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. Because laser head need to re adjust the focus during engraving.
