The LCD screen is the flat-panel display essential for 3D printing in the UV LCD technology. It is responsible for projecting images of layers on the underside of the resin tank during the whole printing process. It also masks the UV light so that the resin that is outside the image of a layer is not cured and can be used to print the rest of the model. Therefore, if the LCD screen does not work properly and does not project any image, or it is damaged and has visible cracks, you should replace it before restarting the printing process. Follow the instructions from this manual to replace the LCD screen.
NOTE! The LCD screen has suggested replacement time of about 200 working hours. This period highly depends on the type of resin you use most often. To ensure the highest possible lifespan of the screen, perform regular maintenance according to the maintenance guide.
