3D printing offers customisation capabilities regarding suspensions for oscillators of vibration energy harvesters. Adjusting printing parameters or geometry allows to influence dynamic properties like resonance frequency or bandwidth of the oscillator. This paper presents simulation results and measurements for a spiral shaped suspension printed with polylactic acid (PLA) and different layer heights. Eigenfrequencies have been simulated and measured and damping ratios have been experimentally determined.
