Abstract: An apparatus of adjusting and controlling the stacking-up layer manufacturing comprises a target, a powder providing unit, an energy generating unit, and a magnetism unit. The powder providing unit is coupled on a top of the target. The energy generating unit is also coupled on the top of the target. The powder providing unit provides a powder to a surface of the target. The energy generating unit provides the energy beam to selectively heat the powder on the surface of the target to form a melted or sintered powder layer. The magnetism unit provides a magnetic field to control the solidification of the melted or sintered powder layer.

Abstract: The present disclosure provides a device and method for powder distribution and an additive manufacturing method, wherein different size or kind of powders could be chosen to be accommodated within a receptacle. The receptacle can uniformly mix the powder by a rotation movement, pour out the powders by the rotation movement and distribute the powders for forming a layer by a translation movement. In another embodiment, the receptacle further comprises a heating element for preheating the powders. Not only can the present disclosure uniformly mix the powders so as to reduce the thermal deformation and distribute the powder layer compactly, but also can the present disclosure distribute different kinds of powder in different layer so as to increase the diversity in additive manufacturing.

Abstract: A method and an apparatus for inspecting radio frequency identification (RFID) tags which utilize a way of shielding for inspecting whether RFID tags function properly or not. The method of the present invention comprises steps of: reading a plurality of RFID tags in a readable zone; and determining whether there is any malfunctional RFID tag in the plurality of RFID tags. If all the plurality of RFID tags function properly, the method will check a next plurality of RFID tags. If there is at least one unreadable RFID tag, the at least one malfunctional RFID tag will be found by shielding one or the plurality of RFID tags. By means of the disclosure in the present invention, the present method and apparatus are capable of improving the efficiency during inspection and simplifying the design of a readable zone.
