Functional aspects of 2D, 2.5D, and 3D laser engravers
May 08,2025
The functions a 2D machine can perform are marking, 2D engraving, and deep engraving. The maximum thickness of metal sheets that can be cut is approximately 2 mm. Of course, the focus can be manually adjusted to achieve thicker cuts, but this is a workaround, not a machine function, so we won't discuss it for now.
A 2.5D machine can achieve marking, 2D and 3D engraving, relief, etc. Theoretically, it can cut greater thicknesses (still requires experience, but the premise is that the cutting edge effect is not required). A fixed value can be set according to the height of the workpiece. At the same time, the focal length of a single format lens is fixed, so to a certain extent, thicker cutting can be achieved through software settings.
The functions a 3D machine can perform are marking, 2D and 3D engraving, and embossing. However, due to the influence of the lens, I personally believe that the cutting ability is relatively low and cannot cut thick plates. The most important advantages are engraving, precision, and effect.
A 3D laser engraver is also known as a 3D laser marker, 3D laser marking machine, or 3D fiber laser engraver. It is the most powerful laser engraver on the market, so if you have multiple laser jobs to do, choose a 3D laser machine.
If you only want to engrave on a flat surface, or perform rotary engraving, and do not need 3D relief laser work, choose a 2D laser machine. If you want to engrave 3D relief on a flat surface, choose a 2.5D laser engraver.
