British wire-arc additive manufacturing (WAAM) company DEEP Manufacturing and U.S. additive manufacturer Fortius Metals have launched a collaboration to produce multi-material metal cylinders using DEEP's synchronized multi-robot WAAM system. This technology, a form of directed energy deposition (DED), aims to validate whether multi-material metal deposition can achieve the precision, repeatability, and process control required for real-world production. The partnership builds on DEEP's prior work in scaling synchronized multi-robot WAAM, which identified thermal distortion and toolpath generation as major challenges for larger, more complex builds. This project is among the first collaborations announced following DEEP Manufacturing's $10 million investment in a new facility in Houston. The project will begin with test samples and small cylinders, with the main build scheduled for mid-June to early July 2026.
