Research status and development trend of 3D printing binders

Three-dimensional 3D printing binders are important in the modern industry. Several types of binders and printing materials are used. Thus, printing binder requirements differ considerably depending on the printing methods utilized. In this study, the characteristics and research status of biomimetic materials and polymer binders used in Selective Laser Sintering-based printing (SLS), Spray molding technology (such as, solid inkjet printing [3DP] and Metal binder jet printing (MBJ), and extruded bio-printing technology (EBP) are reviewed.
