Abstract: In an example, a method comprises receiving, at a processor, a digital model representing an object to be produced by additive manufacturing. The method may comprise receiving, at the processor, an indication that a first selected region of a surface of the object is to have a first coating applied after printing. The method may further comprise applying a first predefined surface roughness pattern to the first selected region of the surface of the digital model.

Abstract: Examples of methods for determining displacement maps are described herein. In some examples of the methods, a method includes determining a displacement map for a three-dimensional (3D) object model based on a compensated point cloud. In some examples, the method includes assembling the displacement map on the 3D object model for 3D manufacturing.

Abstract: Object geometry for three-dimensional printers is described in which a first object to be three-dimensionally printed is identified. Geometry data relating to a geometry of all or part of the first object can be obtained. The geometry data can be compared with a predetermined threshold. A determination can be made as to whether the first object may or may not be adversely affected by a post-processing apparatus that will be used to process the object during a post-processing operation based on the comparison.

Abstract: In an example, a method includes receiving, by at least one processor, object model data describing a first object to be generated in additive manufacturing and an intended object generation location of the first object, wherein the intended object generation location is a relative location within a generic fabrication chamber. The method may further comprise determining, by at least one processor, a location for generation of the first object in a first fabrication chamber, wherein the first fabrication chamber is an intended fabrication chamber of object generation. The location may be an absolute location in the first fabrication chamber which corresponds to the relative location within the generic fabrication chamber.

Abstract: In an example, a machine-readable medium stores instructions which, when executed by a processor, cause the processor to: update a 3D printing geometrical compensation model with at least one correction determined using a combination of a dimensional correction determined from measurements of objects generated using a first geometrical compensation and a dimensional correction determined from measurements of objects generated using a modified version of the first geometrical compensation.

Abstract: Examples of the present disclosure relate to a method for packing three dimensional (3D) models. The method comprises identifying a plurality of sections of each 3D model according to curvature profiles of the sections; associating a build material layer thickness to each section of the plurality of sections, whereby each associated build material layer thickness is one of a set of pre-established build material layer thicknesses; packing the plurality of 3D models according to each associated build material layer thickness, whereby packing comprises spatially arranging at least some 3D models in the 3D virtual build volume according to one or more criteria, such that at least some of the sections of different 3D models associated to a same build material layer thickness are arranged in a same region of the 3D virtual build volume.

Abstract: A method of processing merged 3D geometric information in a 3D printing system is described that receives a 3D object model file representing at least two physical 3D parts to be printed, wherein the 3D object model file comprises 3D geometric information for the at least two physical 3D parts, wherein the 3D geometric information is encoded as at least one logical 3D part, wherein at least one of the at least one logical 3D part comprises merged 3D geometric information for at least a subset of the at least two physical 3D parts. From the 3D object model file, a separate set of 3D geometric information for each of the at least two physical 3D parts is extracted and each separate set of 3D geometric information is processed individually before printing the physical 3D parts.

Abstract: An apparatus has a processor and a machine-readable storage medium storing machine-readable instructions executable by the processor. The processor is to create a 3D print job defining a spatial arrangement of objects to be printed such that each object or each object portion is arranged in a region or regions having a build material layer thickness corresponding to a user-specified build material layer thickness and such that objects or object portions having different build material layer thicknesses are arranged in different regions. Different build material layer thicknesses may be user-specified for different objects or different object portions.

Abstract: A method comprises: determining, from build data comprising one or more build elements each of which is a representation of a portion of an object of one or more objects to be generated by an additive manufacturing system, a property of at least one build element of the one or more build elements; and determining, based on the property of the at least one build element, whether generating the one or more objects using the build data would result in generating the object with a generation defect.

Abstract: In an example, a method includes receiving, at a processor, an indication of a volume of a fabrication chamber and determining a characteristic of a build material for use in fabricating an object within the fabrication chamber. Based on the build material characteristic, a virtual object volume within the fabrication chamber may be determined, wherein the virtual object volume provides a virtual boundary within which to position virtual objects representing objects to be generated in the fabrication chamber.
