The process route for obtaining the processing parameter data through the engraving test first and then using these data for laser engraving was formulated. Through laser engraving experiments on a variety of materials such as wood, bamboo, paper, plastic, leather goods, PCB, acrylic, glass, paint layer, etc., we studied the changes of laser engraving with laser intensity, engraving speed, and black and white contrast. The physical process of laser engraving is analyzed, and the laser engraving of different materials is successfully carried out using the optimized parameters obtained by the experiment. And through the experiment to obtain the appropriate engraving technical parameters, technical parameters include laser intensity, engraving speed, black and white contrast, etc. The experimental results show that different engraving materials have basically different laser intensity, engraving speed, and black and white contrast. The combination of low intensity and slow speed engraving can delay the laser loss. The slower the speed of most materials, the better the effect. Carrying out laser engraving on materials with high ignition points, the effect of low-speed engraving is better. Laser 3D engraving technology is an emerging and promising laser processing technology. This article has reference value for further research on laser 3D engraving.
