That part packing using a physics simulation is genius, very clever. I did some nesting of fabric long ago, never even thought about doing it using a physics simulation. Lovely stuff. Of course in nesting fabric there are a lot of constraints due to weave orientation (especially in that application, sails for boats), presumably this 3D printed stuff gives you at least a bit more freedom though I would not expect it to be equally strong in all directions. Even so, the parts they made are already challenging that because of the connectors protruding from all angles so presumably the re-orientation due to packing will not make the parts much less strong.

SLS parts aren't substantially weaker in the Z direction like your typical FDM parts are.
