A test article formed may include a body having a forward face and a rearward face horizontally opposite the forward face. A first surface extending between the forward face and the rearward face of the body may include a plurality of protrusions for removable coupling of the body to a build plate. A second surface on the body may extend between the forward face and the rearward face of the body, and may include a plurality of angled flat surface portions. Each of the plurality of angled flat surface portions may have a distinct angle with respect to a horizontal plane of the body. An angular difference between each adjacent angled flat surface portion in the plurality of angled flat surface portions is substantially uniform.
