Abstract: Self-assembly due to capillary forces is a common method for generating two-dimensional mesoscale structures from identical floating particles at the liquid–air interface. Designing building blocks to obtain a desired mesoscopic structure is a scientific challenge. We show herein that it is possible to shape the particles with a low cost three-dimensional printer, for composing specific mesoscopic structures. Our method is based on the creation of capillary multipoles inducing either attractive or repulsive forces. Since capillary interactions can be downscaled, our method opens new paths toward low cost microfabrication.
