The ionic liquid beam additive manufacturing technique combines the characteristics of electrochemical deposition and additive manufacturing. It has received extensive attention due to its characteristics of metal manufacturing at normal temperature and liquid beam processing. The evolution history of ionic liquid beam additive manufacturing technique is reviewed briefly. In view of its poor localization and low manufacturing efficiency, the ionic liquid beam additive manufacturing technique based on jet electrodeposition is proposed. Finally, some research focuses and development prospects which are the ionic liquid beam additive manufacturing for special-shaped parts, large structural parts, micro components and multi-functional composite parts are also pointed out.
