Structured surface feature classification on DED-printed parts. Exemplary data and comprehensive influences listing

Directed Energy Deposition is a proven technology for the economic production of medium to large sized metal structures. The process results in a characteristic surface structure composed of the molten layers. It is evident that, the surface structure impairs the strength of the workpiece during static and cyclic loading. Consequently, surface topology evaluation is crucial in the assessment of workpieces manufactured by Directed Energy Deposition. In this work, comprehensive examples of structured feature assessment of real-world workpieces are collected. The examples supplement tabular technical specification of surface features with visual topology appearances.
