abstract = {The second approach is based on the use of a low deposition velocity to achieve sta­ble melting properties combined with a systematic adjustment of the laser beam irradi­ance, which is identified to an important process energy that strongly affects the process temperature and melt-to-solidification behaviour during deposition. To investigate the process-to-part-property relationships, the deposition of wall-like structures using differ­ent laser beam irradiances is analysed by a thermal monitoring system. The wall-like structures are characterized in order to link the results of thermal analysis to distinct microstructural features, which affect the mechanical properties of the structures. Ho­mogeneous microstructure evolutions along the height of the deposited structures are produced. Moreover, it is found that a targeted control of the laser beam irradiance can significantly affect the process temperature and enables the achievement of distinctly different solidification microstructures and mechanical properties.},
