Abstract: An additive manufacturing apparatus includes a process chamber having a length, a support extending along the length of the process chamber, a printing assembly, a vision system configured to image a dispensed binder pattern, and an electronic control unit communicatively coupled to the printing assembly, the first actuator, and the vision system. The electronic control unit is configured to cause the printing assembly to traverse the build zone in a forward or reverse direction while dispensing binder according to a programmed deposition pattern, receive image data from the vision system of the dispensed binder pattern resulting from the programmed deposition pattern, analyze the image data to determine whether there is an anomaly in the dispensed binder pattern, and in response to determining the anomaly in the dispensed binder pattern, adjust the programmed deposition pattern for a subsequent traversal of the printing assembly over the build zone to address the anomaly.

Abstract: According to various embodiments, an additive manufacturing apparatus comprises a process chamber surrounding a print head, a recoat head, and a linear motion stage to which the print head and the recoat head are coupled. The print head and recoat head operate within the process chamber to build a three-dimensional object by depositing a build material and a binder material. The additive manufacturing apparatus further comprises a condenser system fluidly coupled to the process chamber to receive a gas stream with a first vapor content from the process chamber and provide the gas stream with a second vapor content to the process chamber. The second vapor content is less than the first vapor content. Additionally, the additive manufacturing apparatus comprises a blower fluidly coupled to the process chamber and the condenser to flow the gas stream through a closed loop comprising the blower, the process chamber, and the condenser.

Abstract: Systems and methods for machining openings of a component are provided. In one exemplary aspect, a laser system includes features for machining an opening into a component, such as a cooling hole for a CMC component of a gas turbine engine. The component can be oriented in a first position and lasered while oriented in the first position to form a portion of the opening. The component is then oriented to a second position and lasered while oriented in the second position to form another portion of the opening. The component is alternated between the first and second positions until the predetermined geometry of the opening is formed. The component is oriented in the first and second positions such that the laser beam can machine the component without clipping areas that are not desired to be machined.
