Parameter Influence on Surfi-Sculpt Processing Efficiency

The three-dimensional laser surface modification manufacturing technique, Surfi-Sculpt®, is thought to be driven by a melt pool instability that is dependent on a quasi steady-state temperature field. The melt pool instability can be controlled through a greater understanding of the heat input and selection of optimised laser processing parameters. This in turn enables the optimum production of a range of feature shapes, so that this new manufacturing technique can be applied in applications requiring increased surface area of the substrate or functional surface textures.
