Abstract:Based on the rapid development of additive manufacturing, this paper summarizes several preparation techniques of high-performance spherical metal powder for 3D printing technology, including Vacuum Induced Gas Atomization (VIGA), Electrode Induced Gas Atomization (EIGA), Plasma Atomization (PA), Plasma Spheroidization (PS) and Plasma Rotating Electrode Process (PREP). The microstructural and mechanical properties of the final components using the gas atomized and plasma rotating electrode powders are compared.The aim of this work is to discuss the development tendency of gas atomization technologies, provide guidance for the selection of preparation methods and materials, and thus promote the industrialization of additive manufacturing.
