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.
Quick parts production of structural parts that’s actually to be used in art installation. This is low density light weigh aluminum cut with fiber laser. Unlike water jet aluminum cutting, fiber laser does not get into direct physical contact with material so there is no shaking, vibration or any other defects on parts edge that you would normally see when metal is cut with water jet. Fiber laser aluminum cutting is best option to process aluminum sheet metal.

Advantages of fiver laser over any other laser or metal cutting procedures that it can deliver superior precision during cutting. For instance most CO2 high power metal lasers barely can achieve 0.4mm kerf (laser diameter) where our custom build fine cut fiber laser can do kerf size of 0.01mm. Part you see on the video is less than 1” in diameter (it’s actually 20mm) smallest hole on the part is 1mm. If such hole to be cut by CO2 or Waterjet it would not be possible at all. So video shows clear benefits of fiber laser for cutting of small parts that require high precision.
