航空航天：如何制造XXL铝制零件？AMFREE 线上活动讲解 WLAM 技术
Veranstaltungshinweis: Luft- und Raumfahrt: Wie lassen sich XXL-Aluminiumteile herstellen?
德国机床制造商协会 VDW 发布活动通知，AMFREE 的 Clément Knittel 与 Félix Boisselier 将于 2026 年 6 月 26 日 11:15–12:00 以线上形式介绍用于制造大型金属件的 WLAM（Wire Laser Additive Manufacturing，丝材激光增材制造）技术。总部位于斯特拉斯堡的 AMFREE 开发 WLAM 技术，可生产欧洲最大的金属零件，尺寸最大达 5m；试点设备可沉积铁基、镍基及耐磨堆焊材料，将交付周期从 12 个月缩短至 3 周（如不锈钢模具）。AMFREE 与 ArianeGroup 合作测试了三种用于火箭零件的铝合金，其中 2319 合金达到 400+ MPa，5183 合金虽更难沉积但更具成本效益。针对变形与背反射等挑战，公司开发了多丝喷嘴，使沉积速率翻倍并改善控制。该技术已集成到去年发布的工业级 WLAM 设备 AMFREE One 中，具备实时监控功能，首个单元已于 6 个月前投产。完整方案（设备、软件、服务）面向航空航天、能源、国防和铁路领域，支持高价值零件制造、修复与熔覆。

Neues aus der AM-Szene mit Clément Knittel und Félix Boisselier von AMFREE über die WLAM-Technologie (Wire Laser Additive Manufacturing) zur Herstellung großer Metallteile.
Datum: Fr. 26.06.26
Uhrzeit: 11:15 – 12:00 Uhr
Ort: Digital
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.
Clément Knittel and Félix Boisselier
- Félix Boisselier is a co-founder of AMFREE and leads the company’s technical activities. A mechanical engineer by training, he has spent his entire career in metal additive manufacturing, with a strong focus on Laser DED technologies. After several years working with powder-based systems, he contributed to the development of AMFREE’s innovative wire-based process head, which is now at the core of the company’s commercial offering. Passionate about technology and engineering, Félix combines deep technical expertise with a practical approach to industrial innovation.
- Clément Knittel is the Sales Director of AMFREE, a Strasbourg-based startup he joined at its creation in 2023. AMFREE stands out for its innovative technology in the field of metal additive manufacturing using Laser Wire DED, a rapidly expanding sector. With a degree in Materials Engineering, Clément began his career in the steel industry before transitioning to the energy sector. This diverse experience has equipped him with a robust and varied expertise, which he now applies to the development of AMFREE.
