Provided are a random multi-color three-dimensional physical anti-counterfeit marker, manufacturing device and manufacturing method. The manufacturing method comprises: designing, via a computer, a pattern of a marker grain and a laser operation trajectory; placing a thin sheet member on a processing pillow block, and producing a marker grain having a three-dimensional hollowed-out marker by irradiating the sheet member with a focused high-energy laser pulse light; and randomly distributing the marker grain in a transparent adhesive or a surface of an object to be marked, so as to form a random multi-color three-dimensional physical anti-counterfeit marker. The method reduces raw material costs and manufacturing processing steps, thus improving manufacturing efficiency, and decreasing the amount of waste materials and liquids to better protect the environment. |
