CO2 laser cutting machines utilize a gas laser with a wavelength ideal for cutting non-metallic materials like wood, acrylic, plastic, glass, textiles, and paper. They offer smooth cutting edges and are widely used in industries such as advertising, packaging, textile, and handicrafts. CO2 lasers can also engrave on various materials, adding to their versatility. However, they have lower efficiency when cutting metals compared to fiber lasers and require more maintenance due to their complex optical systems.
