Surface finishing by laser re-melting applied to robotized laser metal deposition

Optics and Lasers in Engineering, 2021
Abstract Low surface quality of as-deposited laser metal deposition (LMD) parts is one of the main drawbacks of this additive manufacturing technology that prevents direct use without the implementation of costly and time consuming post-processes. An in-process surface finishing operation without the need of auxiliary equipment is highly appealing to
