摘要： A system and method for toolpath creation is provided. The method includes exporting CAD defined 3-D geometry to a slicing module; slicing the 3-D geometry creating a set of 2-D patterns representing the 3-D geometry; generating vector code from the set of 2-D patterns; and translating the vector code to machine code.

摘要： The invention relates to a method for removing material from a three-dimensional surface (1) of any shape in a single or multilayered manner by means of a material removing agent (9), such as a laser, that acts in points on the a surface and where a surface structure (2) is applied to the three-dimensional surface (1); wherein the inventive methods can be carried out in such a way that the surface (1) is described by a mathematical function and approximated by a polygon whereby each polygon of the polygon network is assigned to a work area for the laser. Raster images are associated with each of the polygons, which determine the depth values for the surface structure. The polygons (3) are removed line by line. When the depth values of the surface structure differ by a large margin, the material removal takes place in several layers (7) of polygon networks.

摘要： The subject disclosure is directed towards technology managing three-dimensional object fabrication in full color. In order to transform the object's model into an instruction set for a fabrication device, a fabrication manager computes color values corresponding to geometry within a later of the object's model. After determining an amount of each colored material to deposit, the fabrication manager generates coordinated instructions configured to deposit a combination of colored materials according to the geometry and efficiently transitioning between colored materials during object fabrication.

摘要： An apparatus and methods for generating geometric data for use in an additive manufacturing process. The apparatus includes a processing unit. The processing unit may be arranged for receiving data defining surface geometry of a plurality of objects to be built together in an additive manufacturing process, providing a user interface that allows a user to define a location of each object within a common build volume and carrying out a slicing operation on at least one of the objects located in the common build volume independently from another one of objects located in the common build volume. The slicing operation determines sections of the at least one object to be built in the additive manufacturing process. In one embodiment, the objects are defined in a hierarchical data structure. Supports for supporting the objects during the build may be defined with reference to a 2-dimensional support cross-section.

摘要： The subject disclosure is directed towards three-dimensional object fabrication using an implicit surface representation as a model for surface geometries. A voxelized space for the implicit surface representation, of which each machine addressable unit includes indirect surface data, may be used to control components of an apparatus when that apparatus fabricates a three-dimensional object. Instructions generated using this representation may cause these components to move to surface positions and deposit source material.

摘要： Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for 3D printing without preprocessing a CAD model before delivery to a 3D printer. The CAD model for a design to be printed is received by a 3D printer. Instructions are generated for printing the first slice. While the instructions are used to start printing the CAD model, dynamic real-time slicing is performed on a remaining portion of the CAD model. Preprocessed data, model analysis information or real-time feedback is received during the printing of a respective slice. A next slice is identified, and slicing parameters are adjusted, including adjusting a slicing parameter for the next slice. Instructions for printing the next slice are generated. The next slice is printed based on the generated instructions. Dynamic real-time slicing is repeated to generate a then next slice and associated printing instructions.

摘要： One embodiment of the invention is a slicing engine that generates two or more slices of a virtual 3D model given a slice plane. The slicing engine then determines connection points on each of the slices that indicate how the 3D model is to be reconnected by the user when the 3D model is fabricated. The slicing engine also determines an optimized layout for the various slices of the 3D model on fabrication material for minimal use of the material. The user is then able to “print” the layout on the fabrication material via 3D printers, and connect the various printed slices according to the connection points to build a physical representation of the 3D model.
