  • Patent number: 12045944
    Abstract: Colored three-dimensional digital model generation techniques and systems are described. In one example, scanning techniques are employed by a scanning system that scans a physical object while disposed within packaging to form a three-dimension digital model. A model coloring system is employed to color the three-dimensional digital model. A two-dimensional digital image is employed that captures the same or similar physical object. In one example, features of the model are matched to the image. This is then used to align a viewing perspective with respect to the model with a viewing perspective of the object within the digital image, e.g., to find which “view” of the model corresponds with the image. The color is then applied from the digital image to the model, e.g., from pixels of the image to corresponding points in the model.

    Abstract: A three-dimensional object model is divided into slices that are targeted for an additive manufacturing process operable to deposit material at a variable deposition size ranging between minimum and maximum printable feature sizes. For each of the slices, a thinning algorithm is applied to contours of the slice to form a meso-skeleton. Topological features of the thinned slice are reduced over a number of passes such that a portion of the meso-skeleton is reduced to a single pixel wide line. Based on the number of passes, a slice-specific printable feature size within the range of the minimum and maximum printable feature sizes is determined. An adjusted slice is formed by sweeping the meso-skeleton with the slice-specific printable feature size. The adjusted slices are assembled into an object model which is used to create a manufactured object.

  • Patent number: 11896455
    Abstract: A method for generating a digital model of dentition, executed at least in part by a computer, acquires a 3-D digital mesh that is representative of the dentition along a dental arch, including includes braces, teeth, and gingival tissue. The method modifies the 3-D digital mesh to generate a digital mesh dentition model by processing the digital mesh and automatically detecting one or more initial bracket positions from the acquired mesh, processing the initial bracket positions to identify bracket areas for braces that lie against tooth surfaces, identifying one or more brace wires extending between brackets, removing one or more brackets and one or more wires from the dentition model, and forming a reconstructed tooth surface within the digital mesh dentition model where the one or more brackets have been removed. The modified 3-D digital mesh dentition model is displayed, stored, or transmitted over a network to another computer.

  • Patent number: 11886759
    Abstract: A method operates a three-dimensional (3D) metal object manufacturing system to compensate for displacement errors that occur during object formation. In the method, image data of a metal object being formed by the 3D metal object manufacturing system is generated prior to completion of the metal object and compared to original 3D object design data of the object to identify one or more displacement errors. For the displacement errors outside a predetermined difference range, the method modifies machine-ready instructions for forming metal object layers not yet formed to compensate for the identified displacement errors and operates the 3D metal object manufacturing system using the modified machine-ready instructions.
