Abstract Scope Recently, metal 3D printing technology have been rapidly developed and spread on the large fields of manufacturing industry. From the development of 3D printing, it has to be developed on the raw materials fabricating techniques. Ti is regarded as importance materials for 3D printing because there are many advantages such as high strength to weight ratio, ductility and biocompatibility. However Ti has strong activity with other crucible metals or ceramics as well as gas elements. So, it's difficult to select the crucible for melting the Ti and its alloy. In this study, we suggested that gas atomization with cold crucible melting for spherical shape of Ti powder which could be applied for raw materials of 3D printing. Capability of Ti atomization is higher than 1kgs and close coupled nozzle is used for guiding the melted Ti. The impurities, morphology, microstructure and mechanical properties of Ti powder are analyzed and discussed.
