Right. This should be helpful for all 3D printing. Finite element analysis on infill patterns looks like it helps.

This pattern looks like it's designed for an isotropic material. Sintered metal printers ought to produce solid metal. Extrusion printers, though, tend to have weaker inter-layer bonds than bonds within the layer. So this may not work as well in PLA. Might need a pattern that compensates for the weaker inter-layer bonds.
