The disclosure relates to a printer device as well as a method for building a printer guide structure of a passenger transport system configured as an escalator or moving walkway in an existing building. The printer device comprises at least one printer guide device, a 3D concrete printer device, which is arranged such that it can be moved along the printer guide device, and a printer controller.

A 3D printing system for 3D printing of concrete buildings or other concrete structures. A set of cable support masts are temporarily installed at corners of a two-dimensional footprint area of any given level of a multi-level building to enable 3D printing of wall sections or other structural components of that given level of the building using a cable-guided concrete dispensing nozzle suspended from said cable support masts by a set of movable, motor-driven positioning cables. The building is built in stage-wise fashion, level-by-level, with the set of support masts being moved up level-by-level as the levels of the building are completed. The construction of the building is not dependent on a set of ground-level towers distributed around the ground-level footprint of the building, thus notably reducing equipment requirements for the 3D printed construction of tall, multi-storey buildings.

A system for manufacturing a structure includes a supporting frame assembly moveable in a vertical direction of the structure. Further, the system includes an additive printing assembly secured to the supporting frame assembly. The additive printing assembly includes at least one printer head configured to dispense a first cementitious material. The system also includes a reinforcement dispensing assembly supported by the supporting frame assembly. Thus, the reinforcement dispensing assembly is configured to automatically and continuously dispense a plurality of reinforcing members as the structure is printed and built up via the at least one printer head and as the supporting frame assembly moves in the vertical direction.

A system and method is provided to construct a structure using three dimensional printing of extrudable building material to a wall surface of a structure. According to one embodiment, a printing assembly is moveably disposed above the surface, and extrudable building material is applied from a nozzle onto the surface. One or more profilometers measure at periodic intervals along a geometric cross-section of a bead of extrudable building material. One or more controllers compare the measured cross-section to a predetermined, target cross section and one or more controllers periodically change, for example, the rate of application and/or the viscosity of the extrudable building material applied along the longitudinal axis. The nozzle direction can change, and the profilometers can be rotated about the nozzle along different longitudinal axes, or directions, depending on the wall locations being formed.

A gantry-based 3D printer contains two vertical columns, connected with each other by a horizontal fixed beam, designed with the possibility of moving along rail guides. The rails are mounted on the printer base. A cross beam is installed on the vertical columns designed with the possibility of moving in the vertical direction; and the carriage with the print head attached to it and the possibility of longitudinal movement is mounted on the cross beam. The rails are equipped with an alignment system, which contains washers, nuts and screws, the latter of which are embedded in the base of the printer. The vertical columns and a cross beam are equipped with V-shaped rails with an additional leveling system, and the vertical columns and a cross beam are moved by roller carriages with the help of a drive and helical rack.

An additive manufacturing system includes a gantry architecture with three orthogonally oriented beams along the X-, Y-, and Z-axes. The first beam (X-axis) and second beam (Z-axis) are configured to translate with respect to each other, while the second beam and third beam (Y-axis) are further configured to both translate and rotate relative to one another. A computer-controlled printing system is mounted to the first beam and includes at least one nozzle capable of depositing construction material suitable for building habitation structures. This configuration supports large-scale, spatially dynamic and artificially intelligent 3D printing.

Embodiments of a constructions system for constructing a structure atop a foundation are disclosed. In an embodiment, the construction system includes a rail assembly. The rail assembly is configured to be mounted to the foundation. In addition, the construction system includes a gantry movably disposed on the rail assembly. The gantry is configured to translate along a first axis relative to the rail assembly. Further, the construction system includes a printing assembly movably disposed on the gantry. The printing assembly is configured to translate along a second axis relative to the gantry. The second axis is orthogonal to the first axis. The printing assembly is configured to deposit vertically stacked layers of an extrudable building material onto a top surface of the foundation to construct a structure.

A device for additive manufacturing of a component includes a material dispensing unit for depositing a building material and an actuator assembly which is designed to move the material dispensing unit over a work surface in order to deposit the building material layer by layer in predetermined print paths. The device has at least one first guide leg which is designed to shape a first surface of the one or more layers of building material deposited by the material dispensing unit. The at least one first guide leg is displaceable and driven by a first actuator, in at least one translational degree of freedom (x, y, z) relative to the material dispensing unit. The at least one first guide leg is driven by a second actuator so as to be pivotable relative to the material dispensing unit in at least one rotational degree of freedom (dx, dy, dz).
