Abstract

A method of binder jet additive manufacturing (BJAM) is provided. The method includes feeding a supply of powder particles to a powder bed, delivering an organic binder onto the powder bed in select locations of each layer to form a porous green part, and introducing to the binder a secondary component that chemically reacts with the binder to form a solid polymer matrix around the powder particles. The secondary component is introduced either by: (i) infiltration of the secondary component into the porous green part; or (ii) by combining the secondary component with the powder particles prior to feeding the powder particles to the powder bed. A binder system for BJAM is also provided. The binder system includes a reactive pair including an organic binder that is capable of being deposited on a powder bed; and a secondary component that is reactive with the organic binder.
