Method for producing a prefabricated 3d-printed part

Method for producing a prefabricated 3D-printed part, preferably a concrete prefabricated component, for the construction industry, comprising the following method steps:

• in a first method step at least one layer of at least one particulate aggregate is deposited on a production pallet by means of at least one layer depositing device,
• in a second method step a predetermined dose of at least one binder or at least one water-binder mixture, comprising water and at least one hydraulic binder, in particular a cement-based binder, is delivered at at least one locally predetermined region of the at least one layer of the at least one aggregate by means of at least one printhead,
• wherein
• in a third method step at least one reinforcement is arranged, by means of at least one reinforcement depositing device, at least in regions on and/or in at least the at least one locally predetermined region, at which the predetermined dose of the at least one binder or the at least one water-binder mixture was delivered in the course of the second method step, wherein in the course of the third method step the reinforcement is sunk, preferably by pressing, shaking and/or vibration, at least in regions into the locally predetermined region of the at least one layer of the at least one particulate aggregate, in which the predetermined dose of the at least one binder or the at least one water-binder mixture was delivered.
