Metallic powders are widely used as the feedstock material for many additive manufacturing processes. Titanium alloys in particular are used in aerospace construction as an attractive alternative construction material due to the superior properties they exhibit. This paper highlights the process used to produce titanium alloy powder for additive manufacturing, and the characterisation methods used to qualify the atomised powder against specifications contained in applicable test standards. The electrode composition was compared to commercially available wrought samples, and cylindrical rod structures 13 mm in diameter and 90 mm in length were laser printed.
