Abstract: An example system includes a simulation engine to determine a plurality of thermal states that will be experienced by powder at a voxel of a three-dimensional print volume as a result of printing a particular build. Each thermal state corresponds to a time during the printing or cooling from the printing. The system includes a stress engine to calculate a stress to the powder at the voxel based on the plurality of thermal states. The system includes a degradation engine to determine an amount of degradation of the powder at the voxel based on the stress.

Abstract: Examples of methods are described. In some examples, a method includes dispensing, during a printing procedure, a thermochromic dye on a layer of material in a build volume. In some examples, the method includes detecting, after the printing procedure, a temperature in an aural region of an object in the build volume based on a color of the thermochromic dye.

Abstract: Examples of apparatuses for agent map generation are described. In some examples, an apparatus includes a memory to store a layer image. In some examples, the apparatus includes a processor coupled to the memory. In some examples, the processor is to generate, using a machine learning model, an agent map based on the layer image.

Abstract: A computing device comprising a controller is disclosed herein. The controller is to access print data of a virtual build volume including a 3D object to be generated by a 3D printer; modify the print data to include a 3D structure at a location within the build volume to encapsulate an amount of build material; receive powder degradation data corresponding to the powder degradation of the encapsulated amount of build material; and calibrate an additive manufacturing parameter based on the powder degradation data.

Abstract: Examples of methods for thermal image determination are described. In some examples, a method may include determining, using a first machine learning model, a first thermal image of a first layer of additive manufacturing. In some examples, the method may include determining, using a second machine learning model, a second thermal image of a second layer based on a simulated thermal image. The second thermal image may have a second resolution that is greater than a first resolution of the simulated thermal image in some examples. In some examples, the method may include determining, using a third machine learning model, a third thermal image based on the first thermal image and the second thermal image.

Abstract: Examples of methods for simulating three-dimensional (3D) manufacturing of an object are described herein. In some examples, a method includes simulating 3D manufacturing of an object based on a value. In some examples, the value indicates a sub-voxel proportion of a voxel that is occupied by the object. Some examples of the methods may include determining the value for the voxel.

Abstract: Examples of methods are described. In some examples, a method may include dispensing a thermochromic dye. In some examples, the thermochromic dye may be dispensed on a fusing layer of a build volume. In some examples, the method may include measuring a temperature of the fusing layer indicated by an optical image of the thermochromic dye.

Abstract: Examples of methods for powder reclamation are described. In some examples, a method includes estimating powder degradation for voxels of a three-dimensional (3D) manufacturing build based on a simulation. In some examples, the method includes determining a quantity of reclamation powder. In some examples, the quantity of reclamation powder may be determined based on the estimated powder degradation.
