Additive manufacturing technology has been developed in Xi’an Jiaotong University for almost 20 years. Up to now,it is still attracting the attentions of the researchers or manufacturers all over the world. Some innovative processes and frontier application research are all being conducted here to catch up with the new development of this technology. In the paper,newly developed processes,such as ultraviolet-light emitting diode (UV-LED) stereolithography,ceramic stereolithography,and direct metal forming,were described. Some results of the frontier application researches,such as indirect fabrication of ceramic casting mould,wind-tunnel-testing models,photonic crystals and metamaterials,were also briefly reviewed.
