Laser Effects

Laser Ablation

This is the most common method of laser marking.  The laser removes one layer of material ,exposing another layer.  In most cases the result is a high contrast, crisp mark.

Laser Engraving

In this method, some material is removed, giving the mark some depth, and as a result could also leave some raised edges.  The laser interacts strongly with the material.  With this process, in some cases, the engraving is later backfilled or used in a molding process.

Direct Laser Marking

Direct Laser Marking changes the color of the materials, thus creating a contrast.  Sometimes this happens naturally.  Sometimes additives are added, especially in plastics, to enhance the mark.









Laser Annealing

In this method, no material is removed.  The material changes color.  This is a very gentle, fine tuned interaction of the laser with the material. 


Generally, laser annealed parts are used in medical and other related industries where oxidation needs to be avoided due to agressive environments.

Virtually all materials can be laser engraved.  By choosing the right laser and laser settings, a large variety of  different effects can be achieved. 

All laser marks are permanent.
