Laser engraving is the biggest revolution in the traditional method of engraving. The laser engraving difference is that the machine used for 3D laser engraving will not direct contact with the surface to be etched.
A laser is just a tool that will have direct contact with the surface to be etched or engraved. The use of laser for engraving has made the process really simple, which was previously regarded as a complex process.

The laser beam is so powerful that it needs to be controlled while it is used in industrial purposes, but it can cut the surface to be etched in fact. These laser engraving machines were introduced in earlier 90's and all the working of this machine controlled by the computer hardware and the software installed in that.
All kinds of automation systems actually have well-designed hardware and software to control all machine operations.
Now the machines are really developed that image or design that need to be etched can be saved to a computer that controls the operation and the software will only engrave or mark them to the design surface.
These laser machines were actually designed to engrave so many different types' materials like plastic, glass, wood etc. Due to the success of laser engraving machine companies began to apply laser in so many fields such as laser marking systems, automation systems, hot stamping, etc.
