Please fill the resin tank no less than 1/3 of its volume, but do not exceed the MAX line position. Please place the printer in a dry environment and protect it from rain and moisture. If you run into an emergency during use, please turn off the power supply of the 3D printer first. Please use the printer indoors and avoid direct sunlight and a dusty environment. Please use 95% (or higher) ethyl alcohol or isopropyl alcohol to wash your model unless you are using water washable resin. If the printing fails, you need to clean the excess cured resin in the resin tank and change the resin, otherwise, it may cause damage to your printer. When operating the 3D printer, please wear a mask and gloves to avoid direct skin contact with the photopolymer resin. If the release film in the resin tank is whitened, scratched, or has no elasticity, the printing failure rate is high, please replace the release film in time. - 7Inch 9K LCD Screen The Mars 4 Ultra 9K printer uses a 7-inch LCD screen with a resolution of 8520*4320, the printing speed can reach up to 150mm/h with ACF release film and ELEGOO rapid standard resin. A tempered film with a hardness of 9H is added, which can effectively prevent the leakage of resin liquid from leaking. - COB+Fresnel Collimating Light Source Using a new COB light source and Fresnel lens design, the light angle is within 5, and the model details are more realistic. The heat dissipation performance is more efficient, effectively prolonging the service life of the printer. - Laser Carved Platform The laser carved platform and the Z-axis linear guide rail have strong adhesion to the model, which makes the operation more stable, effectively reduces the pattern of the model, and improves the success rate of model printing. The printing size is 153.36mm*77.76mm*165mm. Four-point leveling design is easy to operate, just one leveling. - User Friendly Design The Linux operating system makes file transfers more stable and faster. Upgraded to a 4-inch high-definition IPS touch screen, a new UI interface design. Files can be transferred without plugging in USB, and WIFI transfer can be realized. Equipped with intelligent Voxeldance Tango slicing software. The new open source GOO slicing format is compatible with a variety of slicing software. - Printing TipsSuggestions for ensuring successful printing and protection of the LCD screen/release film: Before printing, please ensure that the parameters of the machine are correctly debugged. Add the model support correctly in the slicing software and improve proficiency in the use of slicing software. Clean up the resin tank in a timely manner after printing.
