  • Patent number: 10434007
    Abstract: A technique for fabricating a surgical splint for use in correcting a dental condition of a patient. The technique involves obtaining a three-dimensional digital model of lower and upper arch dentitions of the patient having the dental condition. Relative positions of the lower and upper arch dentitions are adjusted with respect to each other in the three-dimensional digital model using a computing device. An electronic model of a splint is generated based on the adjusted relative positions of the lower and upper arch dentitions. A splint is then generated in a physical form from the electronic model of the splint.

  • Patent number: 10421238
    Abstract: The hardware and software properties of a three-dimensional printer can be queried and applied to select suitable directly printable models for the printer, or to identify situations where a new machine-ready model must be generated. The properties may be any properties relevant to fabrication including, e.g., physical properties of the printer, printer firmware, user settings, hardware configurations, and so forth. A printer may respond to configuration queries with a dictionary of capabilities or properties, and this dictionary may be used to select suitable models, or determine when a new model must be created. Similarly, when a printable model is sent to the printer, metadata for the printable model may be compared to printer properties in the dictionary to ensure that the model can be fabricated by the printer.

  • Patent number: 10386828
    Abstract: Disclosed are methods of optimizing a computerized model which relates etched feature profile on a semiconductor device to a set of independent input parameters via the use of a plurality of model parameters. The optimization methods may include modifying the model parameters so that an etch profile generated with the model is such that it reduces a metric indicative of the combined differences between experimental etch profiles resulting from experimental etch processes performed using different sets of values for sets of independent input parameters and computed etch profiles generated from the model and corresponding to the experimental etch profiles. Said metric may be calculated by projecting computed and corresponding experimental etch profiles onto a reduced-dimensional subspace used to calculate a difference between the profiles. Also disclosed herein are systems employing such optimized models, as well as methods of using such models to approximately determine the profile of an etched feature.

    Abstract: A raft to support a three-dimensional object on a build platform of a three-dimensional printer can be fabricated with a controlled adhesion pattern to improve overall raft performance. For improved raft-to-build platform adhesion, an exterior portion around the perimeter of the raft may be fabricated with greater adhesion (per unit of surface area covered by the exterior portion) than an interior portion. This can be accomplished by varying the volume of build material, varying the printing height, or using different patterns of build material. At the same time, adhesion of the raft to a printed object built thereon can be controlled with a number of techniques such as using specific build patterns for the top layer of the raft or varying printing heights (e.g., z-axis position) between the top of the raft and the bottom of the object.

  • Patent number: 10073440
    Abstract: A method of designing and manufacturing a replica composite object based on an original object. The method identifies the structure and physical properties of an original object. Base materials, bodies, and structural templates, each of which includes associated physical properties, are utilized to generate a 3-dimensional model. The 3-dimensional model is discretized and tested to determine if the selected combination of base materials and bodies have physical properties that substantially equal the physical properties of the original object. If the physical properties do not equate, the 3-dimensional model is optimized by adjusting the combination of base materials, bodies, and structural templates. When the difference between the measured physical properties of the 3-dimensional model and the identified physical properties of the original object is less than a tolerance value, the method instructs an additive manufacturing system to generate a replica composite object based on the original object.

  • Patent number: 10061870
    Abstract: A system and a method automate metrology, measurement, and model correction of a three dimensional (3D) model for 3D printability. Slices of the 3D model are received or generated. The slices represent 2D solids of the 3D model to be printed in corresponding print layers. Medial axis transforms of the slices are calculated. The medial axis transforms represent the slices in terms of corresponding medial axes. A local feature size at any point along a boundary of the slices is determined as the shortest distance from the point to a corresponding medial axis.

  • Patent number: 10046522
    Abstract: A method for printing a three-dimensional part in an additive manufacturing process, which includes calculating surface plane angles relative to one or more of the coordinate axes as a function of surface area of the surface geometry, calculating a build score for each coordinate axis as a function of the calculated surface plane angles, and selecting an orientation for the digital model in the coordinate system based at least in part on the calculated build scores. The build scores preferably predict which part orientations are likely to provide good surface quality for the printed three-dimensional part.

  • Patent number: 10025294
    Abstract: Embodiments described herein relate generally to simulating apparel items. A matching computer system may receive a request for an apparel item. The matching computer system may identify a 3D pattern corresponding to the apparel item. The matching computer system may provide this 3D pattern to a user agent computer system. The user agent computer system may cause a 3D printer to print a 3D artifact or modify an existing 3D artifact to simulate the requested apparel item. The modification of 3D artifact may be based on the data collected by the sensor(s) attached to the user which indicate the fitting and/or user feelings of the 3D apparel. The user agent computer system may print or modify the 3D artifact to include components that simulate characteristics of the requested apparel item. The 3D artifact may provide feedback to the user agent computer system based on sensing measurements. Other embodiments may be described and/or claimed.
