Binder jet printing is an additive manufacturing process in which a powder feedstock is spread out, a binder agent dispensed in a pattern according to the part design, and more powder spread over the existing layer. This sequence repeats until the height of the part is reached. The printed part is delicate and must be heated to burn out the binder. The part is then sintered to achieve a higher density. The powder feedstock characteristics are critical to the entire process, as particle size and shape affect powder spread and density of green part. The density of the green part and how the particles behave in heat treatment dictate the density, strength, and hardness of the final product. This study compares various materials and particle behavior to printer settings on an ExOne Lab binder jet printer to develop standard printer settings and conclude ideal powder feedstock characteristics.
