Publication/Patent Number: US2021001542A1 Publication Date: 2021-01-07 Application Number: 16/460,543 Filing Date: 2019-07-02 Inventor: Villette, Thibault   Assignee: Saudi Arabian Oil Company   IPC: B29C64/153 Abstract: A system and method for optimizing an additive manufacturing process in which a reinforcement material is randomly introduced to a fabrication bed. An image of the fabrication bed is captured. The image is analyzed by code in a computer to identify the actual arrangement of the randomly deposited reinforcement material relative to the object being manufactured. Based on the image data showing the reinforcement material, a toolpath is dynamically determined that incorporates the random reinforcement material. Accordingly, the toolpath incorporates the reinforcement material into the structure of the object, which can result in a reduction of the total amount of raw material is fused to create the object being manufactured.

For each of the slices, a thinning algorithm is applied to one or more contours of the slice to form a meso-skeleton, where topological features of the thinned slice that are smaller than the minimum printable feature size are reduced to skeletal paths. A corrected slice is formed using the meso-skeleton by sweeping the meso-skeleton with the minimum printable feature size. The corrected slices are assembled into a corrected object model and the corrected object model is used in the additive manufacturing process.

METHOD FOR THE DESIGN AND MANUFACTURE OF COMPOSITES HAVING TUNABLE PHYSICAL PROPERTIES
Publication/Patent Number: US2021026325A1 Publication Date: 2021-01-28 Application Number: 16/948,989 Filing Date: 2020-10-08 Inventor: Lobo, Fenoglietto Fluvio   Stubbs, Jack   Assignee: University of Central Florida Research Foundation, Inc.   IPC: G05B19/4099 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.
