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.
Materials Needed
- Titanium Plates
- Loctite Super Glue
- Scrap Wood
- Epilog Laser System
We used a Fusion M2 32 Dual Source with 30-watt Fiber:
Square: Fiber // Raster // Speed 10% // Power 100% // 80f // +.08 out of focus
Number Outline: Fiber // Raster // Speed 70% // Power 30% // 1f // in focus
Number: Fiber // Raster // Speed 9% // Power 100% // 40f // +.08 out of focus
Step 1: Prepare Artwork
Download the graphics above and import it into your graphic software. Make adjustments as necessary.
Step 2: Send to the Laser
Send the job to the laser with the correct parameters for your machine wattage.
Step 3: Assemble
Glue the back of the plates to front of the wood.
Where can you sell custom laser marked titanium signs?
- As housewarming gifts
- For interior/exterior directional signage
