Large components are inherently complex and expensive to cast using traditional methodologies. Using wire arc additive manufacturing, large format components can frequently be produced more economically and within a shorter time frame. These components frequently exhibit less porosity, and can have qualities that are desirable relative to casting. It is not uncommon for austenitic stainless steels to be utilized in large industrial castings. For this reason, a 316L stainless steel structure is producing using this technology, and its strength, porosity, and microstructure is characterized for industrial use.
