Laser cutting is a technique that uses a laser to slice materials. Although commonly used in industrial manufacturing applications, it has also begun to be used by schools, small businesses and hobbyists.

Fiber lasers can cut copper, brass, and aluminum better and safer than CO2 because the beam is more easily absorbed rather than reflected. Due to the low power consumption and high electrical efficiency of fiber lasers, the operating cost of fiber lasers is usually only half of the cost that a CO2 system can provide.
