摘要： The present application relates to a method of producing an article by additive manufacturing including the steps of predicting regions of stress in the article, identifying an optimal build orientation for the article and dispensing a first powder and/or a second powder to form the article. The first and second powders are of the same type of powder and have been recycled to different extents and the orientation of the build is optimised so that reduced quantities of the powder which has not been recycled or which has been recycled to a lesser extent is dispensed during the build.

摘要： Closed-loop metal powder management methods for additive manufacturing. Virgin metal powder is provided in a closed powder container comprising at least one sensor, tracker, or optical device. The metal powder is transferred to an additive manufacturing system, a portion of a metal powder layer is consolidated, and excess metal powder is transferred from the additive manufacturing system to the powder container, a second powder container, or an internal powder container. Virgin metal powder or a second metal powder are added to the excess metal powder, a quality of the mixed powder is validated, the process is repeated at least once, and powder physical transfer data associated with at least one of the steps is collected and stored in a data repository. Powder material parameters may be measured and assessed, and may be also be stored in the data repository.

摘要： This invention relates to a method for feeding magnetic objects in a stream which are singulated each from the next in a supply path where there is provided a series of electromagnets which provides a sequence of magnetic fields along the supply path to direct the magnetic objects by the series of electromagnets in a required direction toward a required location. The method can be used for carrying out an operation on a workpiece by interaction of the objects as individual tools with the workpiece including sorting, shaping, material removal, physical modification, chemical modification, addition of material cutting, polishing, abrading peening and addition of energy. A lubricant/purge material is supplied to the workpiece to arrive at different times relative to the tools.

摘要： The present disclosure provides three-dimensional (3D) printing systems, apparatuses, software, and methods for the production of at least one requested 3D object. The 3D printer includes a material conveyance system, filtering system, and/or an unpacking station. The material conveyance system may transport pre-transformed material (e.g., powder) against gravity. The 3D printing described herein facilitated reducing interruptions of (e.g., providing non interrupted) (ii) material recycling, and/or (i) material dispensing through a component of the 3D printer such as a layer dispenser. The material conveyance system may operate above ambient pressure, e.g., while performing a suction operation. The present disclosure provides three-dimensional (3D) printing processes, apparatuses, software, and systems for controlling and/or treating gas and gas borne debris in an atmosphere of a 3D printer.
