This actually looks pretty good imoI'm pretty sure that is a fairly old Russian (note the Su-47ish auxiliary intakes, and the IRST has been pointed out already) CGI of a much heavier hypothetical fighter. I've had the original on my HDD since late 2009 (!), but can't remember where I got it.

So, it looks like J-31 is land-based while the naval version will be designated as something else. Could it be J-35? Just like J-11 vs J-15...
Does this mean they were able to reduce the weight of conventional structures by 3% with additive composites, or that there is only 3% by weight of composites?Not only this, more article related Jxx:
Propose the innovative design of aircraft structure based on additive manufacturing and the emergency repair design method of carrier aircraft structure damage, establish a variety of innovative additive main bearing structures and functional structures, and the single aircraft consumption (weight) is as high as 1/7 (3%) of composite materials. Established a new mode for rapid trial production of new aircraft, and played a core supporting role in the development of the J-31 and J-XX.
Simply put, composites take up about 21% of the total weight and 1/7 of the composites (3% of the total weight) are treated by additive manufacturing (i.e. 3D printing).Does this mean they were able to reduce the weight of conventional structures by 3% with additive composites, or that there is only 3% by weight of composites?
