Abstract: A method of making an article of manufacture is provided and includes the steps of spraying a first coating onto a substrate, and depositing a second coating on the first coating by 3-D printing a material disposed in a pattern. The pattern includes ridges disposed at a base surface of a turbine part. Each ridge defined by first and second sidewalls, each sidewall having a first and second end. The ends extend from the base surface, the sidewalls slope toward each other until meeting at second ends of respective first and second sidewalls defining a centerline and a top portion of the ridge. The sidewalls are inclined with substantially equal but opposite slopes with respect to the base surface. The ridges correspond to a back portion of a turbine bucket and are oriented at a first angle with respect to an axis of rotation of the bucket.

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.

Abstract: A method of binder jet printing a metal part includes depositing a layer of a metal powder on a working surface of a binder jet printer and selectively printing a binder solution having a reversible binder into the layer of metal powder in a pattern to generate a printed layer. The pattern is representative of a structure of a layer of the metal part. The method also includes curing the reversible binder in the printed layer to generate a layer of a green body metal part and heating the green body metal part above a first temperature to remove a substantial portion of the reversible binder and generate a brown body metal part. The reversible binder is thermally decomposed to generate oligomers that remain within and strengthen the brown body metal part. The method further includes heating the brown body metal part above a second temperature to remove the oligomers and sinter the metal powder to generate the metal part. The metal part is substantially free of char residue.
