Abstract
Producing composite structures includes dispersing a first plurality of objects, a second plurality of objects, and a third plurality of objects in a fluid, the third and second plurality of objects having an average maximum dimension that is smaller than the first plurality of objects The first plurality of objects comprise a first, a second, a third and a forth object, each having mating surface regions The first and second objects' mating surfaces are complimentary and the third and forth objects' mating surfaces are complementary The first and second object aggregate together in response to the dispersing of the second plurality of objects in the fluid due to a depletion attraction between the first and the second object The third and forth object aggregate together in response to dispersing the third plurality of objects in the fluid due to a depletion attraction between the third and the fourth object.
