This may be a dumb question, but is a solid block 100% of the time stronger than a 'strategically hollow' part. Strategically hollow meaning, the internal structure is design in such a way to support the loading direction?
My thinking is originating from both 3D printing internal supports but also from bio-mimicry designs. Looking at the internal structure of bones, they aren't solid, would they definitely always be stronger if they were solid? Intuitively I would say 'obviously' however could an internal structure is designed in such a way that the surface energy, and load paths create a stronger structure than a single solid block?
If there is a way to design the internal structure, how would you go about designing/analyzing this, if not is there a way to prove that it's not?
