Heat Input Heat input in laser engraving refers to the total amount of thermal energy delivered to the material surface during the engraving process. It is influenced by factors such as laser power, pulse duration, repetition rate, and scanning speed. Proper control of heat input is critical for achieving desired engraving outcomes while avoiding adverse effects such as material overheating, burning, or charring. By optimizing laser parameters and engraving settings, engravers can manage heat input to achieve the desired balance between material removal, engraving depth, and surface quality across a wide range of materials and applications. |
