Laser marking machine have very fast development nowadays, we can see 2D laser marking machine have very wide application in so many fields. But the disadvantage of 2D laser is it can only work on the flat surface. With the help of rotary device, we can use it mark some cylinder, such as cup. Even in this case, it have many limitation on curved surface marking. So 3D fiber laser engraving machine rise in the market.

1. 3D means Dynamic focusing, compare with ordinary 2D laser machine, 3D laser marking machine use different galvo head. Ordinary 2D scanning head only have two mirrors, but 3D scanning head have three mirrors. The third mirrors can move forward and backward. This is the key technology of 3D laser marking machine.

2. Except scanning head, control card and control software is the brain of laser markers. One good control software will make complex operation become very easy. Most company will development the software together with scanning head.

3. We know the max working size of 2D laser marking machine is 300*300mm now. But many people need do large working size. With 3D laser marking machine, usually its working size can reach 400*400mm and 600*600mm. As for bigger size, it need customized scanning head.

4. Although 3D laser marking machine have many special application, its price also is higher now. Most customers can’t accept it. With the help of development and price decreasing, it may become same popular with ordinary laser in the near future.

5. In terms of work, 2D marking is mainly suitable for flat marking and some deep engraving. 2D can not do curve marking and engraving. 3D marking is suitable for embossing, deep engraving and large format marking, especially for marking or deep engraving with uneven, curved and spherical surfaces.3D marking area with 600*600mm and 400*400mm. ( Recommend power ≥50W ) 

6. Control system is different. 2D use EzCAD, 3D use 3D control card. ( Feeltek or SINO 3D automatic dynamic focusing head can be choosed. Feeltek use Feeltek 3D control card. SINO use Marking Mate control board )

7. 3D fiber laser marking machine the dynamic focusing head include the F-theta lens itself. 2D fiber laser marking machine the Laser scanner and F-theta lens is separated.
