I do quite a bit of 3d printing of functional parts and am trying to understand how this would fundamentally differ from printing at 100% infill? What type of part requirements are causing failures when something is just solid? Just curious what problem space this is targeting?

Z layer weakness is the main reason that 3d printed parts are brittle and much weaker than injected molded ones.

This is meant to knit together the part in the Z axis
