Additive Manufacturing: Controllable Fabrication for Integrated Micro and Macro Structures

Additive manufacturing technology has been developed at Xi’an Jiaotong University for almost twenty years. Innovative process development and frontier application for additive manufacturing technologies have been conducted here since then. In the present paper, the newly developed processes, such as low-cost UV-LED and high-efficiency stereolithography, ceramic stereolithography, and direct metal forming, will be briefly reviewed. Some results of the frontier application research, such as indirect fabrication of ceramic casting molds, wind-tunnel-testing models, and photonic crystals and metamaterials, will be also discussed. On the basis of all these R&D activities, an academic viewpoint on additive manufacturing technologies with “controllable fabrication for integrated micro and macro structures” was proposed and used to guide the further research.
