A method for duplex printing a three-dimensional structure by depositing droplets of printing ink at least partially side by side and one above the other, including: depositing droplets of printing ink in a first printing step in order to build up an intermediate first pre-structure, depositing droplets of printing ink in a second printing step in order to build up an intermediate second pre-structure on at least one side of the first pre-structure, rotating the first pre-structure and arranging the first pre-structure on a support structure in a rearrangement step between the first and the second printing step, wherein an extension of the first pre-structure is arranged on a carrier substructure of the support structure and a main body of the first pre-structure is arranged on an deformation-control substructure of the support structure. The teachings further relate to a duplex printed three-dimensional structure as well as a duplex printer.
