Aluminum profiles are best material for quick modular architectural structures build outs. In most cases there are two popular surface coating for aluminum metal. One is anodization and other is powder coating. Both fabrication methods can be laser engraved. This sample engraved by LaserCutZ shows usage of both MOPA fiber laser and UV laser. Those lasers produce different results and should be used depending on client requirements. On left you can see grey laser engraving, this was done with UV laser. Under UV laser, powder coat pigment changed its color to gray. This engraving method does not penetrate coating so there is minimal relief but unlike paint or inking this is absolutely permanent marking that cannot be removed. Such gray engraving can achieve artistic representation and be less intrusive in terms of visual appearance. On other hand MOPA fiber laser will go deeper into material and cause higher color change making artwork to be almost white. This produce big contrast and easy to read signage. Artwork also have more 3D texture as laser recessed deeper into material. In case of fiber laser we can engrave even deeper and penetrate top layers of metal to expose material color or do micro polishing to imitate silver appearance. Regardless of laser technology used, both methods will produce durable marking that will last forever and provide exceptional visual appearance.
