Jon from CNCROi.com discusses the process of laser etching raw aluminum, a material that is commonly used in the shop. While most of the aluminum processed in the shop is anodized, Jon demonstrates the difference when working with raw aluminum. Anodized aluminum has an atomic coating that allows for laser etching to bleach and etch the surface, resulting in a clean, off-white finish. In contrast, raw aluminum lacks this coating, but similar results can still be achieved through laser etching.

The main difference between anodized and raw aluminum comes down to the treatment applied to the surface. Anodizing involves a coating process that gives the aluminum a more durable finish, whereas raw aluminum requires direct etching to achieve a similar effect. However, Jon highlights the potential challenges when laser etching raw aluminum, particularly warping due to heat. Unlike stainless steel, which holds heat better, aluminum tends to warp under prolonged laser exposure, causing minor distortions in the material. This slight warping affects the laser’s focus, leading to visual differences, such as a transition from etching to polishing.

To prevent warping in the future, Jon suggests using double-sided tape to secure the raw aluminum to a sturdy surface, which would help maintain a consistent focus during the laser etching process. The speed of etching raw aluminum is also slower compared to anodized aluminum, as the process involves direct etching without the bleaching effect provided by anodizing. Despite this, the outcome is still visually appealing, with a rough texture that adds to the unique look of the etched aluminum.

In terms of production, Jon notes that using anodized aluminum with a clear coat allows for faster results, thanks to the combination of bleaching and etching in one process. For raw aluminum, a different approach is necessary, but CNCROi.com has the capability to handle both types of aluminum efficiently, depending on the client's needs. The flexibility of the laser etching process means that intricate designs can be applied to the surface of aluminum, allowing for custom branding, logos, and other markings.
