The present invention relates to an apparatus for manufacturing a 3D element of an architectural structure. The apparatus includes: a transfer arm unit installed movably along 3D locations; a material supply unit placed at one side of the transfer arm unit to supply construction materials necessary for the manufacture of the architectural element and fillers necessary for the formation of a space in the architectural element; and a control unit controlling the operations of the transfer arm unit and the material supply unit while moving in response to positional information included in data on the shape of the architectural element such that the construction materials and the fillers are stacked on a base plane where the architectural element is to be manufactured. The control unit controls the supply of the construction materials to locations corresponding to the element of the architectural structure and the supply of the fillers to locations corresponding to the space defined by the architectural element.

An embodiment provides a method for printing a three-dimensional structure, including: identifying, using one or more sensors, a geographical three-dimensional location of a print head, wherein the print head is operatively coupled to a platform providing movement over a geographical terrain; correlating the identified geographical location to a location identified within a print file, wherein the print file comprises dimensions and printed structure locations of a three-dimensional structure to be constructed; and constructing the three-dimensional structure until the three-dimensional structure is constructed by iteratively: moving, based upon the correlation, the print head to printed structure locations identified from the print file; when the print head is located at a printed structure location, extruding a structure material from a structure material holding location operatively coupled to the platform; and determining, based upon the print file, whether the three-dimensional structure is constructed.

The present invention relates to a method for casting building material to form a construction element using a computer-controlled apparatus. The method comprises the steps of: moving the material deposition head and selectively depositing material, to fabricate a formwork; pouring building material in contact with at least a portion of the formwork; at least partially curing the building material, thereby forming the construction element; and removing at least a portion of the formwork from the construction element.

A robotised construction system is provided that includes a cartesian robot that can be automatically lifted as the construction is becoming higher, that is provided with a system of robotic supply of the materials and of the electric and electronic installations and that is provided with specific fabrication tools which work some by the contribution of layers of fluid construction materials. In a cement-based usage in which the cement is setting and having been deposited, by projection of these same materials and others by forming and placing construction elements in a determined position.

A photopolymerized prepolymer manufacturing system can create material suitable for 3D printing buildings or building components. The system can include a conveyor, a prepolymerization chamber, and one or more processors. The prepolymerization chamber can have multiple prepolymerization stations arranged in sequence and can convert untreated material into photopolymerized prepolymer material as the conveyor moves the prepolymer past the prepolymerization chamber. The processor(s) can control operations of the conveyor, the prepolymerization chamber, or both, to alter operations in response to a detected system event. Each polymerization station can include a light source, such as an LED array, that irradiates material. Each light source can be in a lid of the prepolymerization station. When operation of one polymerization station is halted, such as for maintenance, then the system can increase the light source intensity of the remaining polymerization stations, slow the conveyor speed, or both.

A mixing-extruding head apparatus for a three-dimensional (3D) printer for building residential houses and other objects, which enables printing of right-angled corners, the apparatus comprising a container for mixing mortar, the container comprising a funnel (1), a two-part helix (6) inside the container for mixing the mortar for building said objects, wherein the two-part helix (6) is installed on a main axis (2) inside the funnel (1) and the helix (6) comprises an inner metal part (6a) and an outer rubber part (6b), and wherein the helix (6) has at least one thread (turn), and an exit nozzle (14). The bottom part of the exit nozzle (14) is on each of its sides equipped with one of four blades (17), which are controlled by a servo-pneumatic system with computer-controlled commands for building the objects, wherein each of the blades is connected to a piston moved by a pneumatic cylinder; wherein all four pneumatic cylinders are connected with four electromagnetic valves, which generate pneumatic signals.

A first aspect of the present invention is a constant force compression construct, comprising: (a) a plurality of compressible layers, each compressible layer comprising a plurality of interconnected flexible struts configured as a regular hexagonal lattice of repeating unit cells, with the layers spaced apart from one another, and with the unit cells of each layer aligned with one another; and (b) a plurality of beams interconnecting each of the compressible layers with each respective adjacent compressible layer to form a three-dimensional lattice having an upper portion, a lower portion, and a compressible region therebetween, with the repeating unit cells contained in the compressible region.

An apparatus for the in-situ formation of a moulding. The apparatus includes a forming head and a forming blade. The forming head has a body having a raw material receiver. The body further has one or more outlets to permit the movement of raw material from the raw material receiver through an outer surface of the body and into an area adjacent to a work surface when the forming head is positioned in proximity to the work surface. The forming blade is secured to the body and imparts a desired profile shape to raw material deposited adjacent to the work surface as the forming head is moved along the work surface.
