Abstract

The current landscape of manufacturing is evolving because of technology like additive manufacturing (AM). The mobility and compactness of AM are what make it desirable for many industry sectors. The U.S. Navy has shown interest in deploying AM on ships as it could alleviate their dependency on off-route docking to recharge supplies. However, the U.S. Navy's aspiration is currently hindered due to harsh ship-borne environments that degrade AM part quality.

This thesis focuses on vertical base vibration effects on AM part quality. An introduction is first given in Chapter 1 to familiarize the reader with the U.S. Navy's predicament. The harsh environmental factors of marine military environments are discussed in Chapter 2, centered on vibrationestablished, Chapter 3 narrows in on the experimental approach to 1) understand how vertical base vibration affects AM part quality and 2) provide an example for how to mitigate the vibration effects with a passive isolation scheme. The overall approach of Chapter 3 is a suggested path for inspecting other AM printers and applying mitigation strategies for deployment in harsh environments. Finally, the thesis concludes with a discussion on the main results and future work to continue or extend this research.
