In Strasbourg, AMFREE developed a wire laser additive manufacturing (WLAM) technology to produce Europe’s largest metal parts (up to 5m). The pilot unit deposits iron-, nickel-based, and hardfacing materials, cutting lead times (e.g., a stainless steel mold in 3 weeks vs. 12 months).
Collaborating with ArianeGroup, three aluminum alloys for rocket parts were tested. Alloy 2319 achieved 400+ MPa, while 5183—though harder to deposit—proved cost-effective. Challenges (deformation, back reflections) led to a multi-wire nozzle, doubling deposit rates and improving control.
This innovation is now embedded in AMFREE One, an industrial, easy-to-use WLAM machine with real-time monitoring, launched last year. The first cell entered production 6 months ago.
The complete AMFREE solution (machine, software, services) targets aerospace, energy, defense, and railways, enabling high-value parts, repairs, and cladding with unmatched scalability.
