Binder jetting (BJ) is a 3D printing technology in which objects are manufactured from ceramics, metals, polymers, and composites. Binder jetting process incorporates various types of technologies, such as printing, deposition of powder, complex combination of the binder with powder, and post-processing of sintered part. BJ has high productivity with the utilization of a wide variety of powders. In BJ, the binder is combined with powder of materials that bond together to create an object in a layer-wise fashion that is generally modeled on CAD. In order to obtain desired product accuracy, the main challenges are balancing proper process parameters with manufacturing time, such as characteristics of powders (distribution of particle size, packing density and flowability of powders, green strength), characteristic of binders, etc. This paper gives a brief review of technologies, materials, defects and challenges of the binder jetting additive manufacturing process and their future trends. <br>
