Silver has excellent electrical conductivity of up to 6.3×107 S/m, ranking first among all metals, especially suitable for high-frequency, high-precision electronic devices; Its low temperature processing and forming characteristics avoid high temperature damage to the substrate, and have unique advantages in cold spraying and adhesive spraying processes. In the field of additive manufacturing, silver powder shows great potential, especially in high-end areas such as electronics, new energy and medical devices, specific applications include electronic devices and conductive lines, 5G/6G RF devices, biosensors and cold spraying. Additive manufacturing technology can build complex structures, such as porous, mesh, etc., which helps to improve heat dissipation efficiency or functionality, while 3D printing technology can effectively reduce material waste, which is very suitable for cost con
