Fiber lasers are best for marking many types of aluminum, brass, copper, stainless steel and more as well as engineered plastics such as ABS and polycarbonates. The laser must also be run at a low-speed, high-power configuration to allow the marking agent to adequately bond with the metal.įor bare metals, fiber lasers represent the engraving method of choice.
More time is required for marking metals with a CO2 laser, for instance, because of the need for coating with a metal marking agent. Fast and affordable, CO2 lasers can also mark other types of materials such as woods, acrylics, natural stone, and more.ĭifferent types of lasers marking machines for metal react differently with metals, there are some considerations to be made. The heat from the CO2 laser bonds the marking agent to the bare metal, resulting in a permanent mark. When marking bare metal with a CO2 laser, a special spray is used to treat the metal prior to engraving. Fiber Lasers can be tailored to have a higher beam quality than many other Lasers of comparable average output power. UV laser and Co2 laser can also mark some metals.įiber lasers are designed with the ability to mark barcodes, company logos on stainless steel, aluminium, gold, silver, titanium, etc.
The fiber laser can mark all metals and some types of plastic.
