    摘要： A method, apparatus, and program for additive manufacturing. The additive manufacturing device includes a positioning mechanism configured to provide independent movement of at least one build unit in at least two dimensions. The build unit may further include a gasflow device for providing a flow zone along a first direction with relation to the build unit. The build unit may further include a powder delivery mechanism and an irradiation beam directing unit. The irradiation bean unit may follow a first irradiation path, wherein the first irradiation path forms at least a first solidification line and at least a second solidification line formed at an angle other than 0° and 180° with respect to the first solidification line. During the formation of the first solidification line, the build unit may be positioned in a first orientation such that the first direction of the flow zone is substantially perpendicular to the first solidification line. During the formation of the second solidification line, the build unit may be positioned in a second orientation such that the flow zone along the first direction is substantially perpendicular to the second solidification line.

    摘要： A magnetic bearing system for controlling magnetic coupling between a mobile carriage and a guideway and a method for controlling the magnetic bearing system. The magnetic bearing system includes at least one engine, which includes at least two poles, at least one permanent magnet and at least one coil. The engine is configured to be magnetically coupled to the guideway through at least one air gap.
