US manufacturer Rosotics has demonstrated the suitability of its HY-80 steel alloy for large-format additive manufacturing. According to the company, the steel, which was specially developed for shipbuilding, will be processed on Rosotics’ M1 metal 3D printing machine in the future.
Until now, the HY-80 alloy has been unsuitable for 3D printing. With the help of Rosotics’ induction melting process, the company now plans to produce the largest additively manufactured metal structures ever made from this steel for the U.S. Navy.
Rosotics says the project underscores the need to open up heavy industry to additive manufacturing. The M1 system, unveiled in 2019, works more efficiently than laser-based systems because it melts metal powder by induction.
