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 of producing a shell layer of an output item in an additive manufacturing process comprises forming a first laterally intermittent shell layer (74) and at least one subsequent laterally intermittent shell layer (76), wherein each laterally intermittent shell layer (74,76) at least partially overlaps and joins with at least one of the other laterally intermittent shell layers.

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: A method comprises receiving object model data in an original coordinate system to print within a predefined usable build volume of a three dimensional printer. The method comprises receiving at least one compensation factor for the object model data to compensate for any shrinking of an object. The method comprises scaling the object model data by the at least one compensation factor to provide printable object model data. The scaling is performed with reference to an origin at a centre of the usable build volume.

Abstract: According to examples, machine-readable instructions may cause a processor to obtain a 3D mesh model of a part and to obtain a displacement map that defines amounts of displacements to be applied to various points in the 3D mesh model, in which the displacement map is at a first resolution. The processor may also generate a lower resolution version of the displacement map, in which the lower resolution is lower than the first resolution. The processor may further apply the lower resolution version of the displacement map on the 3D mesh model to generate an updated 3D mesh model.

Abstract: Examples of the present disclosure relate to a method in a three-dimensional printer for printing texture images. Lower resolution images of a texture image from a print file are generated and then selected based on volume pixels to be printed.

Abstract: In an example, a method includes receiving, at a processor, data representing at least part of an object to be manufactured in a layer-by-layer manufacturing process. A serialised octree representation of at least part of the object may be generated from the data. In the serialised octree representation, nodes are ordered such that (i) a node representing a volume which includes a layer of the object to be generated earlier in an intended order of object generation precedes a node representing a volume which consists of layer(s) of the object to be generated subsequently; (ii) nodes representing a volume which includes a given layer of the object are ordered based on a level of the nodes within the octree representation, wherein parent nodes appear before descendent nodes; and (iii) nodes representing a volume which includes a given layer of the object and being of the same level within the octree representation are ordered according to a location encoding pattern.
