What materials can be marked by 355nm DPSS UV laser marking machine

The UV laser marking machine is a technology very different from CO2 and Fiber laser technology. Today we are going to explain the main differences between this technologies.


Cold laser engraving


Also knows as the blue laser beam, this technology has the capacity of engraving with a low rate of heat. The light wave or UV light spectrum of this machine is one of the main reasons this technology can engrave over different materials because it doesn’t heat the material surface as the Fiber and the CO2 does. It allows the UV laser mark clear and with high precision over all the plastics and other materials that have an adverse reaction with heat.


Plastics laser marking


There are thousands of different mix of plastics, and all of them can be engraved for UV laser technology, these are some of the most common plastics engraving with our laser engraver machine.


Polyethylene (PE)

Polyvinyl Chloride (PVC)

Polypropylene (PP)

Polystyrene (PS)

Polylactic Acid (PLA)

Polycarbonate (PC)

Acrylic (PMMA)

Acetal (Polyoxymethylene, POM)

Nylon (PA)

ABS (Acrylonitrile Butadiene Styrene)

Other Plastic not mention here.

Metals laser mark


The UV laser it can engrave and mark metals, but not always with the same effect as the fiber laser engraver machine. While a fiber laser can etch over the metal surface with deep effect and with a clear result, the UV laser has problems engraving metals covered with painting, or metals highly reflective like the copper. Check below the list of metals that the UV laser can engrave.







Stainless steel




The UV laser is a full crossover technology, ideal for overall engraving plastics and some common metals. However, one of the significant advantages of this machine comes at the time to engrave some non-metal materials like wood. This machine can make amazing engravings on different wood surfaces. It can’t make deep and fast etching as a CO2 galvanometer laser, but it can produce a light and beautiful marking result.


















Our UV laser machines also can engrave some garments, especially if the garments are rich in synthetic fibers. However, if you want to engrave in specific clothing, we can run a test to check the engraving results before you purchase our machine.


Glass laser mark


The UV laser is one of those technologies that can engrave over glass surfaces without a break or overheat the material. You can create amazing engravings and patterns without splinter glass result. 


Paper and cardboard laser mark


The engraving of cardboard also depends on the material, and the result is different from the usual engraving of the CO2 machines. While the CO2 machines carbonize the surface of the carboards or paper materials, the UV generate a chemical reaction making a marking over the material surface, it is for that reason that we can engrave with white color over cardboard surfaces, and if we want to engrave on black cardboard, we still can get clear contrast, If you have more questions about the engraving of this material, get contact with us.
