Abstract: A 3D printing system can include an extruding system, a curing system, a positioning system, and a feedback system. The extruding system can include a feed pipe coupled to a printing material source and a nozzle having a longitudinal axis along which printing material is extruded. The nozzle can extrude printing material at a printing angle between the longitudinal axis and the top surface of a layer of printing material being printed. The curing system can include light or other curing components configured to cure the printed material after extrusion. The positioning system can include a platform that supports the extruding system and a platform rotating subsystem that rotates the platform during the printing process to adjust the printing angle. The feedback system can include a processor and sensors to detect the location of the nozzle with respect to the 3D printed object or other objects in the printing area during the printing process.

Abstract: 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.

Abstract: A system for obtaining a photopolymerized prepolymer for use as a component of a material suitable for manufacturing buildings or building components by 3D printing processes. The system contains a flexible closed loop conveyor stretched between a precursor loading station and a prepolymerization material receiver from which the product is unloaded to a construction 3D printing machine. The conveyor carries a plurality of flexible trays capable of looping around the pulleys of the dosed loop conveyor. The trays are shallow troughs that have open tops and carry dosed portions of the precursor, which is photopolymerized on its way from the loading station to the unloading station by sequentially passing under light sources of two photopolymerization stations. When the trays pass through the unloading position, they are turned upside-down and allow the precured material to fall into a receiver.
