Laser Etched Anodized Aluminum

This instructable will show you how to use a laser cutter to etch anodized aluminum.

Laser etched anodized aluminum.

Laser etching anodized aluminum. Anodized aluminum is an outstanding material used for laser etching. Depending on the color of the anodized aluminum itself a fiber marking laser can efficiently produce darker marks while a co2 marking system can produce bright engraving with contrast. Whether etching images text or logos co2 engraving will leave a contrasting white color on the sheet being processed.

Anodized aluminum tags can be deep rotary engraved in which the engraving cutter cuts through the anodized layer and into the core aluminum. There are some metals you can now engrave with this laser engraver. Able to engrave into dozens of materials including some softer metals including anodized aluminum. Therefore the engraving is a bright silver color in contrast to the color on the surface of the tag.

This type of laser is capable of scribing right through the anodic coating to the bare substrate underneath. Laser machines are an ideal technology for marking and engraving on anodized aluminum and can be used with both co2 and fiber systems. Another advantage of anodized aluminum tags is the high contrast between the surface color and the engraving. This will give the most contrast when engraved.

To laser mark aluminum you should use a fiber laser system. With this process you can mark anodized aluminum on the surface of the anodized layer. Anodized aluminum laser marking when it comes to marking aluminum the most common laser process is laser etching. Anodized aluminum can be produced in a spectrum of colors and shapes and with laser etched markings that.

This allows you to keep the material s high resistance to corrosion and abrasive wear. The anodized coating is heated by laser energy and evaporates requiring little to no cleanup. Another important point when engraving anodized aluminium is that the engraving must be done fast. When engraving onto anodized aluminum it is important that the vector graphic is produced using a rgb colour palette and that the engraving colour is black rgb value 0 0 0.

Laser etching also allows you to mark the bare aluminum before the anodizing process. The laser beam only removes the anodized layer from the aluminum piece resulting in high quality marks. You can thus. There are two types of lasers used for etching or scribing laser engraving metal surfaces.

The color of the mark is highly contrasted between the anodized aluminum and the laser induced mark. Yag for yttrium aluminum garnet is a crystalline solid state laser that emits a wavelength of 1 064 micrometers 1064 nanometers. This includes anodized aluminum. Laser etching anodized aluminum is one of the most common applications of laser engraving machines around the world with its popularity owing to the unique durability and aesthetics of the material and the bright high contrast markings produced by a high quality laser engraving machine.

Some of the features on the orion motor tech 60w co2 laser engraver cutter to consider include. One piece of equipment they have i. Laser marking anodized aluminum is a selective process known as laser etching.
