Abstract:
Systems and methods are disclosed for contour crafting. The system includes a work tool configured to form a first layer by depositing material from a print head and following a path for depositing a second layer of material atop the first layer. The system further includes an optics assembly configured to produce a light pattern directed toward previously deposited material, and a camera configured to capture image data of the previously deposited material. The system further includes a processing device being configured to obtain, from the image data, a visible formation of the light pattern as it is projected onto the previously deposited material, and make a comparison of the visible formation to a predicted formation. The processing device is further configured to determine that the second layer is not aligned with the first layer, and adjust of the path being followed by the work tool based on the determination.
