CO2 lasers are used in the majority of stand-alone engraving devices. They are inconvenient to use and expensive to buy and operate. CO2 laser heads can also cause dangerous accidents during use i.e. shock from the high-voltage current.
On the contrary, blue laser heads are small, relatively cheap, and convenient to use. They can be used as a replacement for CO2 lasers. Blue laser heads are perfect for working with wood and wood-based materials, such as plywood, balsa, MDF, cardboard, and paper. They also allow their users to cut and engrave leather, fabrics, and plastics dark materials engrave especially well. With a blue laser head, users can also mark steel and titanium, cut rubber, and even engrave glass.
