Duplex printing of three-dimensional structures with adjustable deformation control

Abstract

A method for printing a three-dimensional structure by depositing droplets of printing ink at least partially side by side and one above the other, including steps of: 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, where the support structure includes a carrier substructure and a deformation-control substructure, and where the deformation-control substructure comprises a pressure chamber. The present teachings further relate to a corresponding duplex printed three-dimensional structure and a duplex printer.
