The disadvantage of 2D fiber laser engraving machine is that it can only work on a flat surface. The more function is to use the Rotary System, we can also use it to mark some cylinders, such as cups. Or rings, bracelets, etc. Even in this case, it has many Limited on curved markings. So 3D fiber laser engraving machine and 2.5D laser engraving machine became popular in the market. A large part of it meets many needs of customers. But what is the difference between these three types of machines, the following HANTEN CNC article will show you
From technical part, we called it 2.5D because laser head still with a 2D laser head, but 2.5D with motorized lifting pillar. And galvo head can be controlled by software. software can control laser head move when machine working, so it can achieve 3D engraving. it means 3D laser, Z axis mirror inside laser head to move back and forth; 2.5D, Z axis stands for the third mirror to move automatically.2.5D laser engraving machine can finish all 2D laser work and can make 3D laser engraving on flat plate. 2.5D CANNOT make 3D engraving on curved part. Lifting pillar of 2.5D laser machine must be motorized type.
There are three main applications for 3D laser marking machines. Including curved engraving, Embossing laser engraving and large-working Area engraving.
1) Curved laser engraving
The 3D fiber laser Machine working area is usually below 300*300mm. We can use it to engraving curved and Ball surfaces. Unlike rotary engraving, 3D curved surface engraving has a very high accuracy, automatically adjusts the focal length,Mainly 3-axis dynamic focus technology and layered engraving technology. According to the different points in the working area, the focus is automatically adjusted through the machine software control, so that the 3D fiber laser marking machine can make molds and stamps, copper coins, mold steel and other materials. and works faster. It is the same as the ordinary 2D fiber laser machine
2) Embossing laser engraving
Embossing laser engraving is as popular as Curved laser engraving. We can use it to make many handicrafts, gifts, molds Retro coins and stamp, etc. But the purpose is Mainly for Material do deep engraving
Although the 2D laser machine can do deep engraving, But all the depths are the same, on the same plane. 3D laser engraving can reach different depths, behaving like a three-dimensional pattern, with a three-dimensional effect. Make the pattern more vivid.
3) Large-working area engraving
As we know the maximum working area size of the 2D laser marking machine is 300*300mm. But many customers require a larger working size. Using 3D laser marking machine, usually its working size can reach 600*600mm. As for the larger size, it requires a customized scan head.
