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 design element placement on 3D surfaces are described herein. In some examples, a three-dimensional (3D) mesh of a 3D surface is converted to a two-dimensional (2D) surface. In some examples, placement of design elements on the 2D surface is determined to maximize density of the design elements while satisfying a minimum separation distance between the design elements. In some examples, the design element placement on the 2D surface is converted to the 3D surface.

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: 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 disclosed herein relate to 3D printer fresh and recycled powder supply management. In one implementation, a processor estimates fresh and recycled powder use and recycled powder creation by a 3D printer based on a set of print jobs.

Abstract: According to examples, a processor may identify locations on a digital 3D model of an object corresponding to positions at which features are to be added to the object. For each of a plurality of locations of the identified locations, the processor may identify displacements of each of a plurality of patch points around the location from the surface of the digital 3D model. The processor may also create a map of the digital 3D model that encodes the identified displacements of the patch points around the locations, in which a 3D fabrication system is to fabricate the object to include the plurality of features based on the digital 3D model and the created map.

Abstract: In an example in accordance with the present disclosure, a fiber molding screen is described. The fiber molding screen includes a first region and a second region. The fiber molding screen includes a first set of pores formed within the first region. Each pore of the first set of pores has a first pore trajectory angle between a longitudinal axis of the pore and the first region surface. The fiber molding screen also includes a second set of pores formed within the second region. Each pore of the second set of pores has a second pore trajectory angle between a longitudinal axis of the pore and the second region surface. The second pore trajectory angle is different than the first pore trajectory angle.

Abstract: The present disclosure relates to the technical field of body-shaping garments, and specifically to a multi-layer fabric with patterns and a body-shaping garment. The multi-layer fabric includes a top fabric layer, a lining fabric layer, and an intermediate fabric layer between the top fabric layer and the lining fabric layer. The intermediate fabric layer includes a hollow pattern. The portion of the top fabric layer that corresponds to the hollow pattern is a see-through mesh structure, and the portion of the lining fabric layer that corresponds to the hollow pattern is a certain color so that the certain color is viewable through the see-through mesh structure of the top fabric layer.

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: Examples of screen structures are described herein. In some examples, a screen structure may include an input side. In some examples, the screen structure may include a drainage side to be disposed on an extraction surface. In some examples, the screen structure may include a plurality of channels through the screen structure between the input side and the drainage side. In some examples, the screen structure may include a plurality of protruding structures on the input side, wherein the screen structure is three-dimensionally (3D) printed.

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.

Abstract: Examples of methods are described. In some examples, a method includes generating, using a first branch of a machine learning model, a first agent map based on a layer image. In some examples, the method includes generating, using a second branch of the machine learning model, a second agent map. In some examples, the first agent map and the second agent map indicate printing locations for different agents.
