The 2D laser galvo model,we also called it 2.5D fiber laser,because laser head still with a 2D laserhead,but this kind machine with motorized lifting pillar.

And the 2D galvo head can be controlled by software,software can control laser head move whenmachine working,so this is why it can acheieve Deep relief work.The technical difference: 3D fiber laser with 3D galvo head which have Z axis mirror,which canmove back and forth; The 2.5D fiber laser with 2D galvo head,which have not the Z axis mirror.t used the Motorizedifting pillar stands for the third mirror to move automatically. Its working process is: in the process of processing, each layer is processed, the motorized liftingpillar moves, adjusts the height of the galvanometer, and then emits laser, so as to ensure that thelaser spot is well focused on each layer, and finally achieve the relief effect.
