Abstract: Examples of methods are described herein. In some examples, a method includes determining a first portion within a build volume. In some examples, the method includes packing first objects in the first portion. In some examples, the method includes packing using a genetic procedure. In some examples, the method includes packing, using the genetic procedure, second objects in the build volume.

Abstract: Examples of structures are described herein. In some examples, a structure includes a lattice of posts. In some examples, the lattice of posts forms an opening between the posts. In some examples, the structure includes an appendage attached to a post of the posts. In some examples, the appendage extends over the opening. In some examples, the appendage is non-load bearing.

Abstract: Examples of methods are described herein. In some examples, a method includes simulating, using a physics simulation engine, a first sintering state of an object at a first time. In some examples, the method includes predicting, using a machine learning model, a second sintering state of the object at a second time based on the first sintering state. In some examples, a prediction increment between the first time and the second time is different from a simulation increment.

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 registering objects are described herein. In some examples, a method includes determining a set of overlap scores based on a set of orientations between a first bounding box of a three-dimensional (3D) object model and a second bounding box of a 3D scan of an object. In some examples, the method includes registering the 3D scan with the 3D object model based on the set of overlap scores.

Abstract: Examples of methods for adapting simulations are described herein. In some examples, a method may include simulating three-dimensional (3D) manufacturing. In some examples, the method may include adapting a boundary condition of the simulation of the 3D manufacturing based on a measurement from a thermal sensor at a point of a build enclosure.

Abstract: Examples of methods for part packing with diffusion auras are described herein. In some examples, a first diffusion aura for a first portion of a part is determined. In some examples, a second diffusion aura for a second portion of the part is determined. In some examples, the part is packed based on the first diffusion aura and the second diffusion aura.

Abstract: Systems and methods of predicting temperature during a build of a three-dimensional (3D) part include determining a temperature profile at a plurality of layers of a part based on geometric characteristics of the 3D part as defined by a 3D part file, and adjusting a process parameter of the build based on the determined temperature.

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.
