Metal Marking with a CO2 Laser

CO2 laser machines can directly mark a variety of coated metals such as anodized aluminum or powder coated stainless steel. However, bare metals reflect the wavelength of a CO2 laser, meaning direct marking typically requires a fiber laser source. Fortunately for CO2 laser owners, there's another great option. Bare metals like titanium or nickel plating can be pre-treated with a metal marking compound prior to engraving with a CO2 laser.

What Can You Create?

Using a metal marking spray like CerMark, Enduramark, or LaserBond allows laser owners to perform all kinds of exciting (and profitable) applications such as customizing jewelry and pendants, personalizing stainless steel tumblers, or even serializing metal parts/components.

Imagine the Possibilities

The ability to mark metals with a CO2 laser opens the doors to many new projects. From custom water bottles and personalized phones to identification tags and barcodes, metal items are everywhere. Adding an Epilog Laser machine to your toolset lets you take advantage of these opportunities to work on exciting and lucrative endeavors.

Quality Marks with CO2

You don't need a fiber laser to achieve great quality marks on metal. Pretreating the metal with a special marking agent will allow you to easily mark bare metals with your CO2 laser.

Non-Destructive Marking

Since you're creating a surface mark, rather than etching into the metal itself, you're not compromising its structure or impacting the integrity of the material.

Industrial and Creative Applications

Whether you're applying barcodes to an endless stream of parts or customizing a single flask, metal marking spray and a laser will help you get the job done.
