Abstract
A three-dimensional selective repairing system, apparatus and application method thereof are provided. This invention uses a scanning device for scanning a surface of a target that want to be repaired, and it gets a repair data. After using a model comparison module connects to the scanning device for the repair data, and the model comparison module can obtain a repaired data through the operation generated. Then after, an energy generating unit and a powder providing unit are corresponding to repair data to make a powder layer on the surface of the target. The powder providing unit provides a power to a surface of the target. The powder is formed into the powder layer on the surface of the target. The energy generating unit provides an energy beam to selectively heat a particular area of the powder layer. Therefore, the invention provides a magnetic effect to control and sintered powder layer.
