Rosotics targets Additive Manufacturing of HY-class alloy steel structures for naval environment
October 25, 2023
Metal Additive Manufacturing machine maker Rosotics, based in Mesa, Arizona, USA, announced during New York Tech Week that it has completed initial studies for the large-scale Additive Manufacturing of high yield strength HY-class alloy steel structures, designed for use in challenging naval and marine environments.
Building on the company’s experience in high-performance aerospace materials, established through the introduction of its M1 Printer, the company aims to collaborate with additional partners in the naval sector to enter operational deployment by 2025.
The low-alloy steel, known as HY-80, is used for manufacturing submarine hulls and has until now remained outside the scope of Additive Manufacturing, explains Rosotics. Using its M1 AM machine, the company aims to produce large metal additively manufactured structures and subject them to open-water deep submergence testing for analysis by the US Navy.
Rosotics uses an Additive Manufacturing process it refers to as Rapid Induction Live Interpass (RILI). Said to be more energy-efficient than conventional laser-based systems, the process uses induction as a means to liquefy metal feedstock.
