The capillary assembly of stimulus-responsive hydrogel particles with programmed multipolar interactions defined by their prescribed three-dimensional (3D) shapes is demonstrated. Low-energy bending deformations of the particles, driven by surface tension, modifies the interactions between particles, while their temperature-dependent swelling enables switchable assembly.
