Benefits of Laser Engraving

In the laser marking process, the surface is heated very quickly to create the colour change, and as the temperature never reaches vaporization point, no material is removed in the process. This, in turn aids bacterial control as scars from machining and/or de-burring are ‘levelled’ into a smoother, grey-coloured surface.

The discolouration created takes place at a depth and therefore, is classified as permanent. Referred to as CW marking or annealing, this process provides possibly the highest quality finish to a medical component. Fiber lasers offer the benefit of non-contact, abrasion-resistant, permanent laser engraving onto most biomedical materials (such as titanium, surgical steel, etc.) making them suitable for a variety of uses be it an implant or a prosthetic. In essence, laser marking systems can offer significant gains over conventional methods, especially within the medical industry.
