N1 - Funding Information:
Microstructural analyses were performed by Dr. Mark Turski and Rohima Begum at the Magnesium Elektron Technology Development Center, U.K. Both the directed energy deposition study and the laser powder bed investigations were funded by Magnesium Elektron Powders at the ARL, Penn State University, and at the Laser Zentrum Hannover e.V, respectively.

N2 - Recent investigations using rare earth containing alloy Elektron®MAP+43, which is an atomized alloy powder specifically developed for additive manufacturing (A/M)based on the Elektron®43 composition with a nominal composition of Mg-4Y-3Zr, have shown that it is possible to achieve near-theoretical densities using both laser directed energy deposition and laser powder bed fusion process. Mechanical properties obtained compare favorably with cast and heat treated WE43 alloy. However, to develop a robust process for magnesium-based powders, several aspects need to be considered including identifying suitable particle size distribution, build strategies, metal vaporization and condensation, and interaction of laser with the powder, to name a few. The processing details, microstructure, and mechanical properties for Elektron®MAP+43 process via A/M are presented in this paper.
