Abstract: Methods and apparatus to identify additively manufactured parts are disclosed. An example apparatus includes a body, formed of layers layered substantially parallel to a base layer, composed of a first material having a first density, a first indicium embedded internally in the body as a void, and a second indicium on an external surface of the body, the second indicium aligning with the first indicium.

Abstract: Methods and apparatus to identify additively manufactured parts are disclosed. An example method of manufacturing includes layering a first set of layers of a first material via an additive manufacturing technique, the first material having a first density and layering a second set of layers of the first material via the additive manufacturing technique, the second set of layers to form a void embedded internally in the part, the void forming an indicium.

Abstract: A mold body for use in a mold includes a mold cavity, a chill cavity, a fill channel, and a chill material having a thermal conductivity that is greater than the thermal conductivity of the mold body disposed within the chill cavity. The chill cavity is formed adjacent the mold cavity and is separated from the mold cavity by a chill wall. The fill channel is in communication with the chill cavity and with an exterior surface of the mold body.

Abstract: Example composite valve plugs and related methods are disclosed. Example apparatus disclosed herein include a valve plug tip, a valve plug body, and an additively deposited material. The valve plug tip includes a head portion and a tail portion extending from the head portion. The valve plug body includes a cavity extending from a first end of the valve plug body toward a second end of the valve plug body. The cavity matably receives the tail portion of the valve plug tip. The additively deposited material is bonded to the valve plug body to retain the tail portion of the valve plug tip in the valve plug body.
