Abstract
A method of binder jet printing a part includes depositing a layer of a powder on a working surface and selectively printing a binder solution comprising a binder into the layer of powder in a first pattern to generate a printed layer. The pattern is representative of a structure of a layer of the part. The method also includes selectively printing a channel support agent solution comprising a channel support agent into the layer of powder to generate a green body. The channel support agent is selectively printed in a second pattern representative of an internal channel of the part. The method further includes heating the green body part above a first temperature to remove the binder and generate a brown body part and heating the brown body part above a second temperature to sinter the powder to generate the part having the internal channel generated from removal of the channel support agent.
