The metallic glass has broad application prospects in many important engineering fields because of its unique mechanical and physical properties. Faced with the situation that it is difficult to manufacture the bulk metallic glass with complicated structure because of the drawbacks in forming size, structural complexity and material variety, the project proposes an additive manufacturing method to manufacture metallic glass by acoustic droplet ejection. The effect of focused ultrasonic wave on the formation mechanism of metallic glass gel droplet and the interactional principle between metallic glass gel accumulation layers will be researched. In order to improve the mechanical performance of metallic glass lattice structure, homogenization method will be employed to predict the performance of lattice structure model and optimize the lattice structure parameters. For clarifying the strengthen mechanism of metallic glass part manufactured by acoustic droplet ejection additive manufacturing technology with complicated structure, the bonding mechanism of metallic glass powder during the sintering process and the influence of sintering parameters such as temperature on degree of crystallization and density will be explored. For promoting the development of metal glass manufacturing field and providing a scientific basis for metallic glass acoustic droplet ejection additive manufacturing, the controlling shape and performance additive manufacturing of metallic glass with complex structure will be realized and the metallic glass acoustic droplet ejection integrated evaluation system of forming material, manufacturing technology and mechanical properties will be established.
