This is equipment that can print patterns using a laser. Searching for "DK-8-KZ" will bring up review sites, so please look up the specifications yourself. I may not be able to provide accurate information as it has been a while since I last used it. It's a type of engraving machine where the base moves, similar to a 3D printer. It's powered by an AC adapter and receives print instructions via a PC connection. You can download the control app from the NEJE official website. The process involves loading an image file, setting the laser intensity, and then executing the print.
