Reactive Gas Reactive gas is a type of gas introduced into the laser processing chamber during laser engraving or cutting operations to enhance material processing capabilities and achieve specific engraving effects. Common reactive gases used in laser engraving include oxygen, nitrogen, and air, which interact with materials to modify surface properties, improve engraving quality, or facilitate cutting processes.
For example, oxygen-assisted engraving enhances the combustion reaction with organic materials such as wood or acrylic, resulting in darkened or contrasted engraving marks. Nitrogen gas can prevent oxidation and discoloration during metal engraving by creating an inert atmosphere. Reactive gas selection depends on material type, engraving depth, and desired engraving results, allowing operators to optimize engraving parameters for various applications. |
