Whats the difference between 2.5D and 3D laser marking machine?

Whats the difference between 2.5D and 3D laser marking machine?


2D has 2 true axis of X Y axis moving.
2.5D has a 3rd axis but its of very limited utility. It uses the electric Z axis to realize the function of moving up and down
3D has 3 true and relatively equal axis of movement/control in something resembling “volume”.
 

 
The 2.5D laser with 2D galvo head,which only have two mirrors.
 
This is the key technology of 3D laser marking machine.
 
Its working process is: the joint coordination of the Z-direction dynamic axis and the XY-axis is controlled by software. With the difference of the number of processing layers, the Z-direction dynamic axis moves back and forth to focus compensation to ensure the consistency of the light spot during the whole work process.
 
In contrast, when the 3D galvanometer is processing relief, the Z-axis and the XY-axis are fully coordinated, which can achieve nearly microsecond forward and backward movement focus compensation, without being restricted by an external lift table, and higher efficiency and accuracy. The 3D galvanometer is more inclined to industrialized products.
