Abstract: In an example, a method includes obtaining a plurality of models each representing an object to be generated in an additive manufacturing operation. In some examples the method further includes identifying a set of models of the plurality of models which represent instances of similar objects. The method may include determining whether the objects represented by the models of the set of models are to be generated relatively rotated with respect to one another. In some examples the method further includes, when the objects represented by the set of models are to be generated relatively rotated with respect to one another, providing an indication of the relative rotation.

Abstract: An apparatus has a processor and a machine-readable storage medium storing machine-readable instructions executable by the processor. The machine-readable instructions cause the processor to, upon obtaining an indication that a calibration of a 3D printing machine is to be performed, arrange user calibration objects to be printed and calibration objects to be printed and to be used in the calibration in a virtual build volume. Arranging calibration objects in the virtual build volume comprises arranging the calibration objects at print job specific locations reserved for calibration objects and/or replacing user objects with calibration objects.

Abstract: Provided are a system, method and computer program product for generating three dimensional models for use by an additive manufacturing or 3D printing system, in which object model data defining one or more objects to be built by a three-dimensional printing apparatus is input and used to generate a three dimensional model for a protective structure to surround the one or more objects. A user is provided with selectable configuration options for the protective structure. The method includes presenting, via a user interface, selectable configuration options for a protective structure to be built around the one or more objects by the three-dimensional printing apparatus. In response to user selection of one or more configuration options via the user interface, a three dimensional model for the protective structure is automatically generated.

Abstract: A method (2 analyses (4) a layer of a three-dimensional print job wherein the value of a parameter relating to the processing time of the layer is determined. The method (2) determines (6) whether the layer of the three-dimensional print job is to be printed in a three-dimensional printer. This determination is based on the value of the parameter relating to processing time.

Abstract: Object model data is obtained, defining an object to be generated by a three-dimensional printer. An envelope is obtained within which the object is to be generated, the envelope having a main section and at least one of a base and/or a lid, and printer control data is generated comprising build data to control a three-dimensional printer to generate the object and the envelope and a build mode data, wherein the printer control data comprises instructions to cause a three-dimensional printer to generate a build layer of the base and/or lid of the envelope using a first build mode, and to generate the object using a second build mode. The first build mode uses an extended time-per-build-layer for the generating of the build layer of the base and/or lid of the envelope compared with the second build mode.

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.
