Binder Jetting

Video credit: ExOne: Digital Part Materialization / Industrial 3D Printing

This method employs a binding agent jetted onto a material powder bed. After each layer, a new powder coat is spread with a roller. This technique yields precise results and is used to manufacture parts from a variety of materials, including plastics, metals, sand, and plaster. However, these parts are often fragile and require post-processing treatment.
