Methods and apparatus for manufacturing objects having optimized response characteristics

Номер: US20120165967A1
Автор: James A. St. Ville
Принадлежит: Aztec IP Co LLC

A method for manufacturing an object having a potential {x} which is generated in response to a field {f} applied thereto is provided. The method includes the step of designing a geometric model of the object. A computerized mathematical model of the object is generated by discretizing the geometric model of the object into a plurality of finite elements and defining nodes at boundaries of the elements, wherein values of the field {f} and potential {x} are specified at the nodes. A material property matrix [k] is then calculated based on the relationship {f}=[k] {x}. Material property coefficients are then extracted from the material property matrix [k] for each finite element in the computerized mathematical model and the extracted material property coefficients are compared to material property coefficients for known materials to match the extracted material property coefficients to the material property coefficients for known materials. Manufacturing parameters corresponding to the matched material property coefficients are then determined. The object is then manufactured in accordance with the determined manufacturing parameters.

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. 1.

Techniques for generating motion scuplture models for three-dimensional printing

Принадлежит: Autodesk Inc

In one embodiment of the present invention, a motion effect generator enables the creation of tangible representations of the motion of three-dimensional (3D) animated models for 3D printing. In operation, the motion effect generator receives a 3D animated model and animates the model through a configurable interval of time. As the motion effect generator animates the model, the motion effect generator applies a motion depiction technique to one or more selected components included in the model—explicitly portraying the motion of the 3D animated model as static motion effect geometries. Subsequently, based on the motion effect geometries, the motion effect generator creates a 3D motion sculpture model that is amenable to 3D printing. By automating the design of motion sculpture models, the motion effect generator reduces the time, sculpting expertise, and familiarity with 3D printer fabrication constraints typically required to create motion sculpture models using conventional, primarily manual design techniques.

An improved part optimization process in additive manufacturing is provided, which uses a finite element analysis only where boundary parameter differentiation is detected. For a given part being manufactured, such as in DMLS, thermal effects of adjacent volumes with no boundary parameter differentiation are ignored in the part optimization process. For example, if a given volume is over a volume of the same material, no computational analysis is conducted, but if a volume of metal is over air, then the computational analysis is conducted. This results in significantly less computational time being required. Further, the present invention uses computation equipment remote from the DMLS part production equipments, connected instead via the internet or other such “cloud computing” arrangements. 1.

THREE-DIMENSIONAL OBJECT-MANUFACTURING APPARATUS, THREE-DIMENSIONAL OBJECT-MANUFACTURING METHOD, AND PROGRAM

Номер: US20180079138A1
Автор: TANAKA Hiroya
Принадлежит: KEIO UNIVERSITY

In a three-dimensional object-manufacturing apparatus, a Hamilton path-calculating part generates, on the basis of three-dimensional shape data representing a shape of a three-dimensional object, a voxel model representing an internal structure for forming the three-dimensional object. The Hamilton path-calculating part also determines whether a Hamilton path can be established in the voxel model. When it is determined that a Hamilton path cannot be established in the voxel model, a subvoxel-generating part divides the voxels to generate subvoxels. The Hamilton path-calculating part establishes a Hamilton path in the voxel model. A tool path data-generating part generates a tool path for forming a forming material based on the established Hamilton path. A three-dimensional object-forming unit implements the forming of the three-dimensional object on the basis of the tool path. 1. A three-dimensional object-manufacturing apparatus comprising:a voxel model-generating unit that, on the basis of three-dimensional shape data representing a shape of a three-dimensional object, generates a voxel model representing internal structure for forming the three-dimensional object;a judging unit that judges whether a Hamilton path can be established for the voxel model generated by the voxel model-generating unit;a subvoxel-generating unit that, when it is judged by the judging unit that a Hamilton path cannot be established for the voxel model, divides voxels of the voxel model to generate subvoxels;a Hamilton path-establishing unit that establishes a Hamilton path for the voxel model;a tool path-generating unit that generates a tool path for forming a forming material on the basis of the Hamilton path established by the Hamilton path-establishing unit; anda three-dimensional object-forming unit that implements forming of the three-dimensional object on the basis of the tool path generated by the tool path-generating unit.2.
