Laser cutters are machines that use lasers to cut materials. They use heat to cut through materials, rather than friction, and can be used on all materials except those that reflect light (i.e. copper and aluminum). Developed for mass manufacture, they have only recently started to be used for small scale production and by hobbyists.

Laser cutters are commonly used with wood, especially for plywood or MDF panels with a thickness below 10 mm. Its cut is precise and extremely thin, about 0.1-0.2 mm. Because it uses heat, the laser burns the sides of the wood panels they cut.

Although the laser itself does not require much energy to be generated, these machines consume a lot of energy for cooling.
