Additively manufactured particle-damped (AMPD) beam structures produced by PBF-LB/M are tested in the Einstein-Elevator under microgravity conditions. The first bending mode is evaluated by laser Doppler vibrometry and compared with results from microgravity experiments, using power spectral density inputs resynthesised from those runs and replayed on a shaker. Frequency-domain transmissibility with confidence intervals shows stable mode-specific damping behaviour and supports a validated workflow for future space structures.
