I want to cut very delicate patterns into paper and cardboard, but I don’t want the edges to be blackened by burning. Is this possible with a laser cutter? Maybe with multiple passes?

    Would it work if there’s a constant flow of intert gas like argon to displace the oxygen where the laser cuts? Same process is used to prevent oxidization during welding.

      While this does prevent the oxidation of the molten weld metal it doesn’t prevent discoloration from the vapor deposition on and around the weld, or slight oxidation from the hot metal as it exits the shielding gas cloud. Paper is less prone to this kind of oxidation but even welding on a vacuum can still produce some discoloration from the vaporized material
