adding CO2 to your laser cutter
This might sound a little confusing because we have mostly talked about CO2 laser cutters but just to clarify before I begin we're talking about the air assist for the laser cutter rather than the laser cutter tube itself. Replacing your air supply with CO2 can't help with materials that tend to burn and char more. It can even help on films that tend to change color and mar. The only downside of the CO2 is it's definitely more expensive than using the standard air pump.
