Metal additive manufacturing encompasses various techniques for creating complex 3D objects layer-by-layer from digital models. Generally speaking, metal AM touts many benefits, including less manufacturing time, lower material waste and, in some cases, stronger material properties than traditional manufacturing processes. The landscape of metal additive manufacturing is constantly evolving for advanced manufacturers in Australia, particularly those serving industries like Defence, Oil and Gas, and Maritime Aerospace and Energy. While techniques like Laser Bed Powder Fusion (LPBF) and Cold Spray have garnered significant attention, Wire Additive Manufacturing (WAM®) offers a compelling alternative, especially when considering large-scale applications. The question often posed to industry specialists is, “How does one know which metal additive manufacturing process is best suited to their workshop needs?” Under ASTM/ISO 52900, there are currently over 18 processes categorised into seven core metal AM techniques; without technology education, the average manufacturer can be forgiven for confusion regarding the process and technique suitable for their specific application. Generally speaking, a majority of Metal AM processes are best applied to smaller componentry or metal parts with a footprint well under…
