Moreover, it allows aircraft engineers tap design tricks that are known to be more efficient and effective but are also expensive and wasteful to create in practice--like the elliptical wings on SULSA. So perhaps it's no surprise that elsewhere in the UK a team of Airbus engineers is working on printing an entire aircraft wing--that is, a real jetliner aircraft wing, the kind that would carry people--with the ultimate goal of printing out most of the important components of an entire passenger aircraft.
