Abstract: 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.

Abstract: 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.

Abstract: Examples of methods for object manufacturing visualization by an electronic device are described herein. In some examples, a predicted thermal image of additive manufacturing is determined using a machine learning model. In some examples, a captured thermal image is obtained. In some examples, a graphical overlay of the predicted thermal image with the captured thermal image is presented.

Abstract: Examples of methods for object packing genetic procedures 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 includes determining a stagnant generation quantity that indicates an amount of generations subsequent to a leading generation with a leading chromosome score. In some examples, the method includes terminating the genetic procedure based on the stagnant generation quantity.

Abstract: 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.

Abstract: Examples of methods for object packings are described herein. In some examples, a method includes loading a first object in a first subset of a volume. In some examples, the method includes determining, using a genetic procedure, an arrangement of second objects in a second subset of the volume to produce a packing that includes the first object and the second objects.

Abstract: 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.

Abstract: Examples of methods for part packing are described herein. In some examples, a first subset and a second subset of a set of parts are determined. In some examples a first packing of the first subset is determined. In some examples, a second packing of the second subset is determined based on the first packing.

Abstract: 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.

Abstract: 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.
