Non-Beam Additive Manufacturing of Metals

Abstract

Additive manufacturing of titanium alloys has significant potential as a disruptive technology. While conventional additive manufacturing routes use electron or laser beams to selectively melt materials into the final component geometry, alternative non-beam-based methods show the strongest potential for reducing cost and improving throughput of additive manufacturing technologies. This research focuses on a Capstone senior design program to evaluate two non-beam-based additive manufacturing methods: binder jetting and metal extrusion. The results of sintering and thermohydrogen treatments on a titanium alloy (Ti-6Al-4V) are assessed in terms of the mechanical and microstructural characterization.
