So it is a bit click baity, sure. But how many people really think about anisotropic plies? (cool word, anisotropic, by the way)

Folks who have done 3D printing figure out pretty quickly that the orientation of the print can have a large effect on the various structural properties of the thing printed. I basically spent the first couple of months printing various test objects in different orientations to get a better understanding of this.

For that reason, the paper gives a reasonable way to approach the question of "how can I make this stronger?".
