Abrasive finishing of additively manufactured components

Journal article, 2026

Additive manufacturing (AM) enables the production of complex, near-net-shape components, but as-built components exhibit high roughness and defects that compromise performance. Abrasive finishing processes are essential to achieve the required surface integrity, dimensional accuracy, and functional properties of components. This review examines state-of-the-art abrasive post-processing for AM, including grinding, abrasive fine-finishing, and mass finishing approaches. Interactions within AM process chains, effects on surface topography and mechanical properties, and industrial case studies are discussed. Current challenges and future research needs are identified to guide the integration of abrasive finishing into efficient AM process chains.
