Additive Manufacturing Hollow Metal Parts with Liquid Metal

Abstract

Liquid-metal additive manufacturing is a new technology whose limits have not been fully tested. Unique molten-metal droplet printing allows for new metal structures to be made that cannot be built with traditional (powder)-based metal additive manufacturing. This research focuses on the potential to build hollow metal parts with no secondary manufacturing. The research provides a brief background in additive manufacturing and the reason for choosing liquid-metal jet printing. Multiple experiments are performed to test the design limitations of the additive manufacturing printer chosen. This leads to the design of the hollow metal part configurations that are ultimately buckling tested to prove they can support substantial sea pressure. As for the applicability of this research, it focuses on the buoyancy potential of the hollow parts and the potential use they could be to the undersea warfare community.
