A method of producing curved, folded or reconfigurable structures includes providing a polymer film, exposing the polymer film to at least one of patterned radiation or patterned chemical contact, and conditioning the polymer film subsequent to the exposing. The polymer film includes a polymer that is active to cross-linking of polymer chains in response to the exposing. The exposing is performed such that at least one exposed region of the polymer film develops a gradient in an amount of cross-linking of polymer chains along a cross-sectional direction of the polymer film, and the conditioning of the polymer film removes uncross-linked polymer chains to provide a curved, folded or reconfigurable structure.
