Surface modification of binder-jet additive manufactured Inconel 625 via electrospark deposition

Advancements in additive manufacturing have facilitated its adoption in the aerospace industry, where a lower production volume for high-valued components is required. However, the poor surface quality of additively manufactured parts is detrimental to component lifespan and requires additional post-processing steps. Here, we address surface roughness and near-surface porosities in binder-jet additively manufactured Inconel 625 parts using an …
