Additive manufacturing, including the wire arc additive manufacturing (WAAM), is gradually gaining attraction and providing benefits in the aerospace and construction industries. In both industries, large-scale manufacturing capability and quality consistency of manufactured 3D parts are crucial. As part of quality evaluation, test artifacts for the geometric capability assessment are specified in ISO/ASTM52902-2019(E). On the other hand, the test artifact for curved wall is left undefined. This paper proposes a sphere shape wall as a representative of three-dimensional shapes that are supportless and feature large overhangs, for testing the geometric capability. A universally applicable mechanical configuration and deposition strategy for depositing large scale curved walls, is proposed. A quality evaluation process for the sphere deposition was also described and experimentally demonstrated.
