatible with third-party slicing software, giving you the freedom to choose the best slicing software for your needs.
