I'm quite certain the strength of a 3D printed part (for example a curved shell like a nose cone, a wing tip or something like that) with carbon strands embedded in the filament never can compete with the same shell created the regular way with layers of weaves criss crossing over a the bulged surface because of the way the model is sliced and printed layer by layer.

Some of the properties may be achieved if one were to have the build plate swivel under the extruder. This together with a slicer that slices the thickness of the surface should be able to produce a part with each layer consisting of fibres criss crossing each other...
