Impact score: 66
Oak Ridge National Laboratory (ORNL) collaborated with Boeing to produce a nearly 2-ton stamping forming die (SFD) in eight weeks using multi-material WAAM technology. The tooling supports NASA's Hi-Rate Composite Aircraft Manufacturing project. It features a low-carbon steel structure with a stainless steel working surface, integrally formed internal curved cooling channels, and was optimized through 32 simulation iterations to limit distortion to within a few millimeters. The wire-based process, alongside powder bed processes, serves as a reference within the metal additive manufacturing landscape.

ORNL与波音3D打印近2吨飞机模具
美国橡树岭国家实验室与波音合作,用多材料WAAM技术历时八周打印出近2吨重冲压成形模具(SFD),服务NASA Hi-Rate复合材料飞机制造项目。低碳钢结构+不锈钢工作面,内部弯曲冷却通道一体化成型,32次模拟迭代将变形控制在几毫米内。线材工艺,与粉末床工艺同属金属增材路线参照。
