  • Publication number: 20140309764
    Abstract: The subject disclosure is directed towards adapting a three-dimensional model to surface geometry when fabricating a three-dimensional object. While partitioning model data into planar regions and non-planar regions of the three-dimensional object, the model data associated with the non-planar regions is modified to more accurately generate a path that follows the object's curved surface geometry. This path is transformed into an instruction set, which when executed by a device, causes movement along the path while depositing material on the three-dimensional object.

  • Patent number: 8862260
    Abstract: The invention relates to a process or device for the production of a three-dimensional object by layer-wise solidification of a material which is solidifiable under the application of electromagnetic irradiation by means of mask illumination, wherein the mask is produced using an image forming unit having a prescribed resolution, which is formed from a constant number of image forming elements (pixels) being discrete and being arranged in a spatially mutually fixed manner. For the improvement of the resolution along the outer and inner contours of the sectional areas of the object to be generated layer-wise in the sub-pixel range, a multiple illumination per layer is performed, which consists of a series of multiple images that are mutually shifted in the sub-pixel range in the image/construction plane, wherein a separate mask/bitmap is produced for each shifted image.

  • Publication number: 20140297014
    Abstract: The subject disclosure is directed towards three-dimensional object fabrication using an implicit surface representation as a model for surface geometries. A voxelized space for the implicit surface representation, of which each machine addressable unit includes indirect surface data, may be used to control components of an apparatus when that apparatus fabricates a three-dimensional object. Instructions generated using this representation may cause these components to move to surface positions and deposit source material.

  • Publication number: 20140277678
    Abstract: Certain examples provide systems, methods, and apparatus for patient care and support. An example three-dimensional printed model of a portion of a patient anatomy is to be formed for the patient based on image data obtained of the patient. The three-dimensional printed model includes an output device to provide an output from the three-dimensional printed model that is perceptible to the patient. The three-dimensional printed model includes a communication device to facilitate exchange of information between the three-dimensional printed model and one or more external systems. The three-dimensional printed model includes a controller to facilitate exchange of information, via the communication device, between the three-dimensional printed model and the one or more external systems. The controller is also to provide feedback to the patient via the output device with respect to a condition affecting the portion of the patient anatomy represented by the three-dimensional printed model via the output device.

  • Publication number: 20140277661
    Abstract: The subject disclosure is directed towards technology managing three-dimensional object fabrication in full color. In order to transform the object's model into an instruction set for a fabrication device, a fabrication manager computes color values corresponding to geometry within a later of the object's model. After determining an amount of each colored material to deposit, the fabrication manager generates coordinated instructions configured to deposit a combination of colored materials according to the geometry and efficiently transitioning between colored materials during object fabrication.

  • Patent number: 8838263
    Abstract: The unique advantages of computer-controlled fabrication of a patient-specific orthotic device using an automated fabrication machine capable of following computer instructions to create 3D surface contours and new developments in non-invasive three-dimensional (3D) scanning have made it possible to acquire digital models of freeform surfaces such as the surface anatomy of the human body and to then fabricate such a patient-specific device with high precision. Such a patient-specific device brings significant improvement in patient-specific fit, comfort, and function of medical devices (and, in particular, to orthoses that require a close fit to the wearer's body to act effectively). The combination of these two technologies is ideally suited for the development of patient-specific orthotic devices. A patient specific ankle-foot orthotic device using this technology is disclosed. This exemplary device is used to help stabilize the ankle-foot region, for example, in patients with impaired gait.

  • Publication number: 20140257549
    Abstract: A 3D object (the “New Object”) is fabricated layer by layer by 3D printing. The shape and relative dimensions of the various parts of the New Object match that of another 3D object (the “Target Object”). In addition, the exterior of the New Object appears to be a photographic likeness of the Target Object. The “photographic” likeness is created by variations in visual characteristics of materials in the layers comprising the New Object, and in particular by variations at or near the surface of the New Object. Thus, the photographic likeness is an integral part of these layers comprising the New Object. An object is scanned, from which a texture map is obtained. A CAD model is sliced into slices (bit maps files) which are then colored by a program with the boundary to match the color or gray scale to color the appropriate pixels, derived from the texture map.

  • Patent number: 8818544
    Abstract: A method for calculating a support material volume, the method comprising generating a grid of cells for a tree data structure of a digital part, where the cells define a plurality of cell arrays, and pinging the cells of one of the cell arrays until a cell containing a subset of the tree data structure is reached or until each cell in the cell array is pinged, where if a cell containing the subset of the tree data structure is reached, then designating the reached cell and all remaining unpinged cells in the cell array as filled. The method also includes repeating the pinging step for each remaining cell array to determine a total filled volume, and subtracting a volume of the digital part from the total filled volume to determine a support material volume.

  • Patent number: RE45067
    Abstract: The invention concerns a contactless numerical printing machine for products of average fluidity, such as varnish, glue, and conducting or scratchable ink, onto a substrate of variable thickness and dimensions. The machine includes a special device for printing without contact by projection. The projected materials are materials of average fluidity or composed of large-dimension molecules. The process used includes an electro-acoustic device for control of the projection, and a multiplicity of projection nozzles, each controlled individually. The machine also includes a production chain with different work stations, whose printing devices are controlled by a computer management system. The production chain allows printing with a certain precision in given zones located during the processing by an appropriate work station.
