Video: Biggest 3D Manufacturing Machine Builds Jet Fighter Wing Boxes

Very interesting technology. I'm glad they are developing this and increasing the speed that they can produce parts with additive manufacturing. However, it looks like they have a ways to go before it makes sense to use for production. From the video it appears that they have to machine the entire surface of the completed part before it can be used. It seems like using this method for prototyping and modeling makes sense. It should be good for development and even limited production runs. I'm sure we will all be watching this technology evolve with great anticipation.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
