摘要： A method of additive manufacture suitable for large and high resolution structures is disclosed. The method may include sequentially advancing each portion of a continuous part in the longitudinal direction from a first zone to a second zone. In the first zone, selected granules of a granular material may be amalgamated. In the second zone, unamalgamated granules of the granular material may be removed. The method may further include advancing a first portion of the continuous part from the second zone to a third zone while (1) a last portion of the continuous part is formed within the first zone and (2) the first portion is maintained in the same position in the lateral and transverse directions that the first portion occupied within the first zone and the second zone.

摘要： A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.

摘要： Gas is introduced into molten metal during an additive metal fabrication process and/or during a metal fusion process. The gas may comprise a process gas that flows through a tubular feed wire. The amount of process gas introduced can be controlled to vary the composition and/or material properties of metal deposits formed from a molten metal. Material properties such as yield strength, hardness, and fracture toughness can be increased or decreased in specific regions to provide material property gradients that closely correspond to expected requirements of components fabricated utilizing additive and/or fusion processes.

摘要： Disclosed are an automatic continuous operation robot for laying large-diameter pipelines and an operating method therefor. The operation robot comprises a platform, a main frame (1), an operation room, a navigation subsystem (1002), a pipe grabbing and conveying subsystem (3), a pipe end face pre-treatment subsystem (4), an on-line measurement subsystem, a pipe supporting subsystem, a welding and welding quality inspection subsystem (5), and a control system. The operating method comprises: first detecting and grabbing a pipe, then performing groove machining on the pipe, fitting the welding end faces of the current pipe and a previous pipe, then putting down the pipe, finely adjusting and fixedly connecting the two pipes, and finally, welding the two pipes. The automatic continuous operation robot for laying large-diameter pipelines has a high degree of automation and high working efficiency, and the laying period is short.
