Coaxial laser wire directed energy deposition (DED) has become increasingly common in recent years. Laser wire DED provides some advantages over the more common powder blown DED in terms of speed and material usage. However, more work is needed exploring the quality differences between parts manufactured using the two processes. This work covers the development of optimal parameters for the additive manufacture of a high-strength, beta rich titanium alloy using a powder blown DED system and a coaxial laser wire DED system. A design of experiments approach is used to explore the parameter space by varying process parameters such as laser power, scan speed, and material flow rate. The printed parts are evaluated in terms of density, surface roughness, and porosity to compare between the two processes. These results, together with work on microstructure characterization, are presented in this poster.
