I've been planning to order this which just came out last month to try it out, but I haven't had a chance yet. Its supposed to use Graphene nano particles which are light weight and supposed to form very strong structures. Its very expensive though. They do show a wing design in one of the pictures.

strength vs weight in 3d printing
Re: strength vs weight in 3d printing
interesting software jsc. I was involved in CAD system marketing (polite term for sales) in the late '80s.
A story circulated that Boeing had developed a landing gear part entirely with CAD, done the finite element analysis and somehow arrived at the part having only the metal needed to do the job and no more. They went straight to CNC with the design - it couldn't easily be drafted - beyond conventional descriptive geometry. I suspect the point of the story was that had they needed to draw it, more metal would have been required. Of course sometimes more metal is required just to make the thing, but maybe not here.
