An East Valley startup is launching what it describes as the “largest commercial metal 3D printer in the world," targeting customers in the aerospace, naval and defense industries.

Rather than a typical laser used in metal 3D printing, the Halo system developed by Mesa-based Rosotics uses an electromagnetic process the company has developed over years of research and development.

The Halo system consists of three induction-based print heads referred to as "Mjolnir," which are capable of fusing material at a high feed rate. Halo is designed to be a "net shape printer," meaning it incorporates shaping and forming of metal into the overall printing process, eliminating the need for post-processing, according to Christian LaRosa, the company's founder.
