Large‐scale, three‐dimensionally ordered arrays of colloid particles (see Figure) have been produced by a new method based on vibratory compacting. The settling dispersions are exposed to controlled oscillatory shear while water is simultaneously removed from the system. This approach can be used for the fast preparation of 3D crystalline assemblies of nanoparticles from their concentrated dispersions.
