  • Patent number: 10759118
    Abstract: In one embodiment of the present invention, a print orientation tool efficiently determines an orientation of a three-dimensional (3D) model such that, when 3D printed, the structural integrity of the resulting 3D object is optimized. In operation, the print orientation tool configures a stress analysis engine to slice the 3D model into two-dimensional (2D) cross-sections. The stress analysis engine then compute structural stresses associated with the 2D cross-sections. The print orientation tool translates the structural stresses to weakness metrics. Subsequently, the print orientation tool evaluates the orientations of the cross-sections in conjunction with the corresponding weakness metrics to select a printing orientation that minimizes weaknesses in the 3D model. Advantageously, by aligning the 3D model to the print bed based on the optimized printing orientation, the user mitigates weaknesses in the corresponding 3D object attributable to the 3D printing manufacturing process.

A boundary may then be calculated to be associated with each of the points based on the depth information at, and surrounding, each point. Each of the boundaries are extended outward until junctions are identified as bounding the boundaries in a direction. The system may determine whether the process is complete or not based on whether any of the calculated boundaries are currently unlimited in extent in any direction. Once the system determines that each of the boundaries is limited in extent, a 3D representation of the space may be generated based on the identified junctions and/or boundaries.

  • Patent number: 10613496
    Abstract: Systems and methods for generating designs of objects for additive manufacturing (AM) include a topological optimization framework that facilitates optimized computer generated designs requiring significantly reduced support structures. Towards this end, the concept of ‘support structure topological sensitivity’ is introduced. This is combined with performance sensitivity to result in a TO framework that maximizes performance, subject to support structure constraints. The robustness and efficiency of the proposed method is demonstrated through numerical experiments, and validated through fused deposition modeling, a popular AM process.

  • Patent number: 10579039
    Abstract: Physical tools for trimming operations in forming of a sheet-metal part are set up based on numerically-simulated structural behaviors. FEA model representing a stamped sheet metal before trimming and a trimming operation setup are received. Each trim-steel contains a set of cutting-edge nodes associated with trim vector. At least one trim line is established by projecting cutting-edge nodes onto the FEA model according to the trim vector. Numerically-constrained node-pairs along the trim line are created at intersections with edges of crossed finite elements. FEA model is modified by splitting the crossed finite elements to preserve original geometry and to ensure numerical stability. New finite elements are defined using one of the nodes in corresponding node-pairs such that no finite element straddles the trim line. At each solution cycle of a time-marching simulation of trimming operations, simulated structural behaviors are obtained as the scrap portion(s) deforms and falls accordingly.

    Abstract: Systems and methods are provided, in which an input module receives a model file, configuration(s) and cost parameters, and a processing unit selects and updates orientation sets for the model, and calculates the received cost parameters for pairs of orientation and configuration. Systems and methods further calculate for each orientation, a cost function value by weighting the calculated cost parameters according to the configuration(s) and display the calculated cost function values for the orientations on a respective sphere in a user interface. The sphere may be colored according to the cost function values, the orientation set may be enhanced and costs may be recalculated according to the cost function, and various information and statistics may be presented on the sphere. Finally, a selected orientation may be used to define the printing configuration and parameters and be used to provide a 3DP file.
