How much does it cost to run a CO2 laser
Plasma, on the other side, can efficiently cut any metal up to 80mm thick and 3 inches in diameter. When cutting thicker materials, plasma can begin cutting much faster than laser.
Fiber lasers can also cut through reflective materials, provided they have enough power. With enough power, they can cut through almost any metal. Their cutting power will limit their ability to cut through thicker metals.
