An imaging device for an additive manufacturing system is provided. The additive manufacturing system includes a material. The imaging device includes a high resolution imaging bar including at least one detector array, and an imaging element positioned between the at least one detector array and the material. The high resolution imaging bar is displaced from the material along a first direction and extends along a second direction. The high resolution imaging bar is configured to generate an image of a build layer within the material.

A method and apparatus for a robot self-locating on a movement surface. The method may comprise moving a first robot across the movement surface and relative to a workpiece, in which the movement surface faces the workpiece. The method may also form sensor data using a first number of sensors on the first robot as the first robot moves across the movement surface, in which the sensor data represents identifying characteristics of a portion of the movement surface. The method may also determine a location of the first robot on the movement surface using the sensor data. The method may further determine a location of a functional component of the first robot relative to the workpiece using the location of the first robot on the movement surface.

Systems and methods of computer aided manufacturing are disclosed. A computer aided manufacturing device includes a tool operable to perform a manufacturing operation within a working area. A scanner obtains scan data of the working area. A processor is configured to configure scan-specific controls, operate the scanner to obtain scan data of the working area, generate a digital model based on the scan data, configure setup parameters for the at least one tool, generate a first tool path for the at least one tool to perform a first manufacturing operation within the working area based on the digital model and the setup parameters, operate the computer aided manufacturing system to perform the first manufacturing operation according to the first tool path, operate the scanner to obtain scan data of a modified workpiece, and verify the first manufacturing operation based on the scan data of the modified workpiece.
