Abstract: The experiment was able to produce an application of additive manufacturing to harvest energy. The way to harvest energy uses the Vortex-Induced Vibration (VIV) method. The manufacturing process uses the Additive Manufacturing Fused Deposition Modeling (AM FDM) method. In this experiment, the length of the VIV apparatus was varied. From research it was found that, the longer the apparatus, the smaller the voltage produced. At the same time, the resulting vortex shedding frequency is also getting smaller. In the research, natural frequency measurements were also carried out in the hope that the advantage of AM FDM is that it can produce VIV apparatus with different elastic moduli which is expected to be able to make natural frequencies from the VIV apparatus that are close to the vortex shedding frequency. This frequency equalization process is expected to have resonance from the VIV apparatus which will be able to have a greater frequency.

Keywords: Additive Manufacturing, Energy Harvesting, Vortex-Induced Vibration.
