制造巨头格力肯航天（GKN Aerospace）已与美国空军研究实验室（AFRL）达成合作，投入840万美元启动“钛工业化与近净成形增材制造技术进步”（TITAN-AM）计划。
该计划旨在将丝材激光金属沉积（LMD-w）技术应用于实际的航空航天生产，重点关注下一代飞机所需的大型结构部件。项目由五个互相关联的重点支柱组成：
1. 规模化：扩大LMD-w工艺以处理超大型钛合金结构件。
2. 数据库建设：建立全面的材料性能数据库以保证结构完整性。
3. 仿真工具：开发先进的计算工具以优化设计和生产结果。
4. 无损检测：完善专门适用于增材制造零件的无损检测技术。
5. 实证验证：通过实际航空航天结构组件的手动演示进行全方位验证。
格力肯航天机身首席技术官大卫·邦德表示：“TITAN-AM代表了航空航天结构增材制造的重要一步。通过将我们的制造专业知识与AFRL的愿景相结合，我们的目标是加速LMD-w技术的成熟度。”该公司在3D打印大型航空结构件方面拥有超过二十年的经验，其在德克萨斯州沃斯堡的全球技术中心将成为该项目的研发中心。
Engineering and manufacturing company GKN Aerospace has partnered with the U.S. Air Force Research Laboratory (AFRL), committing $8.4 million to a new initiative called Titanium Industrialization and Technology Advancement for Near-net Additive Manufacturing (TITAN-AM).
The program is designed to utilize wire-based laser metal deposition (LMD-w) for real-world aerospace production, with a particular focus on building the large structural components that next-generation aircraft demand.
Five Pillars Driving the Program
TITAN-AM is structured around five interconnected priorities. The first is scaling LMD-w processes to handle oversized titanium structural parts. The second involves building comprehensive material performance databases to guarantee structural integrity.
Third, the team will develop advanced computational tools to sharpen both design and production outcomes. Fourth, non-destructive inspection techniques specifically suited to additively manufactured parts will be refined. Finally, the program will validate everything through hands-on demonstrations using real aerospace structural components.
All program activity will be carried out at GKN Aerospace’s Global Technology Centre in Fort Worth, Texas, a facility already well established as a nerve center for manufacturing partnerships with U.S. defense and aerospace stakeholders.

“TITAN-AM represents a significant step forward in additive manufacturing for aerospace structures. By combining our deep manufacturing expertise with AFRL’s vision, we aim to accelerate the readiness of LMD-w technology and demonstrate its value on operational titanium structural components,” said David Bond, CTO Airframes for GKN Aerospace.
From Lab to Flight: A Proven Track Record
GKN Aerospace brings over two decades of additive manufacturing experience to the program and holds an established position in large-scale 3D printed aerospace structures. According to the company, adopting LMD-w at scale is expected to lower material waste, compress production timelines, and open up greater geometric freedom for intricate components.
The company already manufactures the fan case mount ring for the American aerospace company Pratt & Whitney GTF (Geared Turbofan) engine family through additive processes at sites in both Sweden and the United States, with those parts currently in service on the Airbus A220 and Embraer E195-E2.
The Strategic Case for Taking Wire Printing to Production
Aerospace manufacturers no longer treat large-format titanium printing as a future ambition, they are actively qualifying and scaling it. Titanium defines the structural backbone of modern aircraft precisely because of its strength-to-weight ratio and corrosion resistance, yet conventional machining wastes enormous quantities of the material. Wire-based laser deposition solves that problem at the source: by building near-net-shape components layer by layer, LMD-w slashes t
