Additive manufacturing method and device based on high-energy beam

The invention provides an additive manufacturing method and device based on a high-energy beam. The manufacturing method comprises the steps that a base body layer is formed, the base body layer is a powder layer or a consolidation layer formed by a base body material, and the base body layer comprises a specific area; and an additional material is added in the specific area such that the additional material and the base body material in the specific area form a new material different from the base body material. By means of the additive manufacturing method and device, high-precision complex objects with various materials distributed at will in the three-dimensional space can be manufactured, and therefore the requirements for different materials and performance of the same object at different parts are met. 本申请提供一种基于高能束的增材制造方法及设备。本申请提供的制造方法包括：形成基体层，基体层为基体材料形成的粉末层或固结层，基体层包括特定区域；在特定区域中添加附加材料，使得附加材料与特定区域中的基体材料形成不同于基体材料的新的材料。使用上述增材制造方法和设备可以制造三维空间上多种材料任意分布的高精度复杂物品，从而适应同一物品在不同部位不同的材料、性能的需求。
