The thickness a CO2 laser can cut depends on its power, with higher power lasers cutting through thicker materials. For example, a low-power laser (like 40W) is suitable for thin materials up to 5mm for acrylic or 6mm for softwood, while a high-power laser (such as 300W+) can cut through thicker materials like 10mm to 20mm wood and up to 40mm acrylic. For metal, CO2 lasers are limited to thin sheets, with power levels of 300W cutting less than 1mm of stainless steel, and higher power lasers needed for thicknesses of a few millimeters.

Material type: The properties of the material, such as reflectivity and melting point, significantly impact cutting ability.
Cutting speed: A slower cutting speed can compensate for material thickness or achieve a better edge finish, especially for certain plastics.
Multiple passes: For very thick or difficult-to-cut materials, making multiple passes at a lower power setting can improve cut quality.
Gas assist: The use of gases like nitrogen or oxygen can improve cutting efficiency and quality.
Machine calibration: Correct focal length and beam quality are essential for optimal results.
