Engraving anodized aluminum is the most effective and reliable method when using a diode laser. When the laser passes over it, the laser removes the colored layer and exposes the bright aluminum underneath. Laser cutting is gaining acceptance in many fields as a way of cutting metals, plastics, and other composite materials. The advantages obtained by applying the laser in cutting include increased accuracy of the cuts, short time for preparation, minimal loss of material, and the potential to create. Laser engraving of metals has become increasingly accessible even to makers on a budget. Controlling the experimental vari-ables, butt joints with higher.
