Laser Marking Titanium Signs

This sample club project was designed with our fiber laser customers in mind. Did you know that creating colors on metals is a great application for our fiber-based laser systems? When subjected to its 1,064 nanometer wavelength, many metals exhibit a color change when processed with an Epilog fiber laser. We’ve found that bare metals, especially titanium, produce the most vibrant colors.

Color marking on bare metals is achieved by varying laser system parameters such as speed, power, frequency, and focus. One of the biggest drivers that impacts color is the focal length – note that we include focus settings in our parameters below. Once you dial in your settings to achieve the color you’re looking for, you can utilize the Color Mapping feature in Epilog’s print driver to automatically run different parameters on different graphics to achieve different colors!

If you’re a fiber laser operator and want to add a little flare to your bare metal marking, try some different laser parameters and see what types of colors you can produce! Below you’ll find the steps we took to achieve bright red, white and blue shades when laser marking titanium.
