A few days ago Meltio made a public demo of the robotic-based WAAM system and related digital-twin. With that system Meltio can perform any AM task, simulate the printing process, follow it from a digital-twin and fully control the printing process. Meltio now focusing in the LMD (Laser Metal Deposition) version which is controlled by the same software and related infrastructure.
