Gas Assist Gas assist in laser engraving involves the use of compressed gas, such as air or nitrogen, to aid in the engraving process. The gas is directed onto the material surface being engraved, helping to remove debris, cool the material, and improve engraving quality. Gas assist also reduces the risk of flare-ups and discoloration during engraving, particularly when working with materials prone to melting or charring. By controlling the flow and pressure of the gas, engravers can optimize engraving performance and achieve consistent results across different materials and thicknesses. |
