Abstract: A method for producing a prefabricated 3D-printed part includes depositing a layer of a particulate aggregate on a production panel by a layer-depositing device; and dispensing a predetermined dose of a binder or a water/binder mixture, comprising water and at least one hydraulic binder, onto a locally predetermined region of the layer of the aggregate by a printhead. At least one reinforcement is arranged by a reinforcement-depositing device, at least in some regions, on and/or in the locally predetermined region on which the predetermined dose of the binder or the water/binder mixture was dispensed during the course of the second method step.

Abstract: A device for producing a three-dimensional laminate for the construction industry from a plurality of layers of particulate material, which layers are arranged one on top of the other on a printing platform, are consolidated in locally predetermined regions, and are bonded to one another to form a three-dimensional laminate. The device includes a printing frame and at least two coating devices for applying the particulate material layer by layer on the printing platform. The at least two coating devices are movably mounted on the printing frame, preferably along a longitudinal guide. A printing head is provided for discharging a binder at the locally predetermined regions, and the printing head is movably mounted on the printing frame, preferably along at least one longitudinal guide. The at least two coating devices and the printing head are in each case movable in relation to one another.

Abstract: A pressure head is for dispensing a water-binder mixture in a controlled manner, the mixture including water and at least one hydraulic binder, in particular a cementitious binder. The pressure head includes at least one supply channel for supplying the water-binder mixture, at least one outlet opening fluidically connected to the at least one supply channel, and at least one valve by which the at least one outlet opening can be opened and closed in a controlled manner. A specified dose of the water-binder mixture can be dispensed through the at least one outlet opening.
