This is a pretty amazing airplane which has been 3D Printed, and actually can take flight. It's not a passenger plane, instead a very large toy. The plane was created by a team at the University of Virginia's Engineering school, and has a wing span of six and a half feet. Still very impressive I would say:

That's big... !
Very interesting and good looking plane. I wonder how it compares in weight and strength with a Balsa & Plywood model?
Only from my experience printing large quadcotpers (500mm prop to prop) if using ABS, its very forgiving in crashes, PLA not so much. The advantage is tho when building these things, PLA does not warp as much, its very rigid, so with large ABS parts after cooling down they can warp out of shape, especially long quad arms - looks like they had some serious printers to print that all in though, and several of themQuote:

Very Nice prints! Is that a KK2 holder you have there?
Yeah I print alot of them out, I have about 5 KK.20 boards (i saw them in stock and went nuts...) so I print the cases to protect them all, they dont take long to print, probably 45mins for the whole case.Quote:

Weight Reduction! This is only a frame, it would still have to have a covering applied to all surfaces to be able to fly. I do not know how thick the walls are but I am thinking it is very heavy for a model this size. I think this was more an exercise in construction than an attempt at a flying model? Most RC Modelers try to make their planes as light as possible.
I think as John said, all weight reduction, but without seeing it fly it's hard not to believe those holes wouldnt affect it aerodynamically (in a negative sense) Alot of air pockets, alot of backwash) I would love to know the infill % on this plane, if they are building at 100% infill for rigidity, that explains the holes as 100 percent infil makes the plastic pretty heavy.Quote:
