Can fiber laser cut acrylic?

LT8020E(2)Fiber laser cutting machine cannot cut non-metallic materials, such as acrylic, cloth, wood, leather and stone, which involves the problem of laser wavelength. The wavelength of the fiber laser cutting machine is 1.06um, and the wavelength range is not within the absorption range of some non-metallic materials. Non-metals are not easy to absorb, or absorb improperly, can not achieve the ideal cutting effect, the cutting effect is not very obvious.

However, the CO2 laser cutting machine can cut non-metallic materials, because the wavelength of the CO2 laser is 10.6um, which is relatively easy to be absorbed by non-metallic materials, and it can cut non-metallic materials with better and more obvious cutting effects. The non-metallic materials that can be cut acrylic, PP and high-quality plexiglass etc.

Under normal circumstances, fiber laser cutting machine can cut metal materials. The output wavelength of fiber laser is 1/10 of the CO2 wavelength. The output beam is of good quality and high power density, which is very conducive to the absorption of metal materials, and the cutting effect is also good. Metal materials that can be cut are: carbon steel, stainless steel, aluminum alloy, galvanized sheet, brass, copper and other metal materials etc.

It is not recommended to use fiber laser cutting machine for long-term cutting of rare metal materials such as aluminum and copper, because these materials are high reflectivity materials (note: high reflectivity has nothing to do with the smoothness of the cutting surface). Mainly because the wavelength of the laser is not in this range, not within the ideal absorption range of the material, the absorption effect is not good, most of the energy is reflected back, it is easy to damage the protective mirror laser), the long-term use effect is not good, and the consumption of consumables will increase.
