Appl. No.:

12/483903

Inventors:

Wolfgang Seibold - Louisville CO, US

International Classification:

G06F 17/50
G05B 19/19

US Classification:

700 98, 700182, 700162

Abstract:

A computer readable storage medium includes executable instructions to obtain an orbital path shape. Each point on the orbital path shape represents a displacement of the tool shape when the tool shape is moved along the orbital path shape The tool shape, when moved along the orbital path shape, sweeps out a desired cavity shape. The executable instructions further include instructions to obtain an input solid model corresponding to the desired cavity shape to be swept out and derive a set of faces for a solid model of the tool shape based on the orbital path shape and a set of faces, a set of edges and a set of vertices corresponding to the input solid model. The executable instructions further include instructions to combine a subset of the set of faces derived for the tool shape to generate the solid model of the tool shape. In one embodiment, the tool shape corresponds to a Minkowski decomposition of the input solid model with respect to the orbital path shape.

Abstract:

Computer-implemented systems and methods for preparing a virtual three-dimensional (3D) object for 3D printing are provided. A hollowed-out representation of an input model is generated. The input model defines a solid virtual 3D object, and the hollowed-out representation comprises a shell and an internal volume that is a void. The internal volume is meshed to generate a polygonal mesh representation of the internal volume. A lattice microstructure corresponding to the polygonal mesh representation is generated by (i) replacing each edge of the polygonal mesh representation with a solid part, and (ii) uniting the solid parts to form the lattice microstructure. A lightweight representation of the input model is generated, where the lightweight representation comprises the shell and the lattice microstructure.
