Stainless steel flat plates and square hollow sections (SHS) were built using wire and arc manufacturing (WAAM), laser scanned and their measured geometry analysed. The specimens were subsequently destructively tested in pure compression.

Summary:
3D printing, or additive manufacturing, is gaining in popularity across multiple industries with its ability to manufacture complex geometric forms, in a wide range of materials. Metallic structural elements can be printed, although the existing experimental dataset is very limited.
Stainless steel flat plates and square hollow sections (SHS) were built using wire and arc manufacturing (WAAM), laser scanned and their measured geometry analysed.
The specimens were subsequently destructively tested in pure compression.
Computational methods have been used to characterise the geometric properties and seek their relationship to the buckled shapes of specimens.
