Laser structuring enables the targeted formation of protrusions on metallic surfaces, whose geometry depends on the processing parameters. In this work, we investigated the influence of laser beam speed, number of repetitions, and laser turn-on delay parameter on the dimensions of burrs of three different shapes. Specimens were analyzed using digital and optical microscopy. Burr height decreases with increasing speed and increases with the number of repetitions; at 40 repetitions and 500 mm/s, average dimensions are height 352 μm, length 229 μm, and width 166 μm. The optimal laser turn-on parameter lies in the range of approximately 250 μs, and morphology does not change significantly upon scaling.
