    Abstract: In some embodiments, a photoreactive 3D printing system and methods comprise providing a system with a resin tub comprising a membrane, wherein the membrane rests on a physical tension element such that increasing downward force on the resin tub induces increasing tension on the membrane. The system also comprises a plurality of sensors comprising a resin bulk temperature sensor, and a print recipe comprising information for each layer in a 3D printed part to be built on the print platform. In some embodiments, a resin bulk temperature is measured, and the information in the print recipe, including information related to the downward force on the resin tub, is updated during a printing run based on the resin bulk temperature measurement. In some embodiments, the print recipe can be updated during a printing run based on input from at least two sensors of the plurality of sensors.

  • Patent number: 11072932
    Abstract: Systems and methods of shotcrete construction are contemplated whereby guide rails are placed in proximity and forward to a shotcrete receiving surface, with any guide rails disposed directly in front of the shotcrete receiving surface being configured to be offset from the receiving surface allowing shotcrete to be sprayed behind the offset guide rails. Following application of shotcrete, a screed configured to engage with and traverse along at least two of the guide rails may be used to rod the shotcrete via a protruding region of the screed extending beyond the guide rails, thereby removing excess shotcrete and imparting to the shotcrete surface a contour at least partially defined by the configuration of the guide rails and the configuration of the protruding region of the screed. Complex, precise, and even exotic architectural shotcrete installations may be created in this fashion by providing a suitable set of guide rails and screed.

  • Patent number: 8591778
    Abstract: A method and apparatus for constructing railways for a rubber-wheeled AGT system are provided. The method includes forming guideways, along which guide rollers of a light rail vehicle moves when the light rail vehicle runs along railways and forming, using a pressing unit of a finisher, the railways applied with concrete such that the railways have a same trace as the guideways by moving a finisher along the guideways. The apparatus includes a vehicle that is provided with rollers to run along guideways installed on vertical walls of a road bed and a pressing unit that is disposed under the vehicle to make lateral and longitudinal traces of railways correspond to lateral and longitudinal traces of the guideways by pressing and forming a top surface of railway concrete during the running along the guideways.

  • Patent number: 8061037
    Abstract: A method for casting monitored pilings and a pour diverter used in connection with the method is provided. The method includes positioning a plurality of pile strands in a form, and then connecting a suspension assembly having at least one sensor to at least one of the pile strands so that the at least one sensor is located in a piling core area. A pour diverter, having a generally V-shaped configuration, is positioned over the suspension assembly. Concrete is poured into the form over the pour diverter so that a flow of the concrete into the form is split and flows down on either side of the suspension assembly until the at least one sensor is covered. The pour diverter is then removed to finish the casting. Preferably, provisions are provided on the pour diverter for holding or covering an antenna assembly during the pour, prior to it being placed into the concrete forming the piling.
