- Abstract
- In aeronautics, selective laser melting (SLM) brings a new field of geometry optimization allowing a reduction of the weight and an improvement of the efficiency of aircraft pieces like heat exchangers. Geometry optimization leads to complexe desgin with many thin elements whose roughness could be an issue. In this context, this work shows how laser parameters and scan strategy have an impact on the roughness of thin elements like thin walls. AlSi10Mg 3D-Printed thin walls (600 μm-thick) were thus fabricated with a set of varying parameters such as the laser power, the scan speed and scan strategy. Roughness (Ra, Rz and Rmax) has been recorded by white light interferometry. Melted Pool analyses were also conducted on each samples in order to understand the effect of each parameter.
