Study on three dimensional additive manufacturing process using X-ray radiolysis

We present the synthesis of nano/micro-scale metallic and oxidized particles onto various substrates using the X-ray radiolysis with a manufactured flow system. As a typical example, the cupric particles are deposited onto the substrates. Scanning electron microscopy with energy dispersive X-ray analysis, X-ray diffraction, micro-Raman spectroscopy have been demonstrated to investigate and understand the physical and chemical mechanisms to synthesize the particles. These analyses enable us to provide the understanding that the radical ions nucleated by the X-ray irradiation in the solution play a significant role in synthesizing and ripening of particles and clusters. The process using X-ray radiolysis sheds light on the novel three dimensional additive manufacturing process for three dimensional structure formation and additive process.
