摘要： The present disclosure relates to a system for additively manufacturing a structure for transporting carbon dioxide. The system makes use of a nozzle component having a housing. The housing has a first nozzle for receiving a powder capable of capturing carbon dioxide, and channeling the powder through the nozzle component. The housing also has a second nozzle configured to receive a polymer component and to channel the polymer through the housing without intermixing of the polymer and the powder. A print head is in communication with the housing and configured to receive both the powder and the polymer, and to co-extrude the powder and the polymer so that the polymer forms a shell that encases the powder as the powder and polymer are co-extruded.

摘要： A three-dimensional, additive manufacturing system is disclosed. The first and second printer modules form sequences of first patterned single-layer objects and second patterned single-layer objects on the first and second carrier substrates, respectively. The patterned single-layer objects are assembled into a three-dimensional object on the assembly plate of the assembly station. A controller controls the sequences and patterns of the patterned single-layer objects formed at the printer modules, and a sequence of assembly of the first patterned single-layer objects and the second patterned single-layer objects into the three-dimensional object on the assembly plate. The first transfer module transfers the first patterned single-layer objects from the first carrier substrate to the assembly apparatus in a first transfer zone and the second transfer module transfers the second patterned single-layer objects from the second carrier substrate to the assembly apparatus in a second transfer zone. The first and second printer modules are configured to deposit first and second materials under first and second deposition conditions, respectively. The first and second materials are different and/or the first and second deposition conditions are different.

摘要： A 4-dimensional printing system and method for printing reinforced concrete may allow reinforced concrete elements to be printed freeform and/or fully automated without the need for formwork, molding, or labor. The printing system may include software and hardware systems. The software system may process 3D models of the reinforced concrete element desired into multiple layers. The software system may utilize the individual layer to control operation of the hardware system to print the desired reinforced concrete element layer-by-layer. The hardware system may provide a concrete nozzle, a reinforcement material nozzle, as well as dispensing mechanisms for printing the materials at the desired locations and/or at desired times for the individual layer being printed. The hardware system may also include motion control mechanism(s) that allow the position of the nozzles to be moved sideward, up and down, and towards or away relative to the element being printed.

摘要： A method operates a three-dimensional (3D) metal object manufacturing system to compensate for displacement errors that occur during object formation. In the method, image data of a metal object being formed by the 3D metal object manufacturing system is generated prior to completion of the metal object and compared to original 3D object design data of the object to identify one or more displacement errors. For the displacement errors outside a predetermined difference range, the method modifies machine-ready instructions for forming metal object layers not yet formed to compensate for the identified displacement errors and operates the 3D metal object manufacturing system using the modified machine-ready instructions.
