Knowledge of the absorptance during Laser-Based Powder Bed Fusion of metals (PBF-LB/M) is essential in order to investigate the interaction of the laser beam with the powder particles and the substrate of AlSi10Mg. A calorimetric measurement was performed to determine the absorptance of the laser beam. Using additively manufactured samples, the absorptance was investigated as a function of the powder layer, the laser power, and the laser beam diameter. The absorptance varied between 28% and 73% depending on the process parameter and configuration used with the minima at line powers between 1800 W/mm and 2800 W/mm for different beam diameters.
