The primary characteristics of metal powders are their size distribution and morphology. To guarantee the precision of the metal component production, the metal powders should have consistent characteristics 3. Material properties of the metal powder will affect the surface quality of 3D printing parts. For 3D printing of the end product of the metallic parts, the characteristics of metal powders and the processing of 3D printing, such as sintering, infiltration and surface finishing etc., determine their performances 2.

Powder preparation is one of the key issues for 3D printing. 3D printing offers a possibility to produce complex components without design constraints from the traditional manufacturing routes 1.

It is a technology that produces 3D parts layer by layer from materials, such as polymer and metal. In a word, the method proposed in this paper provides a general way to predict the melting process of electrode induction melting gas atomization (EIGA) dynamically, and it also could be used as a reference for the design and optimization of EIGA.ģD printing, also known as additive manufacturing, offers unrivaled design freedom with the ability to manufacture components from a wide range of materials. The distribution of electromagnetic flux density, eddy current density, temperature, and fluid flow velocity at different time can be determined by utilizing this numerical method. The arbitrary Lagrangian–Eulerian formulation is exploited to model the deformation of Titanium metal during the melting process. In addition, heat radiation and phase change are also considered in this paper. A two-way coupling strategy is used to include the interactions between these fields by incorporating the material properties dependent on temperature and the coupling terms. The melting process simulation, which involves the tight coupling between electromagnetic field, thermal field and fluid flow as well as deformation associated during the melting process, is conducted by adopting the finite element method.

A numerical modeling method is proposed for the melting process of Titanium metals of Titanium alloys powder preparation used for 3D printing.
