Investment casting has been used in the aerospace military equipment

civil aviation and commercial aerospace area during the industrial development. In this paper

its research and development status in superalloy

titanium alloy

aluminum alloy and magnesium alloy were discussed in detail

and the research results of BIAM in recent years were mainly introduced. Different process characteristics among the investment technology and additive manufacturing

semi-solid forming

injection molding and other new process technologies were analyzed

meanwhile the development direction and research hotspots in the future were expected.
