| This paper introduces the development course, technical characteristics, printing materials and application fields of binder jetting additive manufacturing (BJAM) technology in metal parts printing, analyzes the main factors affecting the quality of metal BJAM parts, and discusses the research focus of metal BJAM technology. The paper generalizes the important development nodes of metal BJAM technology and the maturity of the technology at current stage, summarizes the effects of raw materials, printing and sintering process parameters on the quality of BJAM printed metal parts, and discusses the density, microstructure and mechanical properties of BJAM printed metal parts according to the types of materials. The results show that metal BJAM technology enables the high-efficiency and low-cost production of metal parts, but there are still problems such as low sintering density and serious contraction. It is pointed out that improving the quality of powder laying, developing new types of binder series, as well as simulating and predicting sintering contraction are the key directions of metal BJAM technology development in the future. |
