A review study on metal powder materials and processing parameters in Laser Metaleposition

•The operation window ensures efficient Laser Metal Deposition.•operation window for Laser power is within 0–1500 W (ferrous) and 600–1200 W (non-ferrous).•Uniform material deposition has been achieved within 200–599 mm/min scanning speed.•operation window for powder feed rate is 0–10 g/min (ferrous) and 0–5 g/min (non-ferrous).•0–40% overlap and Gas flow (0–5 ferrous, 5.1–10 non-ferrous) ensure an accurate LMD process.
