To provide an additive manufacturing apparatus of a shaped article capable of suppressing evaporation of metal and scattering of spatters. An additive manufacturing apparatus of the shaped article includes a temporary heating device heating metal powder arranged in layers at a temperature equal to or lower than a fusing point of the metal powder to allow the metal powder to be diffusion bonded and a main heating device heating the metal powder at a temperature equal to or higher than the fusing point of the metal powder by irradiating the diffusion-bonded metal powder with a light beam to thereby form a shaped article. The temporary heating device heats a range wider than an irradiation range with the light beam by the main heating device.

The present invention belongs to the technical field of high throughput preparation and hot working of materials, and in particular to a high throughput micro-synthesis method of multi-component materials based on the temperature gradient field controlled by microwave energy. This invention, characterized by flexible material selection, quick temperature rising and high-efficient heating, uses microwave heating both to achieve quick preparation of small block combinatorial materials under the same temperature field in one time and to realize micro-synthesis under the different temperature gradient fields in one time including high-throughput sintering-melting and heat treatment of materials. This invention successfully overcomes drawbacks of current material preparation, such as unitary combination of components, low-efficient external heating, unique control temperature, huge material consumption and high cost during material preparation and heat treatment.
