Abstract: A system and method that relies on the principles of material science, deformable body mechanics, continuum mechanics and additive manufacturing to reduce the costs associated with additive manufacturing. Physical properties are used by numerical solution methods, such as the Finite Element Method (FEM) or Smooth Particle Hydrodynamics (SPH), to deform an original model of an object to be manufactured into a viable configuration that reduces fabrication material, time, and cost when manufacturing an object through additive manufacturing.

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.

Abstract: Methods of optimizing additive manufactured three dimensional structures that are designed to output a desired set of optical properties, particularly for use in tactile-based sensing applications. The optical properties within an object are highly-customizable and can be altered on a voxel-by-voxel level, such that the resulting optical properties can be used in applications in which discreet points within the object are interactable in different ways, thereby providing for different sensations depending on the selected discreet point. Moreover, the selected optical properties can differ between adjacent voxels, allowing for precise customization of the object depending on the requirements of the manufactured object. As a result, the resulting three dimensional structures include a precise, desired set of optical properties, providing for intricate interactions by a user in tactile applications.

Abstract: Methods of optimizing additive manufacturing processes for improved efficiencies and accuracies, particularly by simplifying the user interface portions of the processes. The methods use path-finding calculations, such as vector fields, vector trails, and texture maps, to form accurate models from which replica composite objects can be printed, without requiring complex parameter inputs and calculations from the user. The methods measure and plot vector fields by considering the location of a particle within the volume of an object at various points of time to develop a strand-like model that is used to manufacture a replica object.

Abstract: A method of selecting, printing, and removing a support removal structure from an additive manufactured object, such that the support removal structure provides structural support for the object during printing. The inclusion of support removal structure within a printed object prevents the object from collapsing during printing. After the printed object is completed and cured during post-processing, the support removal structure is removed from the object to provide an object including accurate physical properties. The support removal structure is elongated and compliant and is specially designed for an individual printed object to provide optimal support during a printing process without tangling during removal.
