摘要： A method for connecting or joining a first substrate and a second substrate across an interface between the first substrate and the second substrate. The method includes disposing a fastener precursor in the bore and sintering the fastener precursor in the bore. The fastener precursor densifies and shrinks in at least one dimension to mechanically interlock with a contour in the bore and form a mechanical fastener in the bore, and the mechanical fastener forms an interlock between the first substrate and the second substrate.

摘要： An acoustic core has a plurality of cell walls formed of an additive-manufacturing material and a resonant space defined by the plurality of cell walls. At least some of the resonant cells have sound-attenuating protuberances formed of an excess amount of the additive-manufacturing material having been intentionally introduced to the cell walls and protruding into the resonant space with a semi-random orientation and/or size.

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 and apparatus are provided for producing a multicomponent feedstock being delivered through a print head of a 3D printer. Multiple component lengths are produced from separate feedstocks and are aligned to form the multicomponent feedstock which is fed into the print head for extrusion. The method includes providing at least two sources of feedstock of different material, feeding a distal end of a first feedstock along a feed path, cutting the first feedstock at a pre-determined length to provide a length of first feedstock having a proximal end. The method includes feeding a distal end of a second feedstock along the feed path and aligning the distal end of the second feedstock with the proximal end of the length of the first feedstock. The second feedstock is cut at a pre-determined length to provide a length of the second feedstock serially aligned with the length of first feedstock, to form a length of multicomponent feedstock. The length of multicomponent feedstock is fed into the print head.
