Underburn Underburn, in laser engraving, refers to a phenomenon where the laser beam penetrates the material surface insufficiently, resulting in incomplete or shallow engraving depths. Underburn commonly occurs when engraving settings such as laser power, speed, or focus are not properly calibrated for the material being processed. Factors such as material type, density, and composition influence the extent of underburn experienced during engraving operations. To mitigate underburn, operators must optimize engraving parameters to ensure adequate energy absorption and penetration into the material while avoiding excessive heat buildup or surface damage. Proper material preparation, engraving technique, and system calibration are essential for achieving consistent engraving results and minimizing underburn effects in laser engraving applications. |
