Laser powder bed fusion is the most common metal additive manufacturing technique used today.  This method uses a high-powered laser to locally melt and weld together metal powder alloy that is uniformly spread in a semi compacted bed to produce a 3D printed component.  This method allows designers an unprecedented amount of geometric complexity along with a high degree of net shape capabilities.   is an attractive alloy for metal additive manufacturing as this process produces the high strength to weight ratio inherent to this alloy and avoids the difficulty of machining this high strength reactive metal alloy.  Traditionally, spherical titanium alloy powders produced via inert gas atomization or plasma atomization have been commercialized for use in laser powder bed fusion applications because of the ease of powder spreadability within the metal powder bed.  One drawback of these atomizing techniques is cost as both methods have a lower than desired yield of particles in the correct size range and both methods also use large quantities of argon gas.  Recent collaborative development has shown that lower cost angular Ti-6Al-4V produced via the hydride/de-hydride process can successfully be 3D printed using laser powder bed fusion.  This presentation will review the results gathered by Kymera International and our development partners to date including microstructure and mechanical properties achieved.
