Fluid flows deliver square 2D panels together and assemble them into 3D cube. A) Schematic of the fluidic chamber where disconnected square panels are dragged by the flow (blue circular lines) to the center. B) Each panel contains 16 subunits (green spheres) connected together by elastic bonds (black lines). Subunits have functionalities: green—form elastic network; orange—enable bonding between the panels; black—catalyze chemical reactions that drive fluid flows. C) After binding to the central (black) square, the side panels are dragged upward by the flow. D) Side sticky bonds lock the cubic structure.
