A fiber laser marking machine: This is good for all kinds of metal materials and ABS.

A UV laser marking machine: This is good for all kinds of materials. UV laser marking machine for ABS plastic marking will get a much better result than a fiber laser marking machine, this is because of the UV laser wave length is 355nm thermal reaction is very small on the marking materials， it get a very good result than fiber laser.  However, fiber laser marking machine with a life about 110000 hours，compare with UV laser marking machine is 20000 hours is a big difference. Whats more UV laser is much more expensive than a fiber laser marking machine. Last but not least, we need to buy a correct machine for our products marking.
