摘要： Examples of methods for generating supports are described herein. In some examples, a method includes determining a starting position from a set of voxels of a three-dimensional (3D) object model to be additively manufactured. In some examples, the method also includes generating a support for the 3D object model by traversing a cost field from the starting position.

摘要： According to examples, a three-dimensional (3D) fabrication system may include fabrication components and a controller. The controller may control the fabrication components to fabricate parts of a 3D object in a build envelope, the parts to be assembled together to form the object, and in which the parts are fabricated at locations corresponding to relative positions of the parts with respect to each other in the assembled object. The controller may also control the fabrication components to fabricate a cage around the parts in the build envelope.

摘要： An example non-transitory computer-readable medium includes instructions that, when executed by a processor, cause the processor to retrieve a plurality of parts to be three-dimensionally (3D) printed and an output rate indicative of a rate at which previous 3D printed parts have been output, select a packing parameter that results in a packing time corresponding to the output rate, and compute a part packing of the plurality of parts for a print bed according to the packing parameter.

摘要： An image processing system acquires a first three-dimensional model of an object. The image processing system includes a processor and storage medium encoded with instructions executable by the processor. The instructions include instructions to define a material potential function for a material. The material potential function is a function of a three-dimensional origin point of the material in the object, a three-dimensional propagation limit of the material in the object, and a three-dimensional propagation function of the material in the object. The instructions include instructions to generate a second three-dimensional model of the object based in part on the material potential function and the first model. The second model illustrates propagation of the material through an interior volume of the object at a unit level. A controller generates control signals based on the second model, and a fluid ejection engine performs an additive manufacturing process based on the control signals.

摘要： Examples of methods for object group packings are described herein. In some examples, a method includes ordering objects of a chromosome into a first group and a second group in accordance with a first priority and a second priority. In some examples, the method includes determining, using a genetic procedure in accordance with the first priority and the second priority, a first arrangement within the first group and a second arrangement within the second group to produce a packing in a volume.

摘要： Examples of methods for object packings are described herein. In some examples, a method includes generating chromosomes in a genetic procedure. In some examples, each chromosome indicates a packing of objects in a volume. In some examples, the method also includes determining uniformity scores corresponding to the chromosomes. In some examples, each uniformity score is based on object orientation similarity. In some examples, the method further includes selecting a chromosome based on the uniformity scores.

摘要： Examples of methods for determining chromosome expiration are described herein. In some examples, a method includes generating, in a genetic procedure, chromosomes indicating object packing positions. In some examples, the method includes determining whether a chromosome of the chromosomes is expired. In some examples, the method includes excluding the chromosome from a subsequent generation in response to determining that the chromosome is expired.

摘要： Examples of methods for determining object packings are described herein. In some examples, a method includes determining, for each of a plurality of objects, an initial orientation corresponding to a minimum bounding box. In some examples, the method includes determining a packing of the plurality of objects using the initial orientations with a genetic procedure.
