Abstract: Elemental powder 3D printing has an important exploration value compared to the traditional prefabricated metal powder 3D printing which the manufacturing process will be greatly shortened and the type of alloy powder will be reduced by rapid online metallurgy. In this paper, elemental powder blender 3D printing technology was developed and a high-throughput printing test platform for metal materials was also fabricated based on this technology. The platform is equipped with 10 channels and can print more than 40 mechanical properties samples for the materials with more than 5 elements at one time. Homogenization is also accomplished during the manufacturing process. The high-throughput platform can offer broad application on composition design and property research of novel materials, such as iron and steel materials, aluminum alloy, titanium alloy, nickel-based superalloy, high-entropy alloy, etc.
