The printer device has at least one printer guide device, a 3D concrete printer device, which is arranged so as to be movable along the printer guide device, and a printer controller. The printer guiding device comprises at least one guideway whose guide path can be adjusted at least in the vertical direction in relation to its spatial position of use. ## Claims ### Claim 1 A printer device for creating a concrete supporting structure of a passenger transport system configured as an escalator or moving walkway in an existing building, the printer device comprising: a printer guide device which can be arranged between two support points of the building provided for supporting the passenger transport system, wherein the printer guide device is designed to be supported on floors of the building at least during a printing process, which floors shall be connected by the passenger transport system, and a 3D concrete printer device which is movably guided along the printer guide device and is configured to spatially arrange workable concrete, the 3D concrete printer device including at least one printer nozzle and at least one movement device for moving the printer nozzle; wherein the printer guide device has at least one guideway, the guide path of which can be adjusted, at least in the vertical direction, with respect to its spatial position of use, wherein the printer guide device has a support structure on which the at least one guideway is arranged or formed and the guideway is adjusted by adjusting the support structure, wherein the support structure comprises at least two serially connected sections, the central longitudinal axes of which can be set at an angle to one another. ### Claim 2 (depends on 1) The printer device of claim 1, wherein the guideway is adjustable relative to the support structure. ### Claim 3 (depends on 1) The printer device of claim 1, wherein a fixable hinge point for adjustment is arranged between two sections of the support structure. ### Claim 4 (depends on 1) The printer device of claim 1, wherein at least one angle segment for adjustment is arranged between two sections of the support structure. ### Claim 5 (depends on 1) The printer device of claim 1, wherein at least parts of the printer guide device are provided as reinforcement or part of the reinforcement of the concrete supporting structure. ### Claim 6 (depends on 5) The printer device of claim 5, wherein the part of the printer guide device remaining in the concrete supporting structure has at least one connection point for receiving further reinforcement material. ### Claim 7 (depends on 1) The printer device of claim 1, wherein the printer guide device has at least at one of its two ends a receiving device for bearing components. ### Claim 8 (depends on 7) The printer device of claim 7, the receiving device being movable relative to the printer guide device and being arranged on the latter so that the bearing components accommodated therein can be aligned with a respective bearing point. ### Claim 9 (depends on 1) The printer device of claim 1, further comprising a printer controller, the printer controller comprising a processor and a memory, the memory storing machine readable instructions that, when executed by the processor, cause the processor to carry out a printing process during the creating of the concrete support structure.
